shadowbane Posted July 9, 2011 Share Posted July 9, 2011 Ok so first lets make sure i have this right, the slave cylinder is the little pump (for want of a better word) under the tunnel that presses when the peddle is pressed yes?if that's the case...When removing this should it not be full/awash with clutch fluid? or should the recess where the little arm is be dry?

firebobby Posted July 9, 2011 Share Posted July 9, 2011 Yes it's the alloy cylinder by the gearbox and yes it should have some fluid in it to push the piston inside when the pedal is pressed. :) Link to comment Share on other sites More sharing options...

firebobby Posted July 9, 2011 Share Posted July 9, 2011 Pin? :-/ on one end of the cylinder you have a bleed nipple and the fitting for the pipe and on the other, there's a rubber grommet which the metal bar/rod goes through, this rod sits inside the slave cylinder one end and the other end is pushed against the clutch fork.The inside of the cylinder should be dry and quite shiny.John Link to comment Share on other sites More sharing options...
shadowbane Posted July 9, 2011 Author Share Posted July 9, 2011 yeah pin/rod THAT part...where the cylinder sits into....should that be bone dry, greased or full of clutch fluid? :) Link to comment Share on other sites More sharing options...
firebobby Posted July 9, 2011 Share Posted July 9, 2011 If you think yours has a leak, check your fluid levels.I don't know if they are bone dry but they shouldn't be wet, as in visable fluid weeping Link to comment Share on other sites More sharing options...
shadowbane Posted July 9, 2011 Author Share Posted July 9, 2011 I'm just getting a grinding on the gears in and out so checked the Thrust washers (not in the sump) and this was next but not sure if at the very least that fork needs greasing or not.....no leaks that i can see though Link to comment Share on other sites More sharing options...
firebobby Posted July 9, 2011 Share Posted July 9, 2011 Is the clutch fork moving when you press the pedal. Link to comment Share on other sites More sharing options...
shadowbane Posted July 9, 2011 Author Share Posted July 9, 2011 yeah just a weird grinding when the peddle is down :/...thought i'd start with the Slave to see if it was doing it's job as it has benn replaced Link to comment Share on other sites More sharing options...
nang Posted July 9, 2011 Share Posted July 9, 2011 Sorry, but sounds like the clutch thrust bearing needs replacing. Gearbox out job. :'( Link to comment Share on other sites More sharing options...

shadowbane Posted July 10, 2011 Author Share Posted July 10, 2011 just started doing it....the clutch was close to the floor on chang overs anyway Link to comment Share on other sites More sharing options...
logicaluk Posted July 10, 2011 Share Posted July 10, 2011 stupid question but is there any free movement in the clutch pedal? my master cylinder wasnt returning all the way & this was giving a very low biting point.Dan Link to comment Share on other sites More sharing options...

logicaluk Posted July 10, 2011 Share Posted July 10, 2011 it was felt in the first movement of the pedal, most obviously shown with the tunnel cover off the slave didn't start moving till about 1/4 pedal travel.Dan Link to comment Share on other sites More sharing options...
shadowbane Posted July 10, 2011 Author Share Posted July 10, 2011 so to check...whip out the slave and press the clutch? Link to comment Share on other sites More sharing options...
logicaluk Posted July 10, 2011 Share Posted July 10, 2011 just pull out the gearbox tunnel & press the clutch, watch to see when the slave starts moving.Dan Link to comment Share on other sites More sharing options...
shadowbane Posted July 10, 2011 Author Share Posted July 10, 2011 yeah seemed to right on press. This is gonna be a huge job isn't it lol Link to comment Share on other sites More sharing options...
lancepar Posted July 11, 2011 Share Posted July 11, 2011 Before you do anything, do you have a return spring on the clutch pedal under the dash? 8) Link to comment Share on other sites More sharing options...

Dannyb Posted July 11, 2011 Share Posted July 11, 2011 Two things you should look out for . One is that the slave is pushed in fully before doing up the pinch bolt as there is a bit of movement there. Two if there is any wear in the clevis pin on the clutch peddle where it operates the master (under the rubber boot) or the holes are obling then that little bit of movement results in a lot of free play at the other end.

From the forum I learnt the missing return spring was essential.After fitting one I pushed the pedal to the floor and let it fly back unrestrained, after repeating this a few times the pedal bite returned to where it should have been with clear gear changes. Guess I was lucky. 8) Link to comment Share on other sites More sharing options...

lancepar Posted July 12, 2011 Share Posted July 12, 2011 Here is an image of the master cylinder. To get a full charge of fluid to the slave cylinder it is essential the piston in the cylinder is returned to it's resting position.If the internal return spring has broken or weakened or the linkage return spring is missing, the poor little spring inside the cylinder will struggle to overcome the effort of trying to return the heavy pedal and the piston, and will not return to it's resting position.So with the rubber boot removed there should be hardly any free in and out movement along the forked push rod to where it makes contact with the piston. If there is a lot, then the piston is stuck in the cylinder.HTH 8) Link to comment Share on other sites More sharing options...
