55LDE Posted September 22, 2009 Report Share Posted September 22, 2009 i just changed the clutch in my manual 4ac with a new excedy clutch kit and since we put it together the gear box is making this loud squeel on idle and when u push the clutch in the noise goes away, so i thought its the throw out bearning so we took the box off and put another bearing in and its still making the noise :-( any ideas? we have used a brand new bearing and a old bearing and both make the noise. before the clutch change it was working all good.

Evan G Posted September 22, 2009 Report Share Posted September 22, 2009 (edited) hydralic or cable clutch pedal? did you machine the flywheel? did you change the spigot bearing? (sits in the crank) Edited September 22, 2009 by Evan G Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted September 22, 2009 Report Share Posted September 22, 2009 Could be spigot bearing.. If you push the thrust bearing off the pressure plate by pushing on the arm, does it stop? That would stop the thrust bearing spinning, but leave the spigot running with the gearbox shaft in it. Not much else in there- with the clutch up the input shaft spins in the spigot, usually the thrust spins on the pressure plate (shouldn't do really..) and the input shaft turns the layshaft in the gearbox.. there's oil in box I assume!! I always grease the end of the input shaft where it goes in the spigot, and the splines where the clutch plate runs, and the yoke where it pushes the thrust bearing.

kiahn Posted September 22, 2009 Report Share Posted September 22, 2009 sounds like the thrust bearing, could be just touching the pressure plate fingers which would cause it to squeel Quote Link to comment Share on other sites More sharing options...
Evan G Posted September 22, 2009 Report Share Posted September 22, 2009 yea but I'm thinking the clutch cable hasnt been backed off to conpensate for the extra meat on the new clutch. have you driving it yet? around the block? Quote Link to comment Share on other sites More sharing options...
Evan G Posted September 22, 2009 Report Share Posted September 22, 2009 also he maybe got clutch dust on the spigot bearing there for sezing the spigot bearing? one thing ive noticed at work with mercedes vans is even though you aligned the clutch with a dummy shaft the pressure plate doesnt sit on the flywheel properly? like the diaghram fingers stick up and half don't? even though you slowly nip all the bolts up evenly that got me to swear wtf a million times. simple fix, remove and refit LOL fixed the problem :P Quote Link to comment Share on other sites More sharing options...
55LDE Posted September 22, 2009 Author Report Share Posted September 22, 2009 hydralic or cable clutch pedal? did you machine the flywheel? did you change the spigot bearing? (sits in the crank) Hydraulic. Yes Flywheel machined. No i didnt change that bearing, just the throw out bearing. This was working perfectly with no noise before the gearbox was removed.

55LDE Posted September 22, 2009 Author Report Share Posted September 22, 2009 we did find when we took the gearbox off one of the clips that holds the throw out bearing onto the fork had come off. We put this back on and bolted her back up and was running good for about 5 min then the noise came back. could be the clip has fallen off yet again not sure :P Quote Link to comment Share on other sites More sharing options...
philbey Posted September 23, 2009 Report Share Posted September 23, 2009 That's what I was thinking, one of the clips getting dodgy and coming off. Spigot bearing will make noise when the clutch is in (ie foot on it) because that's when it's under load. Quote Link to comment Share on other sites More sharing options...
55LDE Posted September 23, 2009 Author Report Share Posted September 23, 2009 Where would i get these clips from? Quote Link to comment Share on other sites More sharing options...
