If you read my last post - 'Hydraulic clutch slave' which was about fitting a hydraulic clutch to a Porsche 915 gearbox you might have thought that it was a good solution to an otherwise difficult issue to solve. Well that is what I thought until I tried to fit everything together. What I actually found was that the slave cylinder that I used was too long and meant that it fouled on the clutch assembly when the engine was installed in the gearbox. With limited time to buy and fit another shorter unit I decided to look at converting the old pull style 915 clutch release to a traditional push style.
