heraldhabitat Posted October 31, 2010 Share Posted October 31, 2010 Have you used the whole of the 1500 clutch, eg flywheel, pressure plate, drive plate and thrust bearing or the whole 13/60 set up? You can't mix and match (I found out the hard way!!)I do think this is posted in the wrong area it would be better in the herald section....

Clive Posted October 31, 2010 Share Posted October 31, 2010 I reckon technical! So I have put it here :)Hmm, is the slave cylinder set up so the bleed nipple is above the feed pipe?Does th eclych arm move immediately the pedal is pressed?Is it the correct slave cylinder (groove down one side, not all the way round)What brand of clutch was fittedBTW this is a discussion forum, so people will put replies on the board ;) Link to comment Share on other sites More sharing options...
PAULK152 Posted November 1, 2010 Author Share Posted November 1, 2010 thanks for the reply and no the bleed nipple is on the bottom - as set by the mechanic I called in - so this can be changedotherwise everyt thuing is as you suggestedsomeone has suggested to me that nair can often be a problem and reccommended connecting the brake master cylinder direct to the slave cyl nipple and using the brake pedal to pump fluid through the clutch system in reverse to expell all the air - ever done it like that..?Paul K 152 Link to comment Share on other sites More sharing options...
PAULK152 Posted November 1, 2010 Author Share Posted November 1, 2010 to Chris Allen WMOYes I have mixed and got spit 1500 flywheel and complete (new) 7.5" clutch mated to a 13/60 set up including bell housing and (new) release bearing + existiing arm.what did you find - when you did this as I have a spare spit 1500 gear box and bell housing complete ( in poor condition) but the "1500" the release bearing arm only moves a fraction of the distance moved by the currently fittedt 13/60 set up ....... I thought it should move at least 3/4 of an inch..?? would appreciate your adviceregardsPaul K Link to comment Share on other sites More sharing options...
