About to take on the timing belt challenge. Having read Haynes carefully I am have two questions. It's clear that the crank and camshaft pulleys need to be pinned in place throughout to maintain the timing. Haynes, having said (on page 2A-4) that there are only timing holes/slots on the crankshaft pulley flange and the camshaft sprocket, later says, on the same page, "insert ford tool No 303-732" through the slot on the fuel pump sprocket.
I'm very happy to lock the fuel pump sprocket in place too, if indeed there is a slot and corresponding indent for the respective tool (drill bit probably) to go into.
My question is, do I need to lock the fuel pump pulley? If so why? It's a high pressure pump and so does its timing matter?
Separate but related question. Haynes specifies camshaft sprocket bolt torque as: Stage 1 = 20nm. Stage 2 Angle tighten a further 50 degrees. What is this angle tightening about? Why not just have a tighter Stage 1?
Grateful for any enlightenment
