Clutch testing?
alfasudsprint - 27/9/04 at 08:48 PM

Any ideas on how to test if the clutch is diengaging correctly without the engine running?
Am playing around with mine (oo-er!) its hydraulic, should I be able to push the release arm easily with my fingers?...that is without the return spring attached!
Am pretty sure the cylinders are not working well as the pedal does not reurn, and when pulled manually the lower cylinder does not return either, completely...any ideas to free them up...tried WD40...need to dissassemble and grease?

thanks
Tim

what you have there is a foot operated hydraulic pump and a single acting linear actuator. This means the oil flows under pressure one way only, its the spring that makes it return. so if moving the pedal causes the cylinder to extend there is nothing wrong with it, but if its spongy it may require bleeding. Do not grease the cylinder, it will probably attack the seals.

when cylinders leak they are normally past their sell by date and ready for the bin,wd or grease is sure to kill the seals

Thanks guys...no leaks thank God, so need to look at the 2 return springs then.
Does everyone test their clutch when the engine's running? Any other ideas?
