This paragraph describes run--in schedules for overhauled or rebuilt engines prior to being placed in service. En-
gine run--in is performed after rebuild to assist in breaking in new parts, to detect faulty assembly, to check for oil
leaks, and to determine whether an engine will operate satisfactorily when installed in vehicle.
Preparation for Run--in
Engine leak test should be done before run--in. Refer to
WP 0017 00.
Couple engine to suitable load. The load may be a water brake or electric dynamometer.
Lubricate engine by forcing engine oil under pressure into lubrication system. This will ensure adequate lubrication
to engine parts until oil is circulated under pressure from engine oil pump. When prelubrication equipment is not
available, fill crankcase with proper grade oil (TM 9--2350--292--10). Using engine starter, crank engine until pres-
sure gauge begins to move while holding fuel shutoff in the off position.
Connect external source of fuel supply to engine. Connect same type air cleaners that are used with engine when
installed in vehicle. Air intake should be located so that only cool, fresh air will be inducted into engine. A means
must be provided for conducting exhaust gases and cooling air from engine to avoid recirculation through engine
Provide a suitable external source of 24--volt direct current electrical power for starting the engine. The engine is
equipped with a low--voltage protective module so starter will not operate below 12 volts.
