Im sure a cummins can squeeze in a new anthem but do you really want a short hood truck with a big big engine under it? I know I would not want that set up just for maintenance reasons alone. I still cant wrap my head around this concept of stuffing a large engine under a small hood. I remember in the 70s when makes built a truck around the engine. Knowing that will one day will come that the need to removed it again or at minimum most of the bolt on parts will need to come off for service. In todays market I see no real need for MACK to only offer a short hood truck and limit its engine options. Mack has even pushed it self out of the Glider market.. I cant name one aftermarket builder that buys mack gliders and builds them to simplified specs for the more hands on trucker or company. I think thats why Pete and KW continue to do better with owner operators. they can still get a long hood and work on stuff with more simplicity.

good catch on keeping it from running away... We had a Cat 6nz turbo fail and priced a new one from Pete and another from a local company to us called J&S dist https://www.google.com/search?client=firefox-b-1&biw=1306&bih=719&ei=NGisWtbpGsrVjwSykJ2QBQ&q=r+s+distributing+minooka+il&oq=R%26S+dist&gs_l=psy-ab.1.3.0l2j0i22i30k1l8.72986.75717.0.78906.8.8.0.0.0.0.114.733.6j2.8.0....0...1.1.64.psy-ab..0.8.731...35i39k1j0i131k1j0i67k1j0i131i67k1j0i20i263k1j0i22i10i30k1.0.8KO6gzEmtzg the one we got from J&S has been going strong for over a year now with no issues and it was 1/2 the price. might try looking for a local rebuild shop or ask around for where others have theres rebuilt at. you will want to wash out the intercooler real good as oil will be pooled in the bottom of it. also pull the air filter and make sure none of the shapnel went that way. it sounds crazy but the wheel metal will go towards the filter some times as soon as the turbo destructs and boost pushes it backwards into the filter.

If its the 8 speed I recall I mostly started a heavy load in 2nd/low then a quick flip it into hi as I move the stick back into 1st. I really disliked this trans because that when loaded you had to use the low side for at least 1 gear. starting out in 1st low and shifting up thru the gears was pointless. when empty I think I would just run 1-2-3-4-5 in hi. I liked the older 2 stick 6 speeds much better

2018 sales to date (feb) Volvo88.3% International 71% KW 57.8% Freightliner 46.4% Pete 37% Mack 8.1%

I would like to know the price tag. If you recall the Titan was over priced and lacked sleeper options....

Volvo did this with reason. But besides that the current Mack models do not offer room under the hood for a cummins just as most others engines would not fit with easeas well. volvo knows if they built a mack truck that people want they would out sell Volvo.

I would only hope so

Mack and cummins have been a long standing partner. I remember lots of Superliners with them and lastly the some of the last CL's. after that I have not seen one under the hood of a Mack. But in today's car and truck world mfg do not like to share or use other peoples stuff. With all the special tools and costly download crap it seams it may be better (for the truck MFG and dealerships) to have their own stuff under the hood just for troubleshooting the endless emission crap and such. Its not like it use to be where you just drop in any diesel and any shop wrench could work on them. I know as a owner this is not the idea case. A owner would like to have engine options for a truck that he is looking to buy. His garage may already have tools or know how to work on cummins and would want to buy a Mack with one under the hood. But that wont happen with volvo running things. This clearly shows that they killed off the low volume sales of their overpriced Titan and now introduce a volvo with the same options. Volvo killed off the mack titan, Mack is bleeding in the refuse and cement market. and they are clearly focused now on fleet spec OTR and day cab chassis with their "new" Anthem line. Yes Mack (volvo) makes a nice truck but just they seams to lack just about everything that long standing Mack customers want to see in a Mack. What I see today is many New customers buying a Mack but what worrys me is I see many longstanding customers forced into dropping them. Volvo is gambling that they will build a new brand of truck and those new people will continue to follow knowing the old customers wont. Seams risky to me sad days from my perspective Trent

if you think it is crank related you might try to bar the engine back and forth and see if the flywheel is moving at the same rate. if you have any slop at all. there is your issue.

I have a 12 speed still waiting to go in behind my 285 with 4.17s I think I figured it would do around 78 MPH flat on the floor

that tag tells me its a 285hp Maxidyne...

