I need to rebuild my clutch master cylinder...

I tried looking on the how-to but couldn't find anything. I have a 1987 vfr750 and i need to rebuild the clutch master cylinder but i need a how-to on how to do it. I just purchased the rebuild kit today. If somebody could help me out asap then i would greatly appreciate it!!!!

 

:welcome:

For godssake man, it's in the blinkin' service manual...........you've read it, right ??

It's got pictures too !!

 

Take a look at this. It is pretty straight forward. I just rebuilt it on my 750 two years ago. I only ended up replacing #9, #12 and #18. The hardest part is bleeding the clutch when you're done. I definitely recommend using a bleeder for that.

 

I'm doing the same thing on my 87 750, and noticed there's a diagram in the service manual that shows the piston seal on the oil seal (outer) side of the piston. That's an error, right? The piston seal must go on the spring side of the cylinder, correct?

Is bleeding a clutch system exactly like bleeding brakes?

 

How does your diagram look compared to the one above? Can you reference the part number you're talking about? It is hard to visualize.

Bleeding the clutch is like bleeding the brakes. If you're going to do it manually, then I hope you have a lot of time and patience. I would definitely get a bleeder.

 

The part numbered "12" in this diagram, the piston seal is the part in question...in my 86-87 manual the diagram must have it wrong, showing on the other side of the piston. Yet, the black and white photo in the manual shows it correct. I'm not too worried, I'm almost positive the piston seal goes opposite the oil seal. I just thought it unsettling that the shop manual would have an error like this.

I put it all together and it didn't take too long to bleed. Air trapped at the master banjo bolt, but that's all. I did it by hand according to the shop manual.
