INJECTOR PUMP
5. Slowly rotate crankshaft clockwise until timing
mark on pulley aligns with reference point on gear
case cover (TDC), Fig. 5. Note dial indicator
reading.
NOTE: Do not rotate crankshaft past TDC. If
crankshaft is rotated past TDC rotate
crankshaft back to ‘‘0” and repeat
procedure.
6. Refer to timing specification tables on page 3 for
correct specification by engine model and type or
code number.
If indicator reading is within specification, injector
pump is properly timed. Proceed to step 6.
If indicator reading is not within specification, see
procedure for adjusting injector pump timing.
