Connect testing device 60462800 (3) to injection pump (4). Make sure side connections (2) are
tightly locked.
Loosen the pressure gage connection, and crank the engine until trapped air is removed from the
system.
Tighten pressure gage connections.
The pressure gage can be damaged if the engine is cranked
beyond the gage limits. Failure to heed this caution can
damage equipment.
Slowly crank engine by hand. As the engine is cranked, read fuel injection pressure on the gage.
Injection pressure should be 4351 to 5076 psi (300 to 350 bar). Stop cranking engine and
observe whether pressure is maintained. If pressure drops below 3650 psi (250 bar) within 10 to
15 seconds, then injection pump is not in working order. Notify rear intermediate maintenance.
Remove testing device 604 628 00 (3).
