Engine Run-In Procedure - Chassis

Dynamometer (14-06)

NOTE: Refer to Chassis Dynamometer Operation, Proce-

dure 14-04, for general operating procedures and safety

precautions.

NOTE: Operate the vehicle in a gear that produces a road

speed of 90 to 100 km/h [55 to 60 mph] at maximum horse-

power RPM.

Monitor and record the following measurements during

run-in:

• Compulink (install on CELECT™ engines)

• Lubricating oil pressure

• Coolant temperature

• Fuel pressure

• Torque

• Blowby

• Engine speed (RPM)

• Fuel flow (use service tool, Part No. 3376375)

Refer to the Chassis Dynamometer worksheet on the last

page of this procedure.

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.

Obtain CPL number from the engine data plate and the

fuel pump code from the fuel pump data plate.

Engine performance specifications and fuel system cal-

ibration values are listed for specific engine CPL and fuel

pump codes in the following publications:

1. Fuel Pump Calibration Values, Bulletin No. 3379352.

2. Injector Parts Flow and Cross Reference, Bulletin No.

3379664.

3. Engine Data Sheets

4. N14 Troubleshooting and Repair Manual, Bulletin No.
