Jim,
I have only done this with the radiator and fan removed. The nut on the
crankshaft takes a 1-5/8 inch socket. A 20 " lever/handle gives you plenty
of leverage.
Always turn crankshaft clockwise as you are facing the engine. If you miss
the mark, always approach the timing mark in a clockwise direction to
eliminate the gear backlash.
There are three timing marks on the damper, if your engine is turbo
equipped, use the top mark, which is 20 degrees BTDC, if naturally aspirated
use the next one down (25 deg). The engine crankshaft makes two turns for
the pump to complete one cycle. There are two timing windows on the pump,
but you know that by now.
