Hello all,
86' K20 SM465. I replaced clutch, pressure plate, etc. I've got a little chirp when my foot is completely off the clutch pedal. If I put even a toe on the pedal the chirp stops. This makes me think the system needs a half mm adjustment. There's no adjustment built into the pedal assembly or with the slave cylinder(that I can see). The only thing I can see that might be adjusted is the pivot point for the clutch fork. It appears to have a place for an allen wrench, but is all but inaccessible. Any tricks on how to get this thing adjusted back a skosh?

The ball stud isn't an adjustment point. With the hydraulic clutch there should be no perceptible play. Now I do think there is a little adjustment at the pedal but that's it. Should be you get the system bled and that's it. How old is the whole clutch system(clutch pressure plate, fork etc)

Sorry Tapatalk won't let me edit?? But just reread and saw you replaced everything, did you add a little grease to the splines and throwout bearing surface? And the pilot bearing?

I tried to get some WD40 in there with the little red extension, but I couldn't get it to find the sweet spot. The hole where the clutch fork goes in is little and at a bad angle to visualize where the throw-out bearing and the pressure plate splines meet. There is a grease fitting close to the clutch fork access, but I can't imagine grease reaching all the way to the where I need it. I can give it a try though.

When you throw everything together your supposed to dab a little grease on all contact points- not too much though as you don't want it to get on the clutch plate itself, and that grease fitting is just for the ball stud, it takes a lot of wear, so about every other oil change you should do a half to a full pump to get fresh grease up there.

I need to get one of those dentist mirrors on a stick so I can see in the clutch fork opening and spritz a little lube in there. Without getting any on the clutch plate of course. Thanks for the correspondence, I'll try to let you know what I come up with

Just as an update.. On another random forum I found some other guys having my same problem. They suggested white lithium grease using the red extension to get in there. To my amazement I found the sweet spot and was able to get the chirp to stop. I drove for maybe fifty miles over two days and started noticing it come back just barely audible, so I imagine I'll have to do it every so often(hopefully not every 50-75 miles, but at least I know it's an easy fix. Thanks again for the dialog!
