How do I time the injection pump, cam, and engine block?
To time the VW diesel motor, you need to do a mechanical timing and an injection pump timing. Don’t let this scare you. Read through your Bentley or other auto manual a couple of times and you will do fine. For the mechanical, you need to lock the cam in place at TDC to get the valves timed with the crank. You do this with a VW lock plate tool at the back of the cam. You need to have the engine at TDC ensuring your number one piston is at TDC. If your timing the engine with an assembled ACME kit on a Samurai transmission, then you use the original suzuki timing hole in the transmission to line up the flywheel at its TDC mark. If you have a VW tranny on the motor, then you use the VW flywheel marking (Sidekick/Tracker/Toyota transmission conversions are timed using the VW bellhousing and flywheel before the motor is installed in your vehicle). Once you have the engine and head timed at TDC, then do the injection pump. To time the injection pump, you will need to put the pump sprocket at
