And you actually like these junk mf’ers. Head is higher than giraffe nuts and crack more than plaster. I think the IH Cummins motto is “we thrive on bad design”

Not my first choice but a 389 with an MX has 16” between the firewall and the head. Other than the idiotic rear geartrain. Which one would you rather work on?
Local shop has a Mack with Leiffi’s amazing Volvo engine with the state of the art rear gears. Nut came off idler gear and destroyed the air compressor gear. If this was a normal engine it wouldn’t be a big deal. But with rear gear the transmission had to come out and you get to work under the truck.

It isn’t in a cabover either, doesn’t mean it’s a good thing.

The real question should be why do I have to pull the cam to pull the head.

Unless Cummins switched suppliers for the cover, I've never had one that wasn't. Also never had one that didn't have the scissor gear. (Sohc like the one you have pictured)

Just remember that according to Leiffi, that wonderful rear gear train motor would be in a stupidly short cabover. That means after you get the trans out of the way you could sit on the 5th wheel while you work on it.

It's funny I had just told you about doing the cam on a 6.0 without completely removing the cab and now this conversation.

Buddy did an 871 without pulling the radiator but said it wasn’t worth it. Slid the cams forward and got the back bolts, then slid them back to get the front.
The covers on the common rails are slotted but the last 2 we did the nuts needed the impact. Had some the studs break off or spin in the cover. Again it’s idiotic.

Right??!!
I’ve got a 6.4 in here today with a fuel leak on top of the K16. I’ve managed to get to the top of the pump within pulling the turbos, or the cab, but man what a job. I’d like to burn this thing about now....
Anybody that thinks a 6.0 is awful hasn’t owned, or worked on a 6.4.

FWIW, the ISX I did in August had no slots, scissor gear, and the dampener was friction welded in place. It is ridiculous to have to pull the cooling pack to remove the head.

If my only job was to design and build engines and this was the best I could come up with I would quit.

A lot of that stupidness seems intentional to deter guys from doing the work themselves. I'll keep rebuilding my truck until theres nothing left to rebuild. Atleast with my old iron I know how to fix it, you can barely see the engine in these new trucks.

Almost all broken cranks we have seen were from a bad rear axle. Rear gear is a crutch to fix an almost non existent problem by creating 10 more. I can replace my air compressor on an exit ramp in about 20min. Try that on a DD13/15. About like a belt driven water pump, a broken belt on mine is an inconvenience not a tow bill.
I have yet to see how anything is getting better or more reliable with all this latest technology.

I didn't say I liked or agreed with it, just that total harshness and vibration was the reason given for rear gear. They are awful. R&I the CP3 on an M2 is a nightmare for someone my size.
I like my gears to roar right on the cusp of causing psychological damage.
You bring up an interesting point though. I'm curious if bad axle is before or after a dock was rammed.

I believe the idea is for things to not last as long and to be more dificult. If components were actuallt made to last and be easily serviceable there would befar fewer parts sold andif they were easy to change, most would service the stuff themselves. I read on anpther site that cummins makes as much replacement emissions parts as they do on all other components combined. I dont have proof its true but it wouldnt surprise me

I retrofitted a 2 hole SCR catalyst on a 6.7 powered truck mid summer to the tune of $7k because the (intermediate?) sensor is no longer used.
Load of horse **** that should have taken a flash file and a plug

I tend to agree
The ISX was the first engine by Cummins to be 100% designed on a computer, and by a group of yuppies straight out of college to boot. Obviously they had some calculations wrong, hence the gear train randomly exploding on the early models amongst other issues. From there on out it's basically patch work to save the design Honestly they should've gone common rail right off the bat, but Cummins was a little behind the curve.
Remember the coast to coast run they made when promoting the ISX? The trailer behind the truck was packed full of spare parts
