Hey Scott.
When I installed the new clutch MC, due to newb ignorance, I never
adjusted the cylinder push rod. It worked fine so....
And grease at pushrod end where it meets MC piston? Had wondered today
if I should have done that at time of install. For sure! Great idea.
If I pull the cluster out, I'll do that. And of course lube the clevis
etc. It was a while back, but IIRC, I hadn't lubed anything beyond the
bushings at time of assembly. Bad move. D-oh!
The click sure feels like something that "settles in" to place once
enough pressure is exerted on it. Yah. I bet the clevis hole repair I
did failed OR the clevis pin is worn and settling into place. Can't
feel anything rubbing up there.
Now that I have a MIG, I bet I can do a better job of it. ... or just
replace the pedal with the good one from the '85 (thanks again for
prompting me to pull as many parts as possible off of that parts van a
coupled years ago). That pedal cluster looks nice.
I had read of the access hole in the archives. Seems maybe overkill
somehow, but makes sense. Such a PITA thing to get to.
Neil.
