  1. Bob, I can’t recall, were the FT-8000s available with Ford’s 7.8, or just CAT’s 3208? They were an interesting attempt at a low-cost tandem dump chassis. .
  2. Obama's "Deferred Action for Childhood Arrivals" (DACA) program allowed 690,000 illegal immigrants to stay in the country. Now, Trump is going to outdo Obama and allow up to 1.8 million illegal immigrants remain in the country (at the end of the day, the number will certainly reach and more likely exceed 1.8 million). This is all a "slap in the face" to all the people who go through the "legal" process of immigrating to the United States. Fools, they should have simply slipped in at night......the government won't make them leave, they can collect welfare and also send their illegal immigrant children to school. Then, they can have a US-born child to anchor the whole extended family in America.
  3. Iepieleaks / January 25, 2018 This Volvo FM crewcab was spotted by one of our friends during transport. This is probably going to be a heavy fire fighter truck, on its way to the bodybuilder. The double cab of the Volvo FM is not a common vehicle and we are curious if this is an official Volvo cab. And speaking of the Volvo FM, when is the next generation of this succesful vehicle to be launched? We did not see any prototypes on the road yet but something must be cooking in the Volvo kitchen to replace the good old, but small Volvo FM cab. .

  6. If you're not abusing the truck, I suggest you have your Mack brand dealer's service manager coordinate having you bring the truck down when his Mack district service representative is next in town for their regular visit.

  8. Bob's the Ford expert, but I think the basic cab design (updates aside) was the same used on the light trucks from 1980 to 1997.
  9. How many Americans want to buy a Chinese Communist Party (CCP) built truck? That's literally what the new situation amounts to, Now, the party via Geely is the largest holder of Volvo shares, meaning the party is the largest stakeholder of the Mack brand. When one buys a Mack brand truck now, you are sending a portion of your money to the CCP. No rocket science here. How does everyone feel about that? Our government, the DOJ, should never have authorized the sale of our iconic Mack Trucks to foreign aggressors. Only Americans care about America, and American business. Foreign aggressors only want to profit in the US......their allegiance does not lie within our shores.

  11. Heavy Duty Trucking (HDT) / January 24, 2018 The Teamsters union is seeking to prevent UPS from using driverless vehicles or drones to deliver packages, the latter of which the parcel delivery company had already performed a number of tests on, reports the Wall Street Journal. The labor union also wants UPS to ban deliveries after 9 p.m. and add an additional 10,000 workers, according to the Wall Street Journal. In February 2017, UPS successfully tested a drone that launches from atop one of its package cars. This system is designed to autonomously deliver a package while the truck is driven on a route. Previously, UPS and the Teamsters union recently clashed in December 2017 about the parcel delivery company's decision to bumping up driver workweeks to accomodate holiday deliveries, according to the Atlanta Business Chronicle. The Teamsters and UPS are currently negotiating one of the largest collective bargaining agreements in the U.S., which covers around 260,000 UPS employees and expires in July, reports The Wall Street Journal. A recent study by C.J. Driscoll & Associates found the last leg of delivery between distribution centers and buyers has become an issue for e-commerce, which accounted for 11.7% of retail sales in 2016, versus 10.5% in 2015. In October 2017, the Trump Administration moved to establish a coherent federal policy governing the use of drones in delivery applications, according to a presidential memorandum issued last October.

  13. Prime Mover Magazine / January 25, 2018 Hino Team Suguwara’s success in the Dakar Rally has continued with a record ninth consecutive class victory in the 2018 event. After 15 days and 14 stages of competition, Hino Team Suguwara’s Car 2 delivered a stunning performance to win the highly-competitive Under 10-litre class and finish sixth overall. Speaking at the finish line where he greeted the competitors, Hino Motors Chairman, Yasuhiko Ichihashi said: “I am very happy that the team was able to fulfil their goal of winning their ninth straight win in the Under 10-litre Class." Driver of Car 2, Teruhito Sugawara, enjoyed the challenges of the difficult course which traversed many areas he hadn’t previously raced in. “This was the 20th Dakar Rally for me personally, and I'm glad that we were able to achieve the results that we aimed for," Sugawara said. “I think we were able to make the best of our current potential so it was very satisfying in that respect too.” Hino Australia National Marketing Manager, Dimitri Andreatidis, congratulated the team on its success: “Sixth place against competitors with larger trucks is a significant achievement and one that we at Hino Australia are very proud of, especially as it is two places higher than last year. “The reliability of the Hino team once again shone through with a ninth consecutive class victory.” Both of the Hino Dakar Rally 500 Series vehicles used an enhanced version of the Hino A09C 6 cylinder engine, which is available as an option in the 500 Series Wide Cab trucks in Australia. The two 2018 Dakar Rally Hino trucks included the 8,866cm3 direct injection turbocharged and intercooled engine matched to a six-speed direct drive gearbox with secondary transmission, two-speed transfer and a part time all- wheel drive (AWD) feature in Car 1 and full time AWD in Car 2. The 40th Dakar Rally finished on 20 January after 15 challenging days that saw competitors race through Peru, Bolivia and Argentina. .
