It's about between 1/4 to 1/8 far . I can't found the problem I checked if the bracket has space between the head and the bracket the answer from cat was no . I checked the dumper and the poly for anything that can cause the problem . Everything ok . The only thing I'm thinking that it is spacer between bracket and cylinder or head . Or bad design by cat . Or crankshaft problem
Customer reply replied 9 months ago
Or may be crankshaft moving forward

The crankshaft thrust washers are in the same location when the rod and mains were installed I am assuming and the end play is in specs? Is the crank out further than it should be towards the radiator or in to far towards the engine?

Was any work done to the crank or was this an inframe?

Inframe only

Thrust washers the same and in the same location on the crank? end play tests in specs? That is what I would verify.

I will check the spec . They don't need to put washers between poly brackets to engine block to move all the Pollys forward?
Technician: Daniel Wilson,

Are there washers there now? So to clarify, the crank is out 1/8 to 1/4 towards the radiator and the pulleys are too close to the block by 1/8-1/4 inch. This ia a serpentine setup or v belt?

Gotta run to an appt for 2... those are the instructions for the install for the Pulleys.

The support bracket going direct on the engine or they have any washer/ spacer between the bracket and the engine

It is not showing any washers. By chance did you notice any problems with alignment before the rebuild? How does the belt look? Wear on one edge?

Eaton trans issue. 2002 peterbilt 379 eaton 18 speed rtlo
Truck hesitant sometimes to do range changes from high to low. Not the small plitter button. talking about the bigger paddle. Truck does not grind at all when its having issues. Sounds like its the range piston having issues. IF it does not complete the range change while in neutral, it will change the range the instant you touch a gear with the shifter. you can do this with the engine off as well. I was thinking to change out the range piston seals but the manual says you cant do this without removing auzilary section on this model trans for whatever reason. Local transmission shop told me its the synchros going out. I find this hard to believe because I get no grinding during range changes. … read more