I will also make a comment about R models in general . Some were rock solid and drove as smooth as other trucks. then you had some that felt like they spent more time in the air than on the pavement. Most 6 wheeler Macks I drove were well planted to the ground and were smooth driving and running with that extra weight of the dump bed took out any engine vibrations. A superliner with air ride cab was quieter than a standard R model with air ride cab etc...My experience it was the R model tractors was that would tend to vibrate more. What im getting at is these R models all had more vibration than a modern day truck or one made of aluminum. ones opinion of a "bad" vibration may be completely normal to someone else. And without one being there to see or feel it its best to get a few opinions on it.

glad to see all the old pics Rob. Its been a while sense I have seen the old trucks you have

Rob I was under the asumption that all 300+ were of air and water charge cooled. I see yours is just air to air

that has the air and water charge cooler you can see the upper section has the water passage. here is a pic of one up close

from what I recall yes. The most common were in 285 and 315hp. however there were some very early 300 and 350 ratings with the water and air side mount cooler. I have yet to see one of these but many discussions on them coming out just before the front mount intercooling

besides putting a dial on the flywheel as suggested earlier I was going to suggest getting under the truck and watching the flywheel spin in the inspection cover while running to see if its wiggling like the crank is bent. but if your oil samples have been good that kind of rules out any bearing slop you would get with a bad crank. I know you said it has new injectors but one other test you can do fairly simple is to crack open each injector one at a time and see if the shaking goes away. I have never worked on Etec macks but if the injector is firing out of time because of a faulty ECM it can introduce a vibration. shuting down a cyl 1 at a time may be something to try as it don't cost anything. Just throwing out ideas

When the truck is parked in neutral, running... when the vibration comes on and you push in the clutch does the vibration change or go away?

A.) yes the shift pattern you show is correct. B.) that is correct c) ENDT676/676 were all maxidynes. I cant comment if the EM6 and EM7 was the note for a just a maxidyne. When they came out with the 4 valve heads most people I know just called them a E6 / E7 or maxidyne / Econodyne. someone will have to give you a solid answer on this one d) No....the 6 speed mack manual states to use Lo Lo in 1st gear only. Shift patter as follows Lo lo/ 1st, shift the compound into Direct / keeping main in 1st ,2nd,3rd,4th,5th this gives you 6 forward speeds total. that being said the wide rpm range from lo lo/first to direct /1st is most often not possible to do in the slightest bit of soft ground. you simply cant keep the road speed up and match the RPM drop when making the shift into direct. the only other option was to hold Lo lo/1st untill you reached solid pavement but sometimes that was just not practical. So most drivers like myself shifted it this way Lo Lo/ 1st, 2nd ,3rd , shift into direct ,4th , 5th. shifting this way you got your road speed up to about 10 mph before shifting out of lo into direct, I found to be one of the only way to up shift when in soft ground and the load is heavy. it never hurt any of them that I know of.

I got no issues with unions if they stick to their work and keep their nose in their own business.

I had one try and card me in Chicago. Im non union and the job was non union just me on site, I was tarping a load of debris when he walked up. No proper introduction to his name just that he was with the union and asked if I was union and if so to see my card. I said no im sorry im not part of any union so cant help you with that. He asked for my name and I said Im sorry I did not catch your name? He again did not give a name just a union name.. So I politely said ok I think were done here, The company name is on the door, if you have any more questions they can help you. I dont just give out my name to random people just as you dont feel the need to either but Im sure we both understand. I pulled the truck out to the street and walked back and asked again that he please leave the site. He ignored and continued to talk on his cell phone. He again refused my polite but 3rd order to leave. So with him ranting on the phone. I said im closing and and locking the gate. As I started walking back to the truck he started to talk with a different tune. I Said have a great day, I will be notifying the company owner of your refusal to leave the site when asked continually. I will contact the owner of the property as well and I suggest he leave before the building owner gets involved and puts trespassing charges on him. boss later found out who he was and thru connections made sure he did no come back to bother us.... its not what you know its who you know here in the city...

yep. its a shame what the mfg were forced into and what they have force into the market.

ask if they will just put in a E7400 and be done with it. Sorry to hear of these headaches . it should no be like this for anyone.

R700?

looks upside down and backwards?
