1G Clutch master adjustment solution

[rdeis]

Hey all, wanted to post my answer to the clutch master cylinder adjustment problem.

I’ve found that I cannot adjust the master cylinder pushrod enough to get the clutch to fully disengage. It’s especially bad with aftermarket master cylinders and aftermarket clutches, but I’ve even had the problem with OEM parts.

My problem is that either the rod is too short or the clevis doesn’t have enough thread, so I can’t back the rod out far enough.

My solution is to extend the thread:

Now I can screw the master cylinder pushrod into this extended nut and back it out as far as I need to complete the adjustment.

The coupler is an 8MM x 1.25 metric coupling nut. I use a set screw the same thread size to screw the clevis to the coupler. If you prefer, you can weld the coupler to the clevis, that works, too.

I’ve used this method with success on three cars now, all using different clutches and (probably ) different hydraulics.
