shercoman2k8 Posted April 21, 2010 Report Share Posted April 21, 2010 As title, trying to fix a friends bike, and for some reason, the clutch just will not bleed, atall... no clue why. Help guys! Regards, Jamie Quote Link to comment Share on other sites More sharing options...
ishy Posted April 21, 2010 Report Share Posted April 21, 2010 Make sure the adjustment on the lever is back enough to let the clutch plunger return , this could even be the problem in the first place. Quote Link to comment Share on other sites More sharing options...
shercoman2k8 Posted April 21, 2010 Author Report Share Posted April 21, 2010 Taken the adjuster right out, makes no difference. Had it bled perfectly at one point, but it just went... Now it wont return. Quote Link to comment Share on other sites More sharing options...
trialsnutterman Posted April 21, 2010 Report Share Posted April 21, 2010 Back fill it from the bleed nipple, it helps push any air locks out. Sometimes the seals swell stopping the oil getting through to the piston, this happens if you use the wrong oil, use DOT 4 only. Quote Link to comment Share on other sites More sharing options...

Tried back filling, seems impossible, so much resistance and I cant figure out why. Maybe the seals have swollen, im using DOT 4, not sure what was used before...

stork955 Posted April 21, 2010 Report Share Posted April 21, 2010 Gday, if it wont back bleed you have either a blocked transfer port in the master cylinder (the very small hole closest to the inner end of the m/c), or something is preventing the piston in the m/c from fully returning to the circlip. This will also block off the transfer port. It also pays to remove and check the bleeder nipple is not blocked, especially if it missing the rubber cap. You will only get swollen seals if you have put oil in a brake fluid system or vice versa. As far as I know Sherco's dont use oil, only brake fluid.

copemech Posted April 22, 2010 Report Share Posted April 22, 2010 It sounds as though your master cyl piston is not returning fully enough to open the backflow port. This may be due to dirt and or corrosion so disassembly and a re-build kit may be needed. You may be surprized what is under that rubber boot!
