49.2.2 Alternate method
In the fuel flow method, the delivery valve has to be
removed. As a result, there is a good chance for dirt
particles to get inside the fuel injection pump. In this
alternate method, however, it is not necessary to
remove the delivery valve.
1. Disconnect No. 1 fuel injection pipe at the fuel
injection nozzle (cylinder head).
2. Prime the fuel system.
3. Slowly turn the crankshaft clockwise until fuel just
swells at the free end of the injection pipe and, at
that instant, check the position of the IT mark with
respect to the mark on the gear case. This timing
is approximately 1° retarded. Take this 1°
retardation into account when making a shim
adjustment.
