Karl's Clutch is Kaput!

Karl The Motorcycle, (KTM for short) a 1290 SAR, need a new chain guide installed. I decided to undertake what seemed to be pretty straight forward repair.

The process involved removing the clutch slave cylinder. I put it aside without loosening any fittings on the hoses.

I put everything back together and was getting ready to take him for a spin, squeezed the clutch, and, Crap! No pressure at the lever.

Being unfamiliar with this new fangled clutch technology, I am stumped.

Help an old guy out!

Did you happen to remove the rod between the clutch slave cylinder and the clutch, and forget to reinstall it? Is the clutch slave cylinder fully seated? Bleed the hydraulic clutch line - same procedure as bleeding a brake line.

Or, if you pushed the slave back, you may need to squeeze it a number of times to get it back out far enough.

I did not remove the actuator rod, however I did find a needle roller on the floor, but I don't think it is causing the issue of no pressure. I do need to find the place the roller goes though.

I will bleed the clutch and see if that helps.

This is a chore turning into a project.

Thanks! Dusty

The piston seems to be out as far as it will go. It is resting against the internal retaining ring. I am afraid I may have busted a seal and am going to have to buy a new slave cylinder as it is leaking now.....

I am going to bleed it tomorrow and see if that helps things out.

Crap!

Bled the clutch today, works fine!

Thanks for the input!

Lesson learned. If it is hydraulic, bleed it first!

Thanks again! Dusty
