Mack Technician

If its a 2-3 code for the truck its the intake Air Sensor. The ECU sets the code when the intake air sensor signal voltage goes below 0.4 volts for more than two seconds. If the signal voltage returns, and is between 0.4 and 4.5 volts, for more than 2 seconds, the light goes out and the code is inactive.

Check your sensor. It should be.....

9,300 ohms at 32 degrees F (set in fridge)

200 ohms at 194 degrees F (in oven)

The current crop of seat warmers seem to be of the mind that only a Pete or KW is a "real truckers truck" same group that runs to buy the GM pick up with the 9 function tailgate just because of the hype. My two AM General power units and my Marmon will do everything the new units do except two things. No computer and emissions issues and I am not allowed to go into Cali.Big whoop.

My buddy's son is still in seat warmer mode. I sold Dad on the idea of picking up a CV713 for the woods and lowboy, he bought one and likes it. First born son protested because he wanted a Pete 379. "Why" asked Dad. "More visibility" said son. We all had a pretty good laugh at his expense. Hard to score Facebook points in a CV713 was the bigger issue.

You guys attending the 2019 Moxie Festival?

https://moxiefestival.com/

The Moxie congress, Lobster dinners with the Freemasons, Moxie comedy, Parades and live entertainment !!!!!...…… My bucket list just got two lines longer. Something cultural about that hometown scene, family friendly appeal. If it was Wisconsin they would all be drinking beer, nothing against it, but they wouldn't celebrate a cultural icon like a soda with history unless it had liver teasers in it.  

So now what? We need Farmers Brewery Root Beer in the East and Moxie in the middle?

Bandit and Snowman got bootleg Coors from Texarkana to Atlanta. Guess that puts you in the Smiley Face M917 and me running blocker in my "Friends of Jesus" Dodge Caravan?

Thanks.I will do that per mack service bulletin SB-224-004 .which you provided in a previous thread.

 

Forget i’m Preaching to the CV choir. 😁

Anything’s possible. Your running ultra low sulfur diesel in a truck built before/or around when “dry” fuel was introduced. No telling to what degree they engineered it using new lubricity standards for post 06’ equipment? 

Be curious to see what you find......

This is my AI book. Pipe a 1/4” airline  X 1/8”NPT into the port closest to my thumb (but at front of engine ) with a 0-100 gauge. It says supply and return, but you know that doesn’t matter since they discontinued the center oring on the EUP. Either port works. They run a drill through the entire length of block and cap both drilling’s on each end with 4 Allen pipe plug.

Some union boy got upset that you were working so he dumped metal shavings in your fuel. 

Kidding, but it wouldn't be the first time. My cousin got metal shavings in the engine oil of all his equipment on a job once.  Courtesy of union pricks. And they wonder why the rest of us don't like them, and want nothing to do with them.

My thought too, but not kidding. Those systems don’t make shavings, they make microns of free agent debris. If the filings are in the secondary filter they would have to have come out of the fuel transfer section however.

Don’t mess with a lot of engine rolling.

Make sure filters are still full. Crack a line on output side of lift pump. Place a plastic garbage bag on tank opening with hands sealing bag to opening. Stick air nozzle in and pressure fuel through pump and fasten line while your flowing fuel. Should be able to operate the hand primer for rest of operation. Crack fuel overflow valve and turn engine over to confirm system has flow. Crack all lines and position throttle full fuel, make sure shutoff is positioned for run and crank. Should be fuel, otherwise Theakerstwo scenario may be playing out.

The justice system treats the criminals 100% better than the elderly and veterans. We give the convicts  health, education, internet, cable t.v., 3 square meals and now in many states felons will get their voting rights back. (NOT a right it is a privilege)   What we give the elderly and many vets is a couple of bucks to pay for their healthcare and some cat food. A few politicians on the full term abortion band wagon are also pushing for the euthanasia of the elderly with Alzheimer's,  Dementia and terminal issues to unburden the healthcare system. A short step to target other "burdens on society".

We  treat the illegals better than the old and vets.

A good gauge on society is how they take care of the old and their veterans. Where do you think we stand  by that criteria?

