Seized cambelt tensioners

See many cambelt adjusters set wrong or failed by seizing, there can be different reasons for this but either way its not good for the belt or your wallet!

 

The zed below was in for a cambelt replacement, no drama, sounded ok so stripped it down.

Once stripped it was clear the auto tensioner was stuck and not applying any tension on the belt.

The belt had as normal streched since installed but without any tension was so loose you could pull the belt off the pulley.

The adjuster can be seen here to be closed, it should be wide open with no belt on.

 

The bizzare thing with this and one`s I have seen before was that the engine was quiet with no indication if a problem of this nature, easy to get caught out.
