Hydraulic clutch set up

[SydneyChris]

hi Geoff,

I have been speaking with Mal over the past week, although I had been concerned not to chew up his time with what I hoped at the time were more general knowledge issues.

I only arrived at a position with the dual mass flywheel installed last night to advise Mal the CSS dimensions required. He is machining a lower profile unit to suit the existing gearbox and engine mounts ..

Will post once it back together and functioning.

FFFF Finally.... !!! yes, lots of expletives later, I have a sweet low profile slave cylinder from Mal Wood, complete with a series of conical spacers installed and the drive train fitted back in the car.

I bled the system tonight and checked if the clutch disengaged by turning fitting on the output shaft of the gearbox with the pedal depressed.

After increasing the stroke of the 7/8 MC from 20 to 25mm and using the above method to test it was working, I noted the take up was very early in the pedal travel.

When turning the fitting on the output shaft it was stiff but certainly not requiring more than a moderate amount of effort to turn. By contrast, with the gearbox in neutral, the effort required to turn the fitting on the gearbox output shaft would be considered as 'light'.

Its very much a newbie question, but is the observed level of resistant to rotation of the fitting on the output shaft considered 'normal' when in gear with the clutch pedal depressed... which would then confirm the clutch is fully disengaging..???

With thanks

Hi Chris,

It does take a little more effort to turn the output shaft depending what gear you are in, the clutch may also still be "dragging" since the plate is new.

For example in 4th gear, the input will spin at the same speed as the output shaft while you turn it.
In 1st gear, the input shaft will spin about 3 times output shaft speed.
So in a lower gear it will take more effort to turn the output shaft.

But if you can turn it by hand (clutch pedal depressed), and can't turn it (clutch pedal released), then you must be ready for a test drive.
