Ain't nothing left to sell ! A Cab and hood would be a tough sell to anyone in my mind! Hollowed OUT!

Gutted is a more fitting term , like they did to White. Difference was that White had enough bones to build back up some what, Villy Voodenshoe Corp even ate the dogs bones.

Volvo gave MACK a sour reputation with poor choices for Vocational units, limited engine sizes , reliability issues in the MP series injectors and poor warranty support. Go to your local Truck Group Dealer and the sales reps push PAACAR or Volvo and discourage any interest in a Mack thats not"off the shelf" .  One black mark voids all of the pluses.

Adapt the John Deere 13.5 liter engine and paint it Gold.  I just calculated the hours of our oldest 13.5. It would have the equivalent of 1,370,000 highway miles on the original. They can top over 600HP. It burns a gallon every every 300 hours, but at 34,000 hours that ain’t too shabby.

Great engine, but can it pass EPA highway emissions standards?

Off Road has caught up since since OTR lingered in final 4. So DEF and SCR equipped. 

Had a rookie operator fill the 13.5 engine crankcase with diesel fuel and hammer on it for 40 minutes before his trainer figured out what he had done via conversation. It pitted (starved) one overhead cam lobe at the end of the dinner table. Sent a pic to reman center. Told them the hours and what I wanted to do. They said “Go for it, engine’s old enough to be considered spent for reman, won’t hurt anything as far as future core damage”. I put a new roller arm on and ran it. That was 5K hours ago. Tough 🍪 cookie. 

Not much aluminum on the motor. Not built with payload savings in mind like the Mack E platform was. Cast iron intake, cast bell, built for counterweight at rear of machines.

Yup even caught up to the farming equipment with this crap.. it would not be so bad if they could make it reliable !

Can't blame Volvo, can't blame Renault, can't blame Signal but you can blame the Mack board of directors. Nearsighted and gutless, they took the easy way out. White went bankrupt fair and square though totally reckless ruining White, Reo, Sterling, Diamond-T, Euclid, and Autocar almost.

Could consider this the new maxidyne gold tone. Great to see they got rid of the compounding turbo, damn things kept breaking all the exhaust studs like the Mack AC use to. Too much VGT turbo weight. They even dumped the VGT and installed a waste gate. Different block than 13.5 base engine. Oil pan isn't going to work.

Check out the EGR flow from right to the left side single EGR meter valve. Keeping in mind the water pump is lower right side driven by the small belt. The flow through housing makes you scratch your head. First it looks like a EGR charger system, its not, but maybe a second cooling stage.

Is this engine common rail injection?

I'm guessing the compound is added for emissions compliance differences between stationary generators and construction/Ag.

The Deere and the Bulldog, two American icons coming together to recreate the  perfect 700 HP heavy truck....... guy can dream. Deere is in good fellowship with ZF on the heavy off road for most of their transmissions, have them construct a transmission.

Building dependable things is not good for business ! You need to sell parts and service! Best way to do that is build cheap shit! with cheap ass sensors and parts!

[kscarbel2]

The more I think about this, i.e. Volvo's termination of Mack-designed Maxitorque transmissions, the more disgusted I feel.

Note the webpage while you still can.......obviously it isn't long for this world.

I have been around macks since 1965 and i have found that they used a lot of engineering and did their home work.I hate seeing this going to waste.

We’re pretty happy with ours. We have the JD Service Advisor software and the turn arounds have been fast.

HHmm, Available up to 2100ft/lb....

Not here It isn't.... Capped at 1800ft/lb.

which limits it to the 435hp Granite (Or at least that's according to the Mack Australia website) 18 months (or so) ago I got a quote an a New Granite Dealer pointblank refused to quote on e with a mack 'Box..

In out fleet of 25 trucks , all are 2013 or newer CXU’s or Anthems and all have T-310 trans and Mack rears . To be honest, every one of our Mack transmissions have been back to the dealership ( except the newest ones ) al least once and most twice. All having synchronizer problems. 25% of the problem is driver abuse/ improper range shifting. The other 75%  are loose range shift fork set screws or loose rear yoke bolts . Years ago Mack used safety wire on the fork set screws , if they started doing that again it would help out a lot . And if they would use red  Loctite or redesign the yoke bolt it would save a lot of down time.  The M-Drive automatic would work great in our live haul trucks. Our feed trucks need multiple PTO pumps and massive plumbing to the trailer. We have looked into the M-Drive and I just don’t think the room is there to rig up all our crap. Sadly we have no say in ordering our trucks . Our corporate sends us what they think we need.

Agree ! When ever we take these apart we use red loctite to reassemble them on any bolts susceptible to coming loose  period! However its only part of the  issue resolved! And they did redesign the output yoke and made it worse! installed  behind  any High torque  engine like the ISX the tail shaft had tappered roller bearings and a crush sleave! That turned out to be another  Big mistake! and now Mack pro  you don't got to worry they won't be able to order any manual tranys ! Probably A good thing!

You would think Volvo's all-knowing engineers in Sweden could remedy loose range shift fork set screws or loose rear yoke bolts.

The M-Drive AMT of course is simply a rebadged Volvo single countershaft I-Shift AMT (ZF's superior AMTs feature a twin countershaft design)

Mack engineers were developing an AMT version of the "world's best" Maxitorque triple countershaft transmissions, but Volvo canned it.

Another evolution of a proven Mack design that was aborted by Volvo and gone to waste

Will Mack still offer manual transmissions from vendor components?

Not for long. Volvo expects all customers to obediently subscribe to their I-Shift AMT (rebadged as M-Drive on Mack brand models).
