Make sure the engine has cylinder No. 1 at TDC.
The barring gear inserts into the flywheel housing and
engages the flywheel ring gear. The engine can then
be rotated by hand using a 1/2 inch ratchet or breaker
bar.
Injection Pump - Timing
The injection pump also has a timing pin, located in
the governor housing, to position the pump shaft to
correspond with TDC for cylinder No. 1.
