The next task is to remove the chain tensioner. First with a 12mm hex socket remove the outer plug.
Once removed take out the spring that will become obvious, then with a 17mm hex socket remove the inner retainer (I use a piece of 17mm hex bar and a 17mm socket as shown)
Next remove the Electrical and Vacuum lines from the cylinder head. Also undo the Jubilee clips from the interconnecting pipe if you have not already done this. Note mark the Vacuum line positions.
