Adjusting the clutch

[gwynthompson]

Hello All. i have fitted a new clutch and release bearing. to my 1979 4. i have looked at the haines book. re adjusting clutch. peer into the slot on top of bell housing. with a torch.
there should be 3 or 4 mm between bearing face and pressure plate. i cannot even see the release bearing.!!!!!!!, i can see parts of it. i got my wife to gently press the pedal down. i adjusted the cable untill it looked like a small movement of the bearing untill it pressed on the pressure plate. but not having xray vision i am not sure its right. seems very err ham fisted. is there a cunning more accurate way. to get it correct. i still have a crunchy second gear. i could not find a new sychro hub anywhere. so could only clean up the old one. and hoped a new clutch might improove it. but is about the same.!!!!!. after a whole winter of dismantleing.

Hi. Don’t know what Gearbox you have, but from a dim and distant memory on all of my Mk 1 R5s, there needs to be a small amount of play on the cable and fork operating lever. There is a measurement some where it may also be in my R4 manual, I’ll have a look, it’s literally only mm’s. In other words just by touching the clutch pedal won’t induce slip and the pressure plate is fully seated.
Also I think the output shaft splines should be given a small amount of grease.
I ll dig my R4 Manual out.
Ian.

Welcome to the forum. There needs to be about 3mm of play of the cable at the fork end, 1/8th of an inch in old money, so the release bearing just clears the pressure plate.
