Hydraulic throwout bearing type 1 IRS box

[Pablo]

OK I've been in the garage retrieving the sleeve from an old box..

By my great powers of measurement I get the PCD of the mount holes to 54mm & the holes are equidistant

Diameter of the input shaft is 20mm at the widest

Length of the sleeve is 60mm

I have a car under wraps (from the weather) with the engine out but the bearing still on, so I could get someone to press the pedal & I can measure the travel of the bearing.
I just have to get the time to unwrap it. cant do so until next week.

An adaptor looks the way to go and easy enough to get made

Thinking economies of scale?

The measurement might give some good indications of what needs to be done in terms of depth and throw BUT how do we measure how much is actuation of the clutch, presumably if we can get the full movement range then it'll be good?

If you do get a chance, measure the bearing too for diameter.
