reb78 Posted November 15, 2009 Share Posted November 15, 2009 Dont think you can adjust the slave cylinder pushrod, just the pushrod on the pedal. Did you fit the slave cylinder the correct way up? If the bleed nipple is lower than the input pipe it is upside down and you will have trouble bleeding it properly no matter how long you bleed.

western Posted November 15, 2009 Share Posted November 15, 2009 There is no adjustment for the slave cylinder rod, I think Errol got himself confused while writing his reply. slave cylinder should have it's bleed screw at the top or as close to the top as the attachment bolts will allow. reckon there's still air in the system.

PaulMc Posted November 15, 2009 Share Posted November 15, 2009 If the pedal is sinking to the floor and you aren't losing fluid, then the Master Cylinder seals aren't holding pressure. What make is your new Master Cylinder - LR Genuine Parts, Delphi/Lockheed, or the dreaded Britpart? Britpart ones have been known to be $h!te, straight from the box You can test the Master Cylinder by clamping-off the flexible hose USING THE CORRECT TOOL and the pedal should be rock hard and not sink. .

Briarston Posted November 15, 2009 Share Posted November 15, 2009 hi 200tdi disco engine in landy 90 fitted new complete HD clutch, release bearing, welded the fork fitted new master cylinder fitted new slave cylinder (TD model) i can drive but after a while the cluch pedal goes almost to the floor pump the pedal and i seem to get the clutch back after a while the pedal goes to the floor?????? when i engage 1st gear i only have to release the clutch a few inches and clutch bites what else can i do check????? i have bled and bled the bloody clutch until i am blue in the face many thanks Have you moved the pipe to the slave cylinder over, so that its as far away from the exhaust as possible? You could try fitting a heat shield between it and the exhaust. With the Disco engine fitted, it's very close to what is about the hottest part of the exhaust, which can cause vaporisation of the clutch fluid. Some recommend using high temp. brake fluid. Hope this may be of help to you!(at least, something else you can check) Quote Link to comment Share on other sites More sharing options...

big ives Posted November 18, 2009 Author Share Posted November 18, 2009 hi all just a little up date on the clutch problem started at the begining and carried out fault finding, checked the master cylinder by putting mole grips on the hose, hard pedal checked all the pipe work, as stated in another post CV on LR4X4 found the hose to the slave cylinder badly twisted, removed the slave cylinder and fixed. used westerns drawing and set the master cylinder exactly as per the drawing (to be honest it was close to the settings) put every thing back together and bled the clutch and GUESS what its working IN FACT "GREENGRASS" PAST THE MOT TONIGHT yesssssssssssssssssssssssssssssssssssssssssss the 90 also had insa turbos on and nothing was said about them to be honest i cant see what if anything i did different but i now have a working clutch many thanks to everyone who posted big ives aka Ivan Quote Link to comment Share on other sites More sharing options...
