Clutch bleeding

[Siggy79]

Refitted my clutch lever and master cylinder today, been bleeding for bloody ages, but can't see the push rod moving at all, any advice please?

It's a bit of a knack bleeding the clutch, as with moveable parts in the engine area, there is a lack of back pressure.

Try zip tying your clutch lever back against the handlebar overnight, that should allow any air in the system to work its way back up into the master cylinder - and then try bleeding again tomorrow

i remove the slave cylinder assembly then remove  the cyclinder cover.
i then use a G clamp to hold the cylinder in while bleading it as your not trying to move the whole clutch assembly while bleading the system.
seams to make everything much easier as your only moving fluid through the hoses and slave cylinder rather than moving the whole clutch .

Ok, I'll go and zip tie it overnight and try again, I could do with cleaning around the sprocket etc, so will try the g clamp as well, I should have asked first, been pulling on the lever for ages

Good luck buddy let us know how you get on - here to help!!!

I changed my clutch line today and didnt think there was much of an issue
I pumped the lever while watching for air bubbles once the air bubble stopped I removed the bleed nipple and pumped the lever -  once I heard suction at the slave cylinder I refitted the nipple and started to bleed - came up very quickly
Hope this helps

just remember the slave cylinder cover

Tried all of the above but I then noticed black ish fluid coming out, take it my slave seal must be f**ked, as I've done the master cylinder, can you just replace the seal or do I need to get a new assembly?

[seth]

you can get replacements really easily and its very straight forward to change them
also check the hoses as they can brakedown over time .

good luck

Ive a spare clutch line here if you want to try it

Great I'll get a seal, I have hel lines so there ok. Once the seals done it will be ready for the road again after a full rebuild/powder coating the frame.

Siggythis was something Kja.busa posted up on the old org

Can help with stopping clutch fluid discolouration. Just thinking if you are replacing your slave cylinder seals this may be worth checking or considering at the same time?

When I started fitting the smaller-bore braided lines to my bikes, I too had sods own job bleeding, so I bought one of those hand held brake bleed  vacuum pumps, FAN_BLOODY TASTIC!!
Pipe from nipple to collector-tank, pipe from tank to pump, open nipple & build up the vac, sqidillions of bubbles, then they stop, job done, I can bleed ANYTHING in a few seconds now!!
Just keep an eye on the rapidly diminishing fluid from the reservoir.

Absolutely agree with that Lawrie, one of the better tools I've bought too (I got the Sealey one - works really well)
