m8540 shuttle shift problem??

[jthurst]

I have a m8540 that acts like a brake is grabbing, it will stop itself with clutch pushed in going down a hill and has a hard time taking off in road gear. We jacked rear end of tractor up and both tires turn hard with tractor off and out of gear. Local shop suggested taking brake line loose and turning rear wheels when off ground, didn't make a difference. Local shop is now saying it possibly has shuttle shift going out. Anyone have experience with anything like this?

Welcome to OTT
I think hyd brakes could be the problem from possible disk dragging. Which type shuttle(hyd or synchro)? If hyd shuttle it might be possible control valve is allowing pressure to both fwd & rev clutches.

It is a hydraulic shuttle shift.

If I remember correctly the tires aren’t “Easy” to turn on my 9540. I know that if the Hydraulic valve for the shuttle shift isn’t adjusted right it will do some crazy thing.

I don't know if this will help you - Hydraulic Shuttle shift lever adjustment.
