Use the No. 1 intake valve to make sure the engine is at top
dead center (TDC) on the compression stroke for cylinder
Fabricate a timing mark pointer for the front of the engine.
This can be done by forming a piece of wire that can be
tightened under one of the gear cover capscrews. Sharpen
the wire at the vibration damper end so that it comes to a
point for better accuracy.
Attach a degree wheel or degree tape to the front of the
Line up the TDC mark with the pointer.
The degree wheel/tape should measure to an accuracy of
at least 1 degree.
Install the fuel injection pump according to the procedures
for a new fuel injection pump installation. If the fuel injec-
tion pump is already installed, continue the procedures.
