Cam chain tensioner small oring behind jam nut

[roy826]

Mine is leaking can I simply loosen the lock nut remove the threaded piece and install a new oring onto it and reassemble? still on the engine of course. It is not leaking anywhere but this oring and I have purchased one from Suzuki. I did a search but seems nothing I came up with has just this part covered on a how to.

Yes I have but it’s not real clear on the one small thing I need to do. Or maybe I just didn’t follow it very well. Sounds like removing the jam nut and threaded part is simple if it’s left on the bike. Nothing can jump time?

"One small thing I need to do"...I think it's what "not to do". While it's loose (or out) don't do anything to rotate the eng. Don't touch start button, don't turn rear wheel, till all is back in place & locked down...Just my opinion

I was planning to not touch anything while apart except replace the leaking oring and reassemble. Just needing a confirmation I can do it by just removing the jam but abs center threaded screw which holds the oring. Then put it back just like I took it apart. I know plenty about the timing of an engine. Just do not know much about this 40 year old can chain tensioner design.

You'll do yourself more good to just follow the entire guide and replace everything. Like you said, it's 40 years old and could probably stand a new gasket, o-rings, and maybe removal of the pit that has likely developed on the pushrod
