You might also remove the flywheel inspection cover and take a look at the pressure plate (does this truck have a Dual Mass or Single Mass flywheel?). Cheers!
The clutch pedal stays all the way on the floor with only about 1/2" of total pedal movement. If I pull up hard on the pedal, it just pulls the push rod out of the master cylinder. So I haven't been able to get the slave to move at all with the pedal.
There only seems to be very minimal movement in the pedal box bushings during pedal movement, but since I can't move the pedal while everything is is hooked up, there is no pressure to push against except what is provided by the spring.
I picked up a new fork and with a side by side comparison, I can't see that the old one was bent or more than slightly worn. But I installed the new fork just in case.
The truck has a single mass flywheel.
I have removed the flywheel cover and looked up through the clutch fork hole and don't see anything amiss but since this is all new to me, I'm not sure what I'm supposed to see.
As far as I can tell, the fork is reinstalled correctly. With the retainer clip on the slave push rod, I still have to push the rod in a bit to get the slave cylinder installed.
I sure appreciate you all helping me out.
