Clutch slipping when hot and climbing under load

So the clutch is new? Need to make sure the hydraulics are working like mentioned. I wonder if they never removed and resurfaced the flywheel, or got it all dirty during assembly. If it was recently replaced, find out who did it and try to take it back and see if they can do anything for you. If you are stuck with it, before you replace it, there is a burn in procedure you can try. Not everyone agrees with this, but we have done this many times with great success. Get it so it starts to slip and then increase the rpm to keep it slipping for a good 20 seconds, then let off. This will burn off any impurities and burnish the mating surfaces.

 

Hope you get that fixed. I am wondering, mayby Im behind the times, but why are manufacturers putting in hydraulic clutches? Just so they push easier? If so why don't they just refigure the linkage better. My 2001 pete pushes so easy. With the easy pedal eaton clutch.

 

When the hose going to the slave cylinder fails, it usually fails internally and turns into a check valve. Which means that you can pump fluid through it when you depress the clutch, but when you let off the clutch, the hose will not let the fluid flow back out of the slave cylinder. Change the hydraulic hose.

 

Less maintenance, easier to repair.

 

Hydraulics are nicer to push. On Internationals, there is an air assisted option as well and pushing is really effortless. I agree, this is just another way to unnecessarily over complicate trucks when other tried and true methods have worked great for many years. Engineers need to justify their existence you know, LOL!
