Subject: "Wish in one hand, _____ in the other..." Clutch ?
Content-Type: text/plain; charset=ISO-8859-1
I've recently had my engine out. Inline 4 VW/5sp manual tranny. It
went back in with significantly more power (result of a new block). I
re-used the clutch and flywheel from my 1.8liter block, un-touched, on the
"new" 2.0liter block. I did not replace anything. Everything looked to be
in acceptable shape, so I bolted it all up. Now my clutch is slipping under
load. I have searched everything online on Clutch slipping..and it looks
like I have a 'clutch job' to do, but grasping at straws here, I am
wondering about cheap/easy fixes, first. That quote in the subject line
goes: "Wish in one hand, crap in the other hand and see which one fills up
first" and is an old Ski Patrol saying from my Jackson Hole days, cleaned up
for a family list.
It's mentioned in Ben's Pages that adjustment might be a cause of
slippage..Is that just the pedal freeplay adjustment? I wanna check the
easy stuff before I remove the tranny for a real look. The clutch pedal
does feel pretty "close to the top"..Would changing the block affect the
clutch pedal/linkage adjustment? Could I possible gain some more grip with
a few turns on some rod somewhere?....
Could the parts be 'not fitting' correctly? Like the flywheel / crank
being different, given this is a different crank bolted to the old
flywheel? Would that cause the clutch to be "too loose"? When I snugged up
the pressure plate, it had about 4-5 millimeters of space when the
bolts came finger tight..Was that too little, causing the pressure plate
(clutch basket?) to allow slippage? The 'new' motor does exert a
significant amount more power. The clutch slipped as I was climbing a 6%
hill in my 4th gear and lugged the motor at full throttle to see how the
timing might be....She just spun up under power without touching the clutch
pedal..
I have oil dripping. I know now that I should have replaced the pilot
bearing and all those nearby seals (which looked good, but..) I get a spot
of about 6" diameter when I park after a highway run...coming from the
junction of tranny and engine. I will be raising the rig back up today to
have a look...I could easily have a leaking pan (diesel-style, engine sits
in there at 50degree slant) causing that drip...The rear main seal of the
2.0 liter block showed no leaking, so I didn't replace that, either..My
tranny was not leaking into the T.O. bearing area, either.
any advice?
thanks, Don Hanson
