help with bleeding the hydraulic clutch

Post by roadwanderer2 »



good morning guys. hope ya'll had a good thanksgiving. now to my question.....im in the final stages of getting my 1200 SEi all back together now and im having a problem with the clutch slave cylinder. is there a "how-to" article, or do one of you know a trick in bleeding the hydraulic clutch and clutch m/c? i can't get any pressure from my clutch lever even though i've bleed the m/c at the banjo bolt and on the slave cylinder itself. i was able to bleed out the m/c and i get no air from it. i've used a vacuum bleeder, i've gravity bled the slave cylinder, and still no action from the clutch lever. can the line be so full of air that its gonna take forever to get this clutch to bleed out?

If you have fluid all down the line and to the slave i.e. you pump fluid out of the slave with the vacuum pump), try doing a good old fashioned pump the lever/squeeze the lever/open bleed valve/close bleed valve/let go of lever a few times in a row. Sometimes I have had a clutch that would NOT bleed with a vacuum pump for some reason, but would bleed this way.

You might also want to try pumping and then squeezing the clutch, strapping the clutch lever to the handgrip overnight and see if that makes any difference.

I bleed mine off and on for 2 days. Used 1/2 quart of brake fluid (+) then a few days later had to bleed some more. :?

guys, im gonna go out to the bike this morning and im gonna bleed this thing out one way or another. in any event, its got to work eventually. if i can't get it to bleed out, when i take the bike back down to the "electrical gurue" i'll have him do it since he's done these before to other goldwings. he has one of those air vac-u-suc machines and he'll be able to get it working.

well, i have good news to report. after pumping and bleeding for the past hour, i FINALLY got the clutch slave working again and have a good clutch lever pressure. what i did was removed the bleeder screw from the slave cylinder and found it to be blocked. so i took one of my torch cleaner tips and cleaned out the bleeder screw, put it back on the slave cylinder and continued to bleed the clutch slave and it finally got the pressure back into it. i ALSO found that the front brake lever had no pressure in it when i squeezed the brake lever due to the master cylinder being empty, so i did the same thing to the caliper bleeder screw. it was also blocked up so i cleaned that also, put it back onto the caliper and bled out the front brake. now both are working perfectly again.

i want to thank you guys for all your tips and suggestions to me. they definitely helped me and got this problem solved.

stuart.