Gets worse. Old fella at work was telling me a story about his son-in-law. Son-in-law worked at the prison, Black River Falls Correctional. They brought in an LGBTQRSTYBlah blah-whatever person. The person was in the middle of Hormone treatments to become a woman and had some reconstruction already underway. The prison system was forced to complete the surgical procedures and hormone treatments to finish the job. Oops, now he’s a girl, can’t stay here for the sake of prison rape. Get another judge and put her in his own block till we figure something out. The whole thing is madness. 

One of those events you can read and watch documentaries about, but won’t fully comprehend unless you jumped out of the landing craft.

Over memorial weekend my mother-in-law read to the family out of her dad’s journal and letters home.  Both of my wife’s grandfathers were in the Iwo Jima invasion. One was on the water in the USS Brush working sonar during the escort and bombardment. The other was Marines Infantry in the invasion. They certainly were a great generation. The Marine Grandfather made a comment about cranking a generator radio for two hours straight while they were calling artillery. He was losing strength in his arms to keep it going and his replacement was apparently KIA. He told his commander he needed help. The commander said “take him (wife’s grandfather) over there and shoot him, then find me a replacement”. He kept cranking. Eventually the horn operator made a bad artillery call and was pulled. Grandad was told now to call artillery and keep cranking. 

Seems like they were young, full of piss’n vinegar’n fight and too immersed in the middle of complete chaos to think about how dangerous it was.

Volvo pull out of NA and sell Mack to Cummins,  Hendrickson, Oskosh, Deere or Cat.  

Wouldn’t that be something! My vote is Oshkosh.

Holed up at home today.....forgive me if I’m chatty.....

Writings on the wall.....”We need money”

I got an E-mail from our district Volvo rep two weeks ago. Volvo is dropping free Prosis subscriptions next month. He sent a chart to me that had a graduated ramp of cost relative to how many specific Volvo models we own. By the time you get to a Prosis subscription that can cover 10 or more different Volvo models your hitting $2,000 dollars per year. That’s getting right down to business coming off a free subscription and not including the Tech Tool subscription you also need.

So now every construction company has moved to Deere or Cat where they can get a full line of equipment. 

Cat is a real darling to their customers, much more so even than JDeere. You buy a piece of Cat equipment and they send a mechanic to inspect it once every three months for two years, a free (purchased) service, free road call. Road tech would hand me the list and say “If you want a quote call us, or “this is how I recommend you fix it”...”any questions before I go”...etc. They provide a low cost software subscription that does everything but break a “lock-up”. Lock out=you dummy, the ash load is 140% and your still driving it, now you need a code to unlock it. The day they delivered our first Cat loader they had an IT guy installing our Electronic Technician before the salesman left the front office. 

Volvo restricts the ability to do any machine calibrations. When it was brought up in debate the Volvo rep said “its for your own good, your calibration settings are being preserved in a main frame. If your machine gets hit by lightning or your modules fail Volvo will have all calibrations that have ever been made and will load them directly back to your machine”. The hole in the story is that we are on the main frame, at our shop, with our TechTool. It opens to Volvo “central system” every log in, we had to install WiFi in our building specifically to run it. In fact it took 5 months to get Prosis installed securely because the Corporation’s firewalls considered it too deep of a working connectivity to an outside entity. 

Complaining aside, all in all, the cost per hour is low with VOE. They have some chronic issues, but so far are relatively cheap fixes.

The bolts riding the debarker conveyor look like 8’. My guess is that grapple works well on longer saw cut bolts.

Lock screen on 15 seconds. Chain has 7 links per lamination at 1/4” thick. So 14 total, pretty heavy and they bend laterally less than your average bike chain. Can also see the bolt on lead wear edges@15. Those are slick. It use to take our guys 4-6 hours to remove and weld new lips on. Liehberr changed over to those and we can do a set it 15 minutes. Constantly digging against concrete to pick sticks so hard on them. Before you got three weeks on a set, now you go three weeks, flip them over and refasten. Added one extra week of usability. Like Liehberr does, they create something slick and realize it. One side of those bolt on lips cost $1,300. So $2,600 per month just to keep wear lips on the bucket. Plus two stud kits at $75 per. Our machinists built them for about $250 per side with man hours. 

