Engine Maintenance 9-26
Injection Pump Timing (except TK 486V Engine)
This timing procedure requires fuel pressure at the injection pump inlet. This can be accomplished by pumping the priming pump
by hand, or by using an electric fuel pump to supply fuel to the fuel pump inlet.
1. Place the On-Off switch in the OFF position.
2. Remove the round cover (plug) from the timing mark access hole on the front of the bell housing. The index marks on either
side of this hole and the timing marks on the flywheel are used to check the injection pump timing.
WARNING: Loosen all of the injection lines at the injection nozzles to prevent the possibility of the engine firing while it is
being rotated.
3. Remove the injection line for the number one cylinder from the injection nozzle and from the delivery valve on the injection
pump.
NOTE: The number one cylinder is the cylinder at the flywheel end of the engine.
