Purpose of Yamaha quick gasket on slave cylinder bolts

Noticed my clutch slave cylinder was leaking while I was working on my carb/petcock problem. The Yamaha service manual says to use quick gasket on the bolts for the slave cylinder. What is the purpose of using that on the bolts and is it necessary? Thanks.

Sounds like some sort of thread lock substitute. I have not used any thread lock on the clutch slave bolts, just proper torque...

Thanks for the reply. After further review my slave cylinder is pitted and needs to be replaced. It's just one thing after another. I feel like I am keeping RPM in business lately!!

The rebuild kit I bought from RPM before I realized I just needed to replace the whole assembly came with a small seal. I think it's #24 on the exploded clutch diagram, it says oil seal. Can I pull the push rod out of the left side of the engine to replace that seal with out causing issues? I have never had a clutch apart before but I see on the diagram there is a ball on the other end of the pushrod.

Hi Guys,

I'm hoping for a quick, simple answer to this question: "Can I pull the push rod out of the left side of the engine to replace that seal with out causing issues?"

I'm about to replace the clutch pushrod seal but I'm worried about the ball falling out of place. I expect the seal is easier to pry out with the pushrod out of the way.

Thanks for any advise you can offer.

Cheers

You can pull the clutch push rod out with out any issues. Members have reported starting the engine with the clutch slave off (Search the forum for spearing the cat)  :rofl2:, The rod shoots out followed by a stream of oil, the amount depends on how quickly the dumbshit gets the engine shutdown. No reports of losing the ball have been posted that I know of. My personal rule when doing clutch work starts with moving the FJ key from the bike to inside the house. Rumor has it Father Pat's cat will still not go in the garage... So feel free to pull the rod out, clean it, change the seal and reassemble.

Thanks Monkey.. That is exactly what I wanted to know. I've read many times about spearing the cat and it still cracks me up reading it now. I took your advice from a while ago to remove the key while doing this. Now I just have to remember why I left the key out :good2:

I would love to know the background to this.... (popcorn)
I did a bit of searching for the original post using 'cat spearing' (start, slave, pushrod, clutch, cat, etc.), but can't find the original story.
Any chance someone knows the original thread link?
Or was this from the Yahoo days?