Liehberr price gouging goes overboard sometimes. Just yesterday I ran out of Liehberr OEM fuel filters. Thought “shoot, I’ve never used a NAPA fuel filter on this engine”. I sometimes use a NAPA for first stage(primary), but never final stage(secondary). Too much $$ downstream of the final fuel filter to take chances. I’m ok if a transfer pump gets a spot of dirt, but not the high pressure system. I ordered a replacement filter from NAPA because we couldn’t wait and, hey, look at that....pulled a German made Mann Hummel out of the box. Talked to my rep and he told me “Oh yeah, Mann Hummel bought Affinia(Wix) a while back”. NAPA is vending the exact OEM Liehberr fuel filter($62.56 from dealership) for $22.00. 

Liehberr sure has a broad mind for inventing new mouse traps. Dig that forward protection articulating up with the bundling blade lowering to push piles. Grapple has a narrow, high, basket for stick stability. 

It wouldn’t work in snow country with one wheel hydrostatic drive. Even on concrete. In our world frozen wood would slide through the narrow jaws and you wouldn’t be unable to clean up the dropped pile. Operator could call for a swing boom operator to pick up stick mess during the day, but at night he would have to stop operations and clean it up himself with a different machine. 

The L180HL we use now has self-closing sequenced hydraulic tongs that lock the wood into the grapple upon jaw closure instead of a free-weighted chain like this Liehberr. Still lose a grapple full now and then. 

Never heard of it?

Did you figure this issue out or still chasing?

Isn’t it odd that career politicians have a salary of about $300,000 yet their NET worth is in the millions and billions. I wonder where all that extra money comes from. 🤔

"Speeches Boss, Honestly, I just gave a bunch of really good speeches".

Hillary and Bill made $153,000,000 for speeches in 15 years..... AKA-Pandering for political favors via grossly overpaid speeches.   

The “R” in the dash is inside a branch circuit which goes from fuse 42 to the back-up switch then splits. One split goes to the dash. One split goes to a fork-split into reverse power relay and back-up lights. Chances are a bad ground or failing bulb. These dashes are notorious for bad grounds, but usually you have a lot of stuff going wrong in the dash, not just a bulb flicker.

Oil pressure for the engine is all being calculated off a single 3 wire sensor lined into the ECM. ECM is sending that info on a J1939 CAN line to the VCU and dash. If your dash is agreeing with(simultaneous with) the shutdown you could be experiencing a sensor wire rub/break between the sensor and the ECU. You still need the manual gauge installed during a drop-out event to make certain it’s not something of a real threat to your engine. You prove it’s not a real pressure loss then have the dealer shut off your “protection shutdown” feature temporarily till you get it fixed. It’s unsafe to have unwarranted engine kills. 

And in case it's running poorly as a 2006 does...…..click on...

Wonder what kinds mpg he gets...

I'd guess his up-time is off the map in comparison to the final tier 4's and some carriers want to hire him...…...especially since he will do East Coast.

I'm zooming in on the DM with the 4 tier front hitch thinking I was going to read the plaque...…..in Flemish!!!!  What were they tethering 4-ways?

Cool Pics!

Not to hijack your post, but I'm throwing one in. Pretty unit sitting outside our shop this morning.

Good, install the sensor and you will have exclusive rights to wiring into it. Pay attention to whether you want normally open or normally closed. 

See attached.....

Leave the light circuit alone and break in at the sensor manifold.

Not to derail this thread, but would a guy gain anything by just changing the manifold only?

Mackvette gained a little snap, but lost 2 PSI top boost by installing the larger manifold and S400 turbo (with no injector swap). Once he swapped injectors it performed above the line. 

 I’d wager manifold only will maintain with a possible slight rise in boost and EGTemp. It would set the stage for a future upgrade.

Does it turn over. You need to include more information?

You need to go to PAI industries. They supply aftermarket for Mack. You can phone order from any PAI dealership.

If I can make a suggestion against stock (click on attached thread for other parts including exhaust manifold on page 5). 

You need these for your truck.......

Ends are 21090679 (104GC5164M-old number) $284.06, of which you need 2. 

Center is a 21090730, $203.99 (Both 104GC5165M3 (high temp center) and 104GC5165M (regular application) supersede to same number.... 21090730).
