How do I stop oil leak from the chain tensioner (1980 XS1100 SG)

[DEEBS11]

I agree with soccer4m and the process he described. I don't see it as being the gloom and doom that is being made out to be. Back on the old forum, I couldn't begin to count the number of guys that successfully did it. Yes, there were a few that had problems. Imo and from experience, with an ACCT from the multitude of Yamaha bikes/ATV's that can be found on ebay, the ACCT is the ticket. The confirmation bias strongly favors those who have been successful.

With that...

Can you explain more how to R&R without removing? That could be a very helpful process.

The leaking was the genesis of putting on an ACCT. I don't recall reports of leaking once installed properly. And did I say, never need to adjust again?

Bonz, are you saying you agree that the procedure should be done at TDC instead of C? I think we corrected this that the setting is "C" and not TDC.

"C" is correct. I have edited my post to reflect that.

TDC versus C had already been corrected before I posted but I see where the confusion could come from. I should have made the note that while agreeing with the process, C is correct.

I stand corrected, use C for the install of the ACCT,, according to the manuals,,however I have used TDC for a few ACCT installs and zero issues, I just make sure the engine does not rotate as the cam chain is corrected to exact tension by the ACCT.....have fun,,,,Mike in S.Diego and Pa

It has been reported that the OEM tensioner is prone to slipping out of adjustment during heavy engine braking. The ACCT can not do this because of its one way ratchet mechanism.

Being completely honest, I don't know what the difference would be in a C or TDC with respect to removing a tensioner and replacing it now that it has come up. Can one of the collective share the mechanical importance/difference with respect to a tensioner replacement?

Top dead center on compression or C on the exhaust stroke at the top, would make no difference because the engine isn't firing to try and push itself back down. At least that's how I see it. However, I have used C like the manual calls for.