  14. Diesel News Australia / January 25, 2018 Is this the truck of the future? Or is it the truck of the past? It is, in fact, a futuristic prototype truck which was built well over ten years ago. The Colani TUM Supertruck of 2006 was dubbed the ‘Innotruck’ and took the separated driving compartment concept to new levels. A powered aerodynamic lower module contained all the mechanicals of a conventional prime mover including a fifth wheel. On top of this sat the semi-trailer that included a cab integrated into the trailer’s nose, reduced to a conical glass canopy projected out from the streamlined trailer body rather like the Concorde’s nose. The concept included the race car-like power module, the semi trailer and a third full trailer. It was designed and built in cooperation with a team from the Technical University Munich (TUM) and was intended as a demonstration vehicle with a meeting room occupying the trailer behind the pointed single seat driving compartment. Entry and exit from the driving compartment was achieved by sliding the nose, windshield and forward windows forward for the driver to step up and into the driving seat. .

  16. IVECO Trucks Australia / January 25, 2018 IVECO Australia has announced an additional power rating for INTERNATIONAL® ProStar® models, providing buyers with a new 600 horsepower (447 kW) / 2,050 lb.ft (2,779 Nm) option, along with the existing 550 horsepower (410 kW) / 1,850 lb.ft variant (2,508 Nm) rating. The additional power has been achieved via calibration changes to the ProStar’s 15 litre Cummins X15 engine, in a successful joint project between INTERNATIONAL’s Australian engineers and the team at Cummins South Pacific. INTERNATIONAL® Engineering Manager, Adrian Wright, said the additional output rating was a logical step in offering prospective customers a second power option if the application required it. “For the initial development program, we focused on the 550 horsepower / 1,850 lb.ft rating, as this was the most commonly specified in the B-Double conventional market segment,” Mr Wright said, “but it was always our plan to look at the 600 horsepower rating at a later stage. “With increased ProStar® sales activity and a growing enquiry rate on both 550 and 600 horsepower ratings, the timing has worked well.” In bringing the 600 horsepower option to market, Mr Wright said that there was close collaboration between INTERNATIONAL’s local engineering team and Cummins South Pacific. “We re-evaluated a full production spec truck and tested it extensively both on the road and on the dyno,” he said. “The truck performed exceptionally well and easily met all of Cummins’ stringent requirements for Australian heavy haul applications. “The 550 horsepower engine is a strong performer but the additional torque of the 600 horsepower engine will allow the truck to hold a higher gear for longer which can be advantageous for certain applications and can even help save fuel in some circumstances.” Both engine ratings can be specified across the entire ProStar range encompassing ‘Tipper’, ‘Day cab’, ‘Extended cab’ and ‘Sleeper cab’ models, with either the Eaton 18-speed manual transmission or Eaton’s clever ‘UltraShift Plus’ 18-speed automated manual. .
