Clutch slave cylinder rebuild question.

[Fiddlesticks]

On the basis that there are no stupid questions - I'll be the exception that proves the rule.

I've just got the clutch slave cylinder rebuilt and back on the bike, but it won't go into gear with the engine off.

Reasons I can think of:

 

1. There's no oil in the engine. Put some oil in, start the bike and it'll be fine.
2. I've stuffed up the rebuild somehow.
3. Air in the hydraulics. The vacuum bleed tool is great, but it pulls air bubbles through the thread in the bleed screw.

 

Thoughts?

I agree with @Mississippi Bullfrog but prior to starting you should be able to go through the gears by turning the rear wheel by hand just to be sure.

You did refit the actuation rod ?

Thanks Mickly, that would be just like me!  No, it's fitted.

 

It's trying to change gear (neutral light is going off when the gear lever is pushed down).  Just not quite clicking in.  I'll have a fiddle later on.

I had dropped the oil for an oil change anyway, but I read somewhere you probably need to do the oil if you've had a leaky clutch cylinder as the DOT4 fluid can contaminate it.  Didn't want to re-add it too soon.

Thanks. It works!

Much happier after a few pulls of the lever and getting the back wheel on the ground. Very smooth gear changes.

Other than a bit of oil on the chain it's done. Next step MOT.
