Dear Forum,

Please find below a pic of my bottom.......chain tensioner :!:

Please could anyone explain how I am supposed to insert my allen key to either retract or deploy this tensioner? I had to undo the set bolts and catch it to get it off :!: :!:

Better still, could someone please confirm that my best course of action is to drill and tap a hole to allow me to access the mechanism with an allen key :?:

Best regards,

Ray


 
That's the late type tensioner and they don't have that facility. You need to set the adjuster so it's locked in the pad section, and then there's a plastic spacer that should come with a new one that you place inbetween that part and the body when you install it. Once it's in place you remove the spacer, and lever the pad back into the body to trigger it into operation.

If you haven't got the spacer, fit it all together than hold it in place with a couple of cable ties, and then when you're ready, cut the cable ties off.
 
My thanks to Harvey, Michael & James Radcliffe

How do I remove the 3 steel 'bolts' (they are circular with one flat side) from the front of the Timing Chest, please? Presumably, one of these will allow access to the upper of the bolts securing the top chain vibration damper pad (I cannot get the Auxiliary Drive Chainwheel off without first lowering the pad)?

There really does not appear to be much in Haynes to explain how to strip out the Timing Chest?

They are actually alloy plugs which have a recess for a neoprene O ring , and are a tight intererence fit with a corresponding annular recess in the front of the block . In my limited experience, getting them out is a real swine , and your best bet is two angled levers ( like the old bent screwdrivers Triumph used to include in their toolkit , or small tyre levers ) inserted under the lips of the plugs

Christopher - Thank you......I had one hell of a job getting the plug out of the intermediate chain wheel access - I figure that when the O-rings became old and brittle and leaked, instead of simply replacing the O-ring, previous owners must have hammered the plug in further, thereby crushing the O-ring!

Best, Ray

That's exactly how I do it - two small tyre levers and walk them out gradually. They can chip very easily if you're not careful. Not the end of the world as long as the sealing face isn't broken, but does look unsightly!