  17. IVECO Trucks Australia / January 22, 2018 Leading concrete and construction products company ACM, is looking to capitalise on Melbourne’s booming western suburbs with the opening of a new batching plant in Rockbank and the acquisition of 10 new ACCO 8x4 agitators to service customers in the region. Established in 2009, ACM now operate 38 trucks from two sites with a key differentiator for the company being its strong commitment to sustainability – the philosophy is captured in its company tagline ‘Redefining Green’. To achieve this, the business has a number of initiatives in place to minimise its environmental impact, these include collection of stormwater for use in its concrete and crushing plants, the use of recycled rock and concrete in making its concrete aggregates, the adoption of dust suppression systems at all plants and the use of ‘E-Cretetm’, a replacement for conventional concrete that delivers up to 80 per cent less carbon output than traditional concrete. Fittingly, ACM has chosen a bright green livery for its fleet that is hard to miss on the road or at the building site, further drawing attention to the company’s strong environmental aspirations. The new ACCOs are all equipped with 7.4 cubic metre bowls and are an ideal fit to service a range of customers across civil, residential and commercial sectors, according to ACM General Manager, Digby Crawford. “The great thing about the ACCOs is that they are fit for purpose – the trucks and all of the driveline componentry is proven, reliable and long lasting,” he said. “Maintenance on the trucks and availability of parts is another benefit, you can find replacement parts everywhere, which minimises the likelihood of any downtime. “Another attractive aspect of the ACCOs was the availability of Electronic Stability Control which is important in this application where the load has a higher centre of gravity.” Although the ACCOs were a well credentialed concrete truck on paper, their selection was by no means a given, with Digby undertaking extensive research before finally settling on the IVECOs. “We looked closely at five different brand trucks all up, but in the end the ACCO had the best all-round package,” Digby said. “The combination of low tare weight, industry standard components, cab over design which allowed us to better manoeuvre in confined spaces and superior serviceability won over.” The trucks all feature 340 hp engines with 1500 Nm of torque and are coupled to 6-speed full automatic transmissions, and while the vehicles will only cover approximately 20,000 kilometres per year they will face high running hours. Suspension on the trucks is handled via rear rubber block, while up front the trucks run integrated air suspension, a combination that has drawn praise from ACM drivers. “The drivers are complimentary of the ACCOs, they drive well and in particular they mention that the ride is very smooth and comfortable,” Digby said. “The Rockbank facility and the 10 new ACCO agitators are important components of ACM’s future growth and are helping us ‘Redefining Green’. “We also have another plant under construction in Clyde (South East Melbourne) which is due to open in early 2018 – a further 10 ACCOs have been ordered for this site.” Photo gallery - https://www.iveco.com.au/whatson/ten-new-iveco-accos-cement-acm-expansion-with-further-10-on-order .

  20. FCA posts $1 billion Q4 profit, predicting 'strong likelihood we'll outperform Ford in 2018' Larry Vellequette, Automotive News / January 25, 2018 Fiat Chrysler Automobiles reiterated its plan to be in a net cash position by midyear and hit aggressive financial targets for 2018 set four years ago -- including nearly $10.9 billion of adjusted earnings before interest and taxes -- as the automaker prepares to transition to a new leader with the coming retirement of CEO Sergio Marchionne. And in comments to analysts, Marchionne said there is a "strong likelihood we'll outperform Ford in 2018." FCA said Thursday its fourth-quarter earnings before interest and taxes rose 22 percent to more than $2.37 billion. Net profit nearly doubled to $1 billion. Total revenue in the quarter fell 3 percent to $36.11 billion. Improving margins in North America -- which rose half a percentage point to 7.9 percent -- will mean $5,500 profit-sharing checks on average for UAW members, up from $5,000 a year earlier, FCA said. These payouts will be on top of a $2,000 bonus paid to all U.S. workers, except top executives, related to U.S. corporate tax cuts. Changes in U.S. tax law are projected to save the company $1 billion a year. FCA cut its industrial debt almost in half last year, to 2.39 billion euros ($2.97 billion). Marchionne and CFO Richard Palmer said the company expected to have more cash on hand than debt by midyear, the first time since Fiat S.p.A. acquired the formerly bankrupt Chrysler in 2009. Shares in FCA rose 0.75 percent to close at $24.32 on Thursday. Comments to analysts In comments to analysts, Marchionne said the automaker would lay out its 2018-22 business plan for analysts at an event June 1 in Balocco, Italy, but would not name his successor until after that event. Marchionne plans to retire early next year after seeing the business plan through 2018 to completion. The CEO, who has run Fiat since 2004, has said his successor will come from the ranks of the automaker's global executive council. In other comments, Marchionne said: Despite plans to keep the previous-generation Ram 1500 pickup in production for at least a year to answer demand from commercial fleet customers, the CEO said he was "not interested in starting a share war in the United States" with Ford or General Motors in the pickup segment. "That's not the objective," Marchionne said. The FCA board will decide in February whether to spin off or sell off Magneti Marelli and its other components businesses. Since no other automaker expressed interest in forming a partnership with FCA, the company's improved balance sheet will mean "we're going to keep running our business and running our business hard," Marchionne said. "Given the parameters of this industry, FCA is well-positioned to be a top performer, and that's all I care about." While the company will be well short of the 7 million vehicles it projected in 2014 to sell in 2018, the financial targets will be achievable because of unforeseen levels of profitability from Maserati, Jeep and Ram. But, Marchionne warned, much of 2018's performance rests on properly executing the launches of the redesigned Ram 1500 and Jeep Wrangler. "I think the biggest risk ... is that we screw up all those launches and we can't deliver the volumes. That's the real issue -- that we can't make it." Additional manufacturing capacity brought about because of its reindustrialization plan in North America could mean as many as 50,000 additional Ram 1500 pickups and 60,000 Wranglers annually on an ongoing basis, once those recently launched products are fully ramped up. Marchionne said the additional Wrangler capacity would allow FCA to export the vehicle in greater numbers instead of limiting that global distribution to satisfy demand in North America. Both Fiat's and Chrysler's previous dire financial straits embedded fiscal discipline deep into the DNA of the automaker's top management. That should prevent it from spending wildly when times are good. "One of the things that came along with being poor ... is that you learn how to do with less. I have not forgotten, and no one on the leadership team has forgotten, what it was like." Alfa Romeo will again not be profitable in 2018, but it will return to Formula One racing after his retirement as the resurrected brand continues to grow beyond beyond its current lineup. "We're still building the brand, but we need more volume." Bloomberg contributed to this report. .
