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 I only have what I believe to be the outdated part numbers for the left side: (8413-97429) and (23914107).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.

No other concerns besides the rising oil unfortunately 😞. Truck starts and runs great. No misfires or smoke. I’d hate to throw parts at it and I don’t have much time to work on it before it has to go back into service in a week and a half. If I can’t find anything else tomorrow then I may just have to put it back together and order a set of injectors to throw at it next time it come back to the shop and hope it fixes it. Meanwhile we’re changing the oil once a month

Do you mean the fuel pump that mounts behind the power steering pump? I thought about that but fuel isn’t mixing with the power steering fluid, which I assumed was the first thing that would happen if the fuel pump seal went out.

hey guys looking for some help on this one. I’ve got a 12’ Mack granite with an mp7 that’s making oil. Oil level rises about a gallon every two weeks. I’ve put UV dye in the filter and checked to see if I could find the leak, I found nothing around the injectors or galley plugs. I then added another ounce of dye directly into the fuel gallery through one of the plugs and still nothing. I can’t find the leak even after hours of looking. Anyone have any ideas on where else these engines can pass fuel into the crankcase?

My understanding is that anything 44k and over has the transverse rod. Just based on what little I’ve gathered, it seems that the only difference between a 44k and a 46k is that the 46k will have cast iron axle housings, whereas the 44k has stamped steel housings. I’d like to be able to know for sure though.

As the title reads, I’ve been around Macks from the 90’s up. One thing I’ve never really understood are the differences between 44k and 46k camelback suspensions. Does anyone know what it would take to upgrade a 44k to 46k? A local guy has what he claims to be a 46k cutoff but it appears to have the same leaf count and size as my current 44k setup.
