you need a flywheel pin locking tool or a drill bit of the same diameter.
the camshaft has a locating hole about the 5 oclock position and the injection pump about the 5 oclock position.
the flywheel has a locating hole on it and this is located on the front of the engine down on the engine block just above the sump level facing the flywheel
hi rob dont think there is a injection pump high preasure pump
you are correct but it is still driven by the belt but i always pin them up or mark there position better to be safe than sorry.
