Hi, this was our truck. It was such a problem child at first but then we got it worked out and fixed, this was some time ago.. Long story short the truck had a burned out fuse for the Allison trans behind the passenger side kick panel, the wiring harness bulkhead had damaged pins, the ECM was burned out, and it had bent push rod tubes. Once we found out it had bent pushrods, we then found out it also have cam damage and knocked out H-rings for the lifters. We ended up replacing the whole engine with a low mileage one we got lucky and found nearby to us.

You’re right! The truck worked for a couple of days since repairing it. No problems since, it was just my paranoia setting in that we broke something else inside. Thank you!

Hey guys I have a CHN with Mack rears that snapped a thru shaft last week on the front/rear. I had spare parts at the shop so I waited till I had time to pull them and just got around to installing today. It seemed pretty simple, the shaft snapped and it pushed the half with the yoke straight out of the aluminum seal flange. After replacing the broken parts I turned the output yoke by hand and it spun the front yoke as expected. Unfortunately every so often if I’d spin it faster, it would feel as if something inside would slip as if a spline was stripped or something. I put everything back together and with the power divider unlocked, the truck would spin the rear tires even with the brakes at near full pressure, so it leads me to believe it’s okay? Am I missing something? Would the auto power divider make it behave that way when spinning it by hand?

Hey guys! I was hoping someone here had access to part numbers for the chrome mirror covers with lights built in. About 6 years ago I bought a set from an online auction but I can’t seem to find updated part numbers on these so I can get them again for a new truck I’m putting together. I only have what I believe to be the outdated part numbers for the left side: (8413-97429) and (23914107). Can anyone here share the left and right side updated part numbers? What a ballpark price on these nowadays? much appreciated!

Guys, just wanted to post a follow up on this. The truck has been back to work for going on three weeks now. It’s had a 300 mile trip in addition to all the daily on-site hours it has logged, and the oil level still hasn’t risen. I’d call this a fix!! I’d also like to add that we’ve noticed and improvement in fuel economy as well. I’d like to thank you guys, especially Heinz for the help!

Alright guys, I went ahead and installed new cups and injectors. The truck now sounds a little quieter and isn’t quite as strong as before. It’s not slow by any means and I believe it pulls about as strong as our other trucks, but there was a noticeable power decrease right after the injectors. My theory is that maybe the injectors it had on before were off a d13 with larger nozzles? I have no idea, but I’m happy with the results. I will be giving an update in a couple of weeks when the truck works for a bit and let y’all know if this healed the oil level rising problem.

Oh man 😓. You’re a lifesaver! I just went ahead and placed my order on a six pack using the p/n you provided. It ships out today, I’ll get them installed as soon as they arrive and I’ll keep you guys updated on the results after a while of working the truck

Would this cause the truck to be horrendous on fuel economy? We have a mix of 18 speeds and Allison’s. We’ve always known our Allison trucks to be bad on fuel economy but this one seems to be the worst, and this one is also an Allison truck.

Currently the engine has all Volvo injectors with part number 22479123, I figured these were original to the truck? Would the six pack part number you referenced interchange with the ones I currently have? Vin: 1M2AX04C5CM011802

Okay guys, update this morning I’ve exhausted all my UV dye, I’ve never used this much dye trying to find a leak. I’ve checked meticulously around each and every injector, plunger, and both gallery plugs. I still cannot pinpoint a leak. I have a suspicion of a faint uv glow from the injector plunger springs but I’m not sure it’s even that, at this point even the oil pooled up on the head seems to glow 🤣 it’s driving me crazy.. I could be wrong, but I don’t suspect cups just because the engine starts and runs perfectly with no performance issues, no air blowing into the fuel system either.

The truck has about 280k miles and about 20k hours. It’s got the original injectors as far as I can tell

I’ve got a feeling you’re right about that. After inspecting it further tonight I can the the FAINTEST uv dye glow on the injector springs. I will look for new injectors at this point, looks like this is probably my best bet.

It’s for sure fuel, I haven’t got an oil sample yet (going to send some off though) but I’m certain it’s fuel. Put a drop on cardboard and it leaches out. Smells like fuel too.
