I have just had a go at removing the injector pump and failed. The nuts come off and the pump moves about 1/8 inch, but then stops dead as if mechanically connected to something inside. Tried rotating the engine at the same time as pulling on the pump, still no joy. I guess the end casing will have to come apart to disconnect something inside.
Anyone know if a manual or just an exploded diagram of this engine is available online? I have searched but have yet to find anything useful.
