    Belt and braces really, like doweling the flywheel or strapping the freeze plugs - hopefully you'll never need them but a bit its a bit "safety net" I guess.

    Out of interest, what are peoples preferred method of cam pulley counter-holding while torquing the bolt, since there are no pins etc. I have previously used an old cambelt to hold it steady but its not ideal

      Set of molegrips on the exhaust cam on a cast section to torque the cam pulley up. That way the torque is a clamping load and you are not putting strain on the keyway. Aftermarket cams and later engines come with a casting to put a spanner on the cam itself.

        did you get what appears to be half a key?.....
        I had already purchased one from TPS.
        When "Santa" brought my adjustable gears from Rosten the key looked tiny....about half the size of a stock one...

          Yes, sounds like the one I got. Might not be 100% necessary, but I'll sleep better knowing it's done
