    Hi,
    Below are 3 pics of an auto-tensioner from my parts bike motor (XJ750P 84).
    The bolt on the end holds the spring tension against the tensioner shaft which keeps the shaft pressing against the rear chain guide. The little latch retains the shaft in the furthest out position as the chain gets stretched.
    Hope it helps.

    "manual" cam chain tensioner, dissected:

    [​IMG]

    On your bike it will be mounted on the back of the cylinder block, as in Bushy's photos.

    You tell the difference between the automatic one (as pictured by Bushy) or the manual one (as above) by the presence or lack of the adjuster locking screw on the side of the unit. It is shown at the top right in my pic (ignore the arrow, that was about something else.)

    When you look in from the right side of the bike, you would see the locking bolt/nut. If you don't see one, it's the automatic style.

    hey guys thanks for this forum you do all rock indeed. however I was wondering if anybody had an pic of the auto-tensioner dis-assembled






    proud new owner of an 83 750, maxim and of course it sounds like the world is coming to an end at 5000 rpm otherwise she is a beast. using an Automotive Stethoscope (or a long bladed screw driver) with the bike at 5000 rpm you easily hear it is coming from the chain. and I am keeping my finger crossed and hoping that just cleaning the adjuster will fix her. I do not want to take the heads off as this is my sole means of transpo right now
