TM 5-3810-307-24-2-2
To be able to unload the compressor, connect a source
of compressed air to the unloader (1). This air line must
contain a valve between the source and the unloader.
NOTE
All air compressors manufactured
by
Cummins Engine Company, Inc. must
be
loaded during engine run in. All
air
compressors must be unloaded during
the
engine performance check.
NOTE
The
compressed
air
load
in
the
accompanying illustration must be attached
to the air compressor outlet (2).
To provide a load on the air compressor, connect an air
tank to the compressor outlet (2), using steel tubing or a
high temperature hose (1).
Install an air regulator (3) that can maintain tank air
pressure of 345 kPa to 517 kPa [50 psi to 75 psi] at both
the minimum and the maximum engine RPM.
260C [500F]
Hose Temperature (Minimum):
Inspect the voltage rating on the starting motor before
installing the electrical wiring.
Attach electrical wires to the starting motor and the
batteries, if used.
NOTE
If another method of starting the engine is
used, follow the manufacturer's instructions
to make the necessary connections.
Engine Dynamometer Test - Engine
Run-In (14-02)
The engine run-in period allows the tester to detect as-
sembly errors and to make final adjustments needed for
performance that meets specifications.
NOTE
The amount of time specified for the following
engine run-in phases are minimums.
Additional time can be used at each phase
except engine idle periods, if so desired.
