Due to the huge demand for photos (neilly) here are a few more.
This is the view once the timing chain cover was removed. Note the little oil pipe to the left just above the belt tensioner that comes from the alternator. This was secured by one of those crimped clips so had to be cut off and replaced with a jubilee clip.
I also ended up removing that cannister thingy me bob at the top of the picture cos it was getting in my way.
From the underside you can see where the new chain has to go.
Here you can see the slack in the timing chain once the tensioner is undone and the sprocket removed from the camshaft.
New chain, sprocket and bolt fitted.
Putting it back together was just the reverse but with lots of swearing and googling for torque settings and bolt tightening sequences, plus some more swearing and some more googling.
I know it's not the best how to guide but it was all done in bits and pieces as time allowed so documenting it was done on a best efforts, total time I reckon to be a good couple of days work.
