Title: Clutch replacement info
Post by: wmax351 on January 11, 2013, 01:05:56 PM

My K75's clutch is at the end of its adjustment range. Still holds well enough, but not sure how long that will be true. Motobins has deal on a clutch, the diaphragm spring, and the pressure plate for 41 pounds sterling, so I may buy it and replace it when I feel like a project.

My question is: should I do the throwout bearing while I'm at it?

I wouldn't necessarily do that. I would however replace the seal, o-ring and nut behind the coupling and if it is a high mileage bike have a good look at the bronze bush in the engine shaft, where the coupling push rod rides in.

I wouldn't bother with it either.

I figured I would do the O-ring and nut. Should I do the Rear Main Seal too?

Hey Wmax, I'm afraid that I'm running out of clutch as well, but I'm not sure how to know without opening up the transmission.

Is the clutch about toast once you're out of room on the barrel adjuster on the clutch lever? I may be going on a 3,000 mile trip soon and fear that I don't have time to purchase and replace mine.

The barrel adjuster on the handle bars is not how you adjust clutch free play its for initial adjustment of the cable on the lever at the back of the transmission. Free play is adjusted with the bolt and jam nut at the clutch rod.

This video does a very good job of explaining how to adjust the clutch.
