69 Z28 clutch pedal requires all my weight and pressure to push down...can this tension be adjusted to make it easier? my mechanic told me it's a 'racing clutch' and can't be adjusted--is he yankin' my chain or can it be adjusted? thanks.

Effort can't be adjusted in a mechanical linkage like a 69 has. The linkage is one solid rod from pedal to Z-bar, which rotates and pushes the lower solid rod against the clutch fork.

About all you can do is make sure the Z-bar is lubed and rotating as freely as it can, and check that your upper rod is in the correct hole in the pedal (lower hole). Other than that, all the effort is in the pressure plate which is part of the cultch package inside the bellhousing.

I guess you could also check that the pedal return spring hasn't been changed or rerouted to make it harder to overcome when you're pushing to engage.

I second Eric's response. Someone may have installed a heavier-duty return spring.

I just did this with mine to get around the header. A little stiffer than the original.

Make sure the throw-out bearing is on the throw-out bearing lever the RIGHT WAY b/c it might not be but yet MAY operate pushing hard on it?????

I'd figure even a stiff PP wouldn't be THAT STIFF!!!

Nope, pedal effort can't be adjusted - your mechanic is probably right; some previous nitwit probably put a 3-finger B&B "race" clutch in it. :clonk:

I had a similar problem. It took a lot of effort to push the clutch pedal down. Turned out the clutch fork I bought wasn't seating on the pivot ball in the bell housing. Defective. Bought a new fork and everything worked perfectly.

I agree with JohnZ. If it's really an effort to drive, you might consider pulling the clutch (probably a 3-fingered pressure plate) and replace it with a diaphram-type unit, which typically requires much less pressure to engage/disengage. The change-over will probably require a new pressure plate, disc and throw-out bearing --$$$, but it sounds like it may be worth it for driveability.
