My clutch has been making noise for some time now when the pedal is depressed.
I figure the throw out bearing is going bad. Outside of the noise the clutch is
working fine. Its been doing this for about 2 months so I went ahead and got
most all the parts I think I'll need. I've noticed fresh oil in the driveway(a
novel thought) where I crank up and put the clutch in every morning. Over the
past week the sqeaking sound turned to screaching sound. Then it happened, you
crank it up one morning and the car won't go into gear with all the screaching
as before. I figured this might be due to one of two things:
1.Clutch drive plate has oil on it from a bad rear main seal or bad tranny seal.
2.The bad throw out bearing(TOB) has caused enough wear on the fork pins to
loose enough effective movement.
Question: Can a bad TOB cause the car not to go into gear? Could the bearings
be so far gone as to collapse enough to create effective lost movement of the
fork?
I checked the movement at the pinned connection of the slave pushrod to the
pivot bar of the fork. There are three holes there and mine was pinned to the
innermost(radially) hole. It appeared to be at an awkward position(cocked) and
the outermost looked better for making the pushrod more linear to the slave
cylinder.
Question:Does anyone know which hole is correct?
The linear movement of the slave cylinder pushrod 'looked good enough' at about
1.25~1.5 inches upon pushing in the clutch pedal.
Question:Does anyone know what 'good movement' is as I rebuilt the clutch
master and slave cylinders resulting in no change in that movement?
At this point I'm about to dive into the clutch as I know/assume I have to
replace the throw out bearing(TOB) anyway. I plan to replace the pressure
plate, friction disk, TOB, sleeve, 2 fork pins , 2 fork pivot bar bushings and
fork lock screw. On the engine I plan to replace the rear main seal and both
seals on the tranny.
Question:Does anyone have any suggestions or pointers on things to look out
for(besides the car slipping off the jackstand ;-)?
All info. will be greatly appretiated!
