HI Anthony.
that's a common mistake people make........they hear 'clutch pedal' and
regardless of which way it is when depressed......quiter than when release
in neutral, or noisy ........they automatically say 'throw out bearing.,'
in a normal world.........a TOB will be noisy when you push in the clutch
pedal.
If you find this opposite scenairo ............................engine
running in neutral, and you push in the clutch pedal it gets quiet, you let
it out, it gets noisy .........
what I usually think of then is transmission input shaft bearings. The
trans input shaft stops turning when you push in the clutch ..........
hence the quiet with the pedal depressed.
there is no adjustment on the hydrualic clutch of a vanagon ..........or
'not normally, ever'. If there's a bit of freeplay at the top of the clutch
pedal travel..........no adjustment is needed, period. They are perfectly
self-adjusting .....very nice design.
people do have trouble bleeding them sometimes.
and there is a spot on the clutch pedal that wears badly ...........the
pivot point for the clutch master cylinder clivis pin .......
up under the dash where you could never see it .........it's a
metal-to-metal thing with no lube really , except what the grease they put
on that point at the factory. You can spray up in there blindly to some
affect.
When this spot wears, the symptom is lots of clutch pedal free play at the
top of the pedal travel. It should be like 1/8th to ........up to half an
inch is ok.....
but syncro's suffer from that.....wearing of that pivot point on the clutch
pedal.
The push rod to the clutch master cylinder is adjustable for length ....
but it's an awful adjustment to have to make. IF they were talking about
that adjustment, that would make sense.
normally though.........the clutch master cylinder push rod length never
needs to be adjusted.
and if the clivis pin pivot point is really worn ........the real repair is
to fix that, not to adjust the push rod length longer to
compensate........though that will work, it's just not a real reapir. It's a
bitch to remove the clutch pedal assembly to repair or replace that part
too, btw.
I wonder if they didn't hang the engine carellessly off the trans input
shaft or something like that, and cause some damage.
A Syncro is a " bizarre, too much stuff jammed in there, hard to work on
thing' ..................to a shop that isn't familiar with working on them.
I hope it gets resolved easily.

Subject: Clutch Noise NOT Depressed
I recently had some work done on my '89 Syncro, and the shop said the clutch
slave cylinder was leaking so they replaced it. Then they did tell me that
they had trouble getting it adjusted.
Now it makes a medium pitched noise when the clutch is released, NOT when
depressed. In other words, when I depress the clutch pedal the noise goes
away.
It didn't make any noise before they worked on the clutch. In yesterday's
posts from another list member, people suggested his problem was throw-out
bearing, but his made the noise when the clutch was depressed. Just the
opposite of mine.
Any ideas?
