Between the greedy oil companies and the brain dead Biden administration there bound to bankrupt this country 

Thanks, I didn't know one was already started. 

Ok,Thanks, I must have missed it. I Didn't know where to post it either.

Doug Fetterly called me earlier this week and had some sad news that Mike Harbison Sr. has passed. He was a good friend and will be missed dearly especially by the Mack Truck family. Everyone keep his family in your prayers. Seems like we're loosing too many friends every year. Everyone be safe over the weekend.

Coker Tire

Bypass the air dryer to see if it builds air. I have had 2 of them plug up, I put a fitting in between the inlet and outlet to get by until I can get a cartridge. 

Nice job on the conversation, what size is your Rat motor 

What's the difference between 690 and 690b.

The older engines had studs can't remember when they started using bolts, I have seen broken studs I had one on my 315. Went to bolts hadn't had a problem. 

I don't know if you can get after market gaskets or not, but you might have to resort to used parts to fix it. What kind of parts are you looking for. 

The hub that the harmonic balancer bolts to 

Water pump and water pump housing..

Is there certain years on the e7 that the expansion plugs in the rocker shaft that can fall out an lose oil pressure. Thought I have read something about this.

Take it to a diesel, injection shop and get it rebuilt, I had one rebuilt the cost was around 200, 220 dollars 

The diesel and injection place I had my pump rebuilt. rebuilt my suppy pump too, don't know why it can't be rebuilt unless he has the tachometer drive supply pump.  Did Mack quit using the tach drive pump on the e6 4 valve. 

If you take the cover off the fuel pump you can soak it down with some PB blaster, you might pull the intake tube off and have a big rag you can block the airflow just in case it runs away. Good luck 

If it's been sitting a long time probably the rack stuck in the pump 

Peanuts in the Power divider wore out???

Going to Walcott I got 11mpg  B61, 300+, 13 speed Overdrive roadranger, 3,87 rears, twin scew. Put a trailer on it and drops down considerably.     

If I remember he posted a while back something about he was building air and the air built up and the selector valve was in gear and messed something up in the transmission. Must not had it in neutral 

I guess I should have made myself more clear, I should have said front axle. Sorry about that. 

We ended buying a new one, you can send me a picture if you want to. They must have made a few different styles. 765 202-4025. 

Thanks Ron. 

What's the number on the axle
