clutch gap

[timcasbolt]

How much gap should there be between the clutch disc and flywheel on a small block chevy and Muncie 4 speed when the pedal is fully depressed?

depends on how ya set it up . free travel etc. Longs as it spins and releases all the way you are ok .

Ok. Thanks. Not my area of expertise. Helping out a friend. Right now it creeps with the pedal all the way to the floor. Not sure how far to adjust the rod. I'll try turning the fitting about 5 turns and take it for a spin. Sound about right?

I like to see 1 inch of free travel in the pedal from rest to when you push down on it and you feel it just touch the pressure plate

Reverse is not synchronized.

If it grinds when engaging reverse with the clutck fully depressed long enough for the countershaft to stop spinning due to friction, the clutch is out of adjustment or other problems exist.

If everything else is right, 1" of free pedal travel is about right.

timcasbolt --

The flywheel surface, clutch disc, and pressure plate surface should be flat AND perpendicular to the engine's rotational axis.

If they"re not, it's possible for the clutch to fully disengage at one rotational position of the transmission input shaft relative to the flywheel and pressure plate, but only partially disengage at some other rotational position.