  21. You already know that just "replacing the rails from the cab back" is not the right way to go. We don't need to tell you.
  22. I’m curious if rails are even still available from Volvo, and the price. Volvo policy is to cut parts availability at 15 years, or charge a premium.
  23. Ford will disclose product cuts later this year Reuters/Bloomberg / January 25, 2018 Ford Motor Co. will disclose details later this year of its investment shift to SUVs and crossovers from passenger cars. On Jan. 17, Ford said it will scale back its car offerings and offer far fewer iterations of models that survive as it seeks to become leaner and nimbler, and improve profit margins. Reporting fourth-quarter and 2017 earnings Wednesday CEO Jim Hackett declined to offer more details to frustrated analysts, saying only that he would share details later this year. Ford is considering where the biggest opportunities are, he said. Executives have said that Ford is implementing business practices focused around Hackett’s mantra of "smart vehicles for a smart world." This includes $14 billion in costs cuts, simplifying orderable products, and tailoring its model lineup to higher-margin segments for different parts of the world. The investment shift means Ford will focus on performance SUVs and "authentic off-roaders" where the automaker can get higher profits, Jim Farley, president of global markets, said earlier this month. Ford expects its utility-vehicle mix will increase 10 percentage points over the next couple of years, while its car portfolio will shrink about 10 percentage points, the company said on Jan. 17. On Wednesday, Chief Financial Officer Bob Shanks said that Ford isn’t as fit as its peers, and that is stopping it from achieving its desired profit margins of around 8 percent. Ford’s 2017 pretax profits fell 19 percent to $8.4 billion, reducing its operating profit margin to 5 percent from 6.7 percent in 2016. Fourth-quarter adjusted pretax profits fell 19 percent to $1.7 billion due to higher steel and aluminum prices, as well as adverse currency rates. In Europe, Ford's pretax profit slid 66 percent to $56 million in the fourth quarter and fell 81 percent to $234 million for 2017. Most of the full-year drop was attributed to Brexit-related charges, as well as higher commodity and warranty costs. Shanks said Ford's revenue will be bolstered by the launches of 23 new vehicles globally this year, up from 11 last year. Ford's key upcoming launch in Europe is the new Focus compact hatchback, which arrives later this year. Ford is also preparing an ambitious plan to roll out robot taxis and driverless delivery vehicles by 2021.
  24. Solid Reductant Storage for SCR Systems W. Addy Majewski, DieselNet / January 2017 SCR systems that store a solid ammonia precursor and deliver gaseous ammonia reductant to the SCR catalyst allow for improved low temperature performance compared with urea-SCR systems. Two main groups of materials that can store ammonia and release it on heating include metal chloride ammines and ammonium salts. Solid SCR systems under development utilize strontium ammine chloride or ammonium carbamate for ammonia storage. Introduction Selective catalytic reduction (SCR) has been introduced to control NOx emissions from a range of diesel engines, including light- and heavy-duty highway engines and nonroad diesel engines. Water-based, 32.5% solution of urea—known as AdBlue® in Europe and diesel exhaust fluid (DEF) in North America—has been used as the source of ammonia in practically all SCR systems for diesel engines. Urea solutions, however, show a number of disadvantages, especially during low temperature operation such as cold start of slow urban driving. A minimum exhaust gas temperature of about 200°C is required to ensure a complete decomposition and hydrolysis of urea to ammonia. If urea is dosed at insufficient exhaust temperatures, deposits are formed over the catalyst and in the exhaust system. Creating uniform ammonia distributions is also problematic, typically requiring a static mixer and/or a certain minimum length of piping between the urea injection point and the catalyst inlet, which complicates exhaust packaging. An additional disadvantage of AdBlue/DEF is its freezing point of -11°C, necessitating the use of heating in SCR systems in cold climates. A number of alternative ammonia storage materials have been identified to address the issues with urea [Fulks 2009]. The alternative ammonia storage and delivery concepts that attract most attention are those that utilize solid materials—such as ammonium salts or metal ammines—which contain ammonia and release ammonia gas when heated. In this type of a solid SCR system, a cartridge or canister with a solid material—an ammonia precursor or a substance with absorbed ammonia—is carried on the vehicle. During vehicle operation, the material is heated to release pressurized ammonia gas, which is metered into the exhaust gas using a control valve. Once the