These are set using 3 locking bolts (8mm thread, about 70mm long) rather than by timing marks. The injection pump has 2 bolts that screw through holes in the pulley into the casting, ( the top one is approx at 1 oclock, the bottom one approx at 6) the cam sprocket uses one bolt that screws in similarly, (position approx 5 oclock) then mark the crank pulley with a couple of dabs of paint. Ideally there is a pin that should go through the block and into the flywheel, (behind the starter motor) if all is correct.
