e:: Remove the injection pump gear by
removing the nut and lock washer that secure
the injection pump gear assembly to the
injection pump shaft. The injection pump
gear assembly is made of three pieces; the
flange, the gear, and the transfer pump cam.
Do not loosen or remove the four bolts that
fasten the gear to the flange because that
changes the factory-set timing. The EPA
certification is based on the factory-set
timing. If the factory-set timing is changed,
the EPA certification is void.

4. Record the injection angle marked on the old
injection pump (see the following photographs).
The injection angle mark is located on the side of
the pump facing the engine. The injection angle
mark on the pump does not use a decimal point.
Add a decimal point before the last digit of the
injection angle mark to get the injection angle. The
injection angle mark in the following photographs
is 67. That equals an injection angle of 6.7 degrees.