cartridge becomes depleted, it has to be removed from the vehicle and re-charged with ammonia using specialized equipment. In solid SCR systems, gaseous ammonia can be introduced into the exhaust gas at any temperature, including slow urban driving or engine idle conditions. If SCR catalysts with good low-temperature activity are used, NOx can be reduced at temperatures significantly below 200°C. The performance improvement due to the use of gaseous ammonia as the reductant is illustrated in Figure 1 [Karkamkar 2016]. However, it should be noted that solid SCR technologies cannot address low temperature SCR issues that are rooted in the chemistry of ammonia, rather than urea. Such an issue is the formation of ammonium nitrate (NH4NO3) via reactions between NO2 and NH3 at temperatures below 200°C. While examples of SCR operation with continuous ammonia dosing during urban driving were reported in the literature [Johannessen 2010], continuous low temperature SCR operation may not always be possible depending on the exact temperature and NO2 concentration. In SCR systems with advanced control algorithms, the amount of deposits (such as NH4NO3) is calculated as a function of the amount of injected reductant and the operating conditions, and reductant dosing is stopped once a maximum allowed deposit mass has been reached. Hence, while solid SCR systems can help meet NOx emission limits in testing over regulatory test cycles with low temperatures—such as the chassis FTP schedule—they still may face limits in reducing NOx in applications characterized by prolonged low exhaust temperature operation. Commercial Viability & Infrastructure. The scope of commercial applicability of solid SCR systems will depend on several factors—including their cost competitiveness with urea-SCR systems. At least two solid SCR systems have been under development: (1) a metal ammine chloride system by Amminex and (2) an ammonium carbamate system by FEV/Tenneco. A limiting factor in the adoption of solid SCR is the lack of infrastructure for the replacement and re-charging with ammonia of used cartridges. Compared to urea-SCR, the logistics are more complex with solid SCR, as both empty and re-charged cartridges need to be handled. A number of types and sizes of cartridges may be also envisioned in solid SCR systems, depending on the type and size of vehicle. Therefore, solid SCR seems to be most suitable—at least in the initial period—for vehicles operated within a limited range. Urban delivery trucks or buses, for example, could be supplied with cartridges within a geographically limited distribution network. If the commercial reach of solid SCR widens, infrastructure will have to be developed to supply and recharge/recycle ammonia storage cartridges. In the case of metal ammine-based technologies—where the cartridges are charged using pure, anhydrous ammonia—the necessary infrastructure could be built based on the existing ammonia distribution network [Johannessen 2010]. The cartridges could be recharged with ammonia in recharge stations located near ammonia distribution centers. Several industrial gas suppliers operate extensive networks of ammonia ‘hubs’ and each of these ‘hubs’ may potentially serve as the basis for a recharge station. In an expansion scenario, solid ammonia cartridges can be envisioned to be handled in a similar manner to propane bottles for end-user applications, such as barbecues. End-users would not have to consider the fate of a used solid ammonia storage cartridge—it would be handled by professional organizations that would control the logistics, recharge and quality assurance. It may be noted that solid ammonia storage also shows certain advantages compared to the urea infrastructure: no multiple quality assurance steps are required in the reductant supply chain. With a well-defined solid cartridge that has been quality assured from production or recharge, the content of the unit will not be exposed to the surroundings and will not degrade under any—hot or freezing—climatic conditions.
  25. Solid Ammonium SCR System for Control of Diesel NOx Emissions SAE / January 14, 2017 One of most effective NOx control technology of modern diesel engines is SCR with ammonia. Current NOx reduction systems are designed to use a solution of urea dissolved in water as a source of ammonia. However, the liquid urea systems have technical difficulties, such as a freezing point below −11°C and solid deposit formation in the exhaust temperature below 200°C. The objective of this study is to investigate the possibility of a new ammonia generation system that uses low-cost solid ammonium salt, such as solid urea and ammonium carbonate. The result shows that ammonium carbonate is more suitable than solid urea because of low decomposition temperature and no change to the other ammonium salt during the decomposition process. This paper also shows the NOx reduction capability of the new ammonia delivery system that uses ammonium carbonate.
