Clutch slips when hot
Posted: 10 Feb 2018, 19:14
Hi All
Tried the usual googling but can't find the answer to this one so hoping someone can help.
Some background:
Clutch slips slightly when hot (usually when the turbo kicks in in 3rd-5th). It's had a new kit approx 600 miles ago when I had a second hand box put in, problem first appeared after a few hundred miles at high speed on the motorway but I can get it to do it after 10 mins at 60mph now.
My expectation was it was likely to either be adjustment of the hydraulics or contaminated clutch, hoping the former. I've never dropped a gearbox before but decided to have a crack at it as my local garriage seemed reluctant and I'm not too keen on paying piles of money on labour for a non working drivetrain and I wanted to rule out gearbox leakage. I got as far as removing the slave cylinder before I noticed an inspection hole in the bell housing, why had I not noticed that before! Decided to re-assemble, get it hot again and shove some clutch cleaner down there to see if that made any difference before going to the trouble of dismantling anything.
Now, to my question. On re-installing the slave cylinder, I noticed that the rod is protruding further than the start of the clutch lever swing. I could get it on by tightening the bolts but that will deffo disengage the clutch a little leaving me with negative free play which leads me to think that this may have been my problem all along? I'm thinking if I bolt the slave cylinder back down then open the filler cap under the dash, the fluid should rise as the diaphragm spring returns the lever back to it's natural position and with any luck I should be sorted. Does that sound right or have I missed something here?
Cheers
Laurence
