Very slight oil weep

Post by darkember »

I have noticed a very slight oil weep. It seems to be coming from the threaded section of my APE manual CCT bolt after the locking nut. This is only occuring on the rear cylinder, front one is fine. I can remember something I read about using PTFE or teflon tape infront of the lock nut, is this correct?

2nd question. Is it ok to back off the manual CCT to apply this tape without upsetting the cam chain position?

Many thanks

Don't just undo the tensioner, the rear cylinder has to be in the correct position, just as though you were replacing cct's
See the thread in Workshop, the sticky at the top.
You'll need to remove the tank and lift the rear cam cover to be sure that you've got the engine set at the correct rear top dead centre.

THEN you can unwind it, and some silicon sealer on the bolt thread before winding it back in will do the trick.
Use plenty, wipe it all off afterwards.
It's not falling off, it's an upgrade opportunity.

This is becoming a little confusing I've read posts on people adjusting them while the bike is running, I cannot believe they would be removing the tank & rocker to do this.

I am not suggesting removing the cct completly only backing it off 2mm to get some tape behind the locking nut. Also the post as far as I see only refers to auto cct's & not the manual versions.

Please advise as I dont want to do anything detramental. Thanks

them ape tensioners..... dont just rely on the o ring & nyloc nut.
they have to be FT - FKIN TIGHT

mine came undone on me twice & trust me it is not fun trying to retension them on a running engine when they are hot.

tony is right.... do it proper matey or live with the oil leak.
its easy to lift the rear cam cover.
if you want to save work you could remove the plugs and feel for compression with your finger in the plug hole as you turn the flywheel to RT.
much safer to do it proper though!

you need threadlock on the adjusting bolt and the locknut, then get the locknut as tight as possible, dont just nip it up on the o ring.

the guide on here is applicable to auto and manual tensioners - same procedure for fitting applies to both.

Thanks for clearing that up, I think I may live with the weep for a while until I get to know the machine better :thumbup:

Just another query is why did APE use such a coarse thread on the tensioner would'nt a finner thread type be more efficient for locking the locknut down?

Yes, a finer thread would have been infinitely better.

But then the same comment can be made about most of the threads on here......

If it helps, I found I had very slight oil once, and I wept also.

Just after the shops closed on a Bank Holiday, it was...
