Engine Run-In Procedure - Engine
Dynamometer (14-03)
Measurements from these indicators and gauges must
be observed closely during all phases of the engine run-in
period. Engine measurements taken are:
• Engine speed
• Engine torque
• Lube oil pressure
• Coolant out temperature
• Fuel pressure
• Crankcase blowby
• Fuel rate (using Part No. 3376375)
To correctly evaluate the engine performance, this ad-
ditional measurement, intake manifold pressure (turbo-
charger boost), must be observed during engine run-in
phases.
Refer to the Engine Dynamometer worksheet on the last
page of this procedure.
NOTE: It is recommended to monitor block coolant pressure
during run-in to aid in early indication of a cooling system
problem.
