intermittent clutch slip ?

[John Eyles]

So does nobody have any suggestions as to what
would cause an intermittent clutch-slipping problem
in a clutch that's less than a year old in a 97
Legacy OB 5-speed ?

It SEEMS like it develops when the car has been driven
awhile and goes away if it's parked a couple hours.
The difference is pretty dramatic.

Thanks, John

Could be that the clutch is not fully engaging. First check the free play
and adjust if possible and then bleed the clutch cylinder and lines. eddie

Note of warning, I'm pretty clueless, but thought I'd add something:

Do you have the standard amount of pedal play? (as described in the manual)
My 95 has a cable (yours is probably hydrolic) and I know every so often the
cable need adjusting otherwise as the clutch slowly wears, it won't engage
with enough force. You can tell because the pedal loses the 1" play.
Maybe you don't need to do this with hydrolic clutch, but maybe there are
other things that can break

Anyhow, sounds consistent - clutch always slips a little, causing it to heat
up and when it is hot, it will slip worse (like brake fade); it cools down
and it will slip less.

I have had clutch problems with my recently purchased 99 Outback....engaging and disengaging low, sticking. Only happening in heavy usage. Ok after it has sat for a while. Had the fluid drained and replaced. Same problem still occured. I have now been advised that the problem is the clutch slave cylinder which is now being replaced. Hopefully this will fix the problem.

They didnt turn you clutch disk, it wore down your clutch. You need a new
clutch. The reason it shudders is because they didnt turn the clutch disk.
The reason its better when you havent driven it a while is because its still
cool... once it warms up it starts to slip. Go to a reputable shop and have
your work done there.

You don't turn a clutch disc (or pressure plate) - you throw them away and
put in new parts. If you're thinking of the flywheel, then that can be
turned if it shows severe galling or grooves. Sometimes it makes sense to
put on a new flywheel.

I dont know why I was saying clutch disk. Flywheel it is. It needed
turning. It has grooves and warps in it. He gave the exact and perfect
description of it needing to be done. Down to a T.

OP here ... took my car into Subaru dealer who did the
clutch replacement last year and they just called and said
the adjustment was too tight. They adjusted it and claim
all three problems (judder, slipping, tight pedal) are now
gone. I'll believe it when I test drive it later today.

Thanks for all the advice, John
