Cummins goes to 1075 lb-ft

[Wiredawg]

Gets bigger with every post! I mean... errr... never mind.

Gotta add up to 19K Lbs GVWR somehowp

So we have “official” sheets showing 400, 420, and 430.

Gotta love modern marketing.

CP3, CP4, or C-3PO?

I think the 420 is correct, and wondered why Chrysler's using the 430 number.

CP3, the access cover for the pump gear's nut is back on the front cover.

Towing our home on wheels West 20 TX right now. It’s 41 out and trans is running 163. If it were 100 the trans on a long 6% grade may get to 170. So that’s just one reason.

Only 34k combined

I agree. No matter the heat in Az, 110+, the AISIN never gets above 170-175. Incredible. The 68 RFE would climb right up to 210 in a heartbeat. Although 210 is not damaging, I'd prefer 175.

I tow heavy a LOT, and the 68 in my truck has never been that hot, not even close.

My 11 HO DRW at 29k combined with 3.42’s never was hot. AMZ/OIL and double deep may have helped.

AISIN simply runs cooler.

Right, they went to the trouble to Photoshop on a 2019+ EGR valve, turbo, water inlet & inlet, etc, too. You got me.

GM says the new cab chassis 3500 gets the full power D-max @ 445/910. That will create a s... storm from the other guys

I wonder if they will turn the wick up in the BinderMax trucks?

 

[Wayne M.]

That Dmax looks scary! So much more intimidating to work on than the Ford 6.7. I mean look at that front accessory drive!
And what’s going on in that hydromatic too?!

Just two belts, one runs the fan, the other runs the accessory drives.
Not sure what you ask about the allison trans, it has an external PTO if that's what you're talking about.

I see 4 idlers on the one belt. That’s quite a liability as they do go bad, especially in salty conditions. So that link belt runs a PTO? I guess. I dunno. I just looks more busy than any other Dmax I ever saw. That’s Ford’s job- to look busy.

I don't think they make a class 3. I don't see any upgrades to the class 4-6.

Anyone know what this gearbox looking thing is on the Ram, rear most drive shaft? Drive shaft retarder or two speed scroll down to about mid page.

That’s an excellent observation. I see a PTO/ hydraulic pump on the trans, but that UFO in the rear driveline?

 

[TFucili]

Quite a contraption.

Very strange, maybe a electric motor booster, can't be a PTO as it would only work while the truck is moving. Click the pic for a large view.

My WAG is it's another PTO transmission?

Looks like it...appears to be an output flange above the outlet to the final little section of driveshaft.

 

[Wiredawg]

Another nice feature added to C&C, disconnect for front axle.

I have extensive experience with class 8 hybrid innovations such as hydraulic launch assist, series/ parallel electric hybridizations etc, and that rear facing motor flange screams to me it’s a mini HLA. The accompanying components aren’t there yet, possibly.
