Hi Don,
the smart thing is to get a Sachs clutch kit ..
you get pressure plate, disc, and throwout bearing.
I've just excellent luck with those.
they happen to be 'rebuilt in mexico'....
but they just fine ...sachs original german parts ...
then they do whatever they do to them. ...but a most excellent clutch kit,
have used them many, many times in diesel and vanagon waterboxers.
the kit is less than the indivudal parts of course.
you could/should have a new diesel vanagon pilot bearing on hand, if you
find it needs one of those.
Those pilot bearings ( *like all the metal parts that come into contact with
each other throughout the entire van are just fine ..IF ..they get proper
lube .....I'm seeing that over and over ....the parts would not wear, if
they just had adequate and fresh greases and oils ) ..
anyway ..
I try not to sufrace flywheels. If it's all blue and checked and there are
tiny almost cracks, then I supposse you have to , but normally, I clean up
the surface with 180 grit black waterproof sandpaper and carb cleaner ...
a few minutes of that ....they're usually fine.
- you know me ...'It's not in the parts...............it's in the
Workmanship' ..
getting the flywheel really prepped nicely is a good example .
oh, the discs last exceptionally well. I have pulled on out of a 4 speed
diesel vanagon that had no 1st gear for about 1 1/2 years ..and the disc was
just fine.
chattering from oil contamination ....
better to put in a new one. I've even seen someone burn the oil out of the
friction material on a clutch disc with a propane torch, though I don't
recommend that !
RMS ...rear main seal..
get one that is black with red lip, or all red ..
the plane black ones don't last that long.
for detail workmanship clutches are one of my favorite areas.....when I work
on just the part inside the bell housing ..I do like 20 seperate little
things ...
and I pay particular attention to where any metal moves or slides or engages
with any other piece of metal.
extra.... about lube and metal -
I see dozens of vanagons a year.....and work on them from one end to the
other ..
I constantly see CV joints without engough grease in them. Nearly every
last one ....some almost very dry ....my point is, they will not even wear
at all, almost, if there is good grease near and in the parts that move.
the only 3 lubes I can think of between the tops of the pistons ( where the
driving force that eventually gets to the rear wheels starts ) ..........is
engine oil on crankshaft bearings etc...
then that is transferred to the transaxle ( and I find lots of those with
gear oil in them that's just kind of old....has very fine metal particles in
it ...that copperly look ....5 years is a LONG time on any gear oil in my
opinion ) .
............and then from transaxle to CV joints ..
those balls pushing on what they push on ...all that needs decent and
somewhat fresh lube on it .
And no kidding ..
engines wear, yes ...and if you changed the oil every 2K miles ( a very,
very general interval ) the engine would wear much more slowly that usual..
but all the rest of it ....If Kept Well Lubed with fresh lube ...
would barely wear at all. I'm sure a CV joint will go 250,000 miles if
driven nicley in a not too horrible envirmoment, with a good rubber boot and
good grease in there. The grease seems to very slowly dissapper ..and I
do not find that the stock amount of grease is adequate after a while, I put
in some extra.
my point is ....fresh and generous amounts of the right lube on every part
that moves ..
and a vanagon would barely wear out at all in many areas.
anyway...just sad for me to see these old beauties not being taken care of ,
when the tiniest shot of lube will keep shift linkage, door latches etc etc.
working just fine forever. And nice black slimey moly graph grease in
there with the CV joint balls.....kinda of a turn on even.
'Fixing a vanagon when it breaks is a horrible way to take care of it."
