If you remember when I started stripping the bike I found that the chain tensioner had a jubilee clip around it, at that point I pressed the protruding rod and the tensioner appeared to work fine, well I'd been riding the bike and all was ok.

Well, as we are getting near to fitting the head and new chain I thought I better look a bit closer at the tensioner, I decided to remove the cap nut so that I could check the threads and have the body aqua blasted.
Now I know why the jubilee clip was fitted, in the past the thread had been broken, the cap was on by no more than two threads.
And no I didn't break it, it's an old break.
Time to buy a new tensioner....
