Hi Neil,
I have a pedal assembly out of a syncro that I removed for worn clevis pin
hole..
'one of these days' I hope to rebuild/repair that extra heavy duty like..
maybe bronze bushing for the hole.
Bronze is self-lubricating I believe, and if that pin is only say 1/4 inch
diameter..
there maybe be room for a 5/16th inch diameter pin say.
should have a grease fitting somehow, even.
back in the 20's or 30's, there were even a few cars with a central grease
reservoir, and a foot pump or something would grease about 50 or more points
on the car. Think I read that somewhere.
Wish VW had gone to more effort on that clutch pedal clevis and pin pivot
point...it's kinda the weakest built important mechanical mechanism in the
whole van.
The clutch and brake pedal main pivots, at the top of the pedals, for
example, are just bomber and never wear at all that I've seen.
have fun fixin' 'er really well.
and lubrication ...
anything that moves on anything, with a few exceptions needs some
lubrication now and then.
I even lube the ash tray cover pivot points sometimes,
I lube where the wiper arms pivot on the part that's on the wiper shaft ..if
it moves ....
in the military they used to say something like 'if it has brass on it,
salute it, if it doesn't , paint it. " ..
something like that - so ...if it moves, lubricate it.
I'm tempted to start a data base of points I lube on vanagons, maybe
publish parts of it on Fridays'.
It's hundreds of items long.
Drives me nuts to see a vanagon with a grand's worth of fancy wheels and
tires on it , yet the rear hatch strut pivot points on the body are rusted
to nothing, and struts falling off, due to lack of even a bit of bailing
wire to replace the missing e-clip and a shot or spray grease once every
year or so ...
so little effort to make such a big improvement ....just lube things that
move.
and really, if a person actually lubed every single thing on a vanagon that
can use lubrication ..
and actually serviced the whole van throughout properly............every
part on it would last almost indefinitely.
Or close to that.
anyway, maybe yours is just wear due to ..
you know, 'little dab'll do ya.'
Scott

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.
