Clutch sticking

[saskboy]

I installed a 5.0 and 5 spd into 1996 ranger, flywheel, pressure plate and disc are new, trans from 1989? f150, slave is what came on trans. Pedal effort seems normal, very little play at top, travel all the way to floor seems normal. I see this a common swap, does ranger master always work with f150 slave? Problem is can't shift with engine running, if started in gear truck wants to drive away. Where's the problem?

Yes, Ranger master will work with F150 slave
Bore size is the same 7/8" or 0.88 for either master

Couple of things
Did you use a new clutch disc and pressure plate?
If not a new pressure plate then that could be the problem, may have an old SAC plate that needed to be reset

Feel the hose going down to slave from master when someone pumps the clutch pedal
These hoses can wear out and expand in spots so you lose full fluid flow to slave

Because the Ranger master sits at an angle up, air can get trapped at the top and won't bleed out with normal bleeding
You need to pull out the master and point it down then pump it to force any air out of "the top"
There is also a C-clip at top of master that can be removed allowing piston and air out

Look in the reservoir while someone pumps the pedal, you should see no flow up into reservoir, if you see that then master is bad, well check valve in master is bad

Feel at the top of the pedal, its pivot point, the bushing there can wear out and pedal can shift a bit so you don't get full pedal travel
