Engine Run-In Procedure - Chassis Dynamometer (14-04) Section 14 - Engine Testing - Group 14 M11 Page 14-46 Lubricating Oil Pressure Use Pressure Gauge, Part No. 3375275, to measure lu- bricating oil pressure. Install the pressure gauge to the main oil rifle and observe the oil pressure. Low Idle (minimum allowable) 69 kPa [10 psi] At 1200 RPM (minimum allowable) 207 kPa [30 psi] Coolant Pressure Use a vacuum gauge to measure engine coolant pres- sure. Maximum coolant pressure (pressure cap removed) with closed thermostat is 317 kPa [46 psi] at rated RPM.
Engine Run-In Procedure - Chassis Dynamometer (14-04) Refer to Chassis Dynamometer - Operation, Procedure 14-03, for general operating procedures and safety pre- cautions. Operate the vehicle in a gear that produces a road speed of 90 to 100 km/h [55 to 60 mph] at maximum horsepower RPM. Install a Compulink™on CELECT™engines for monitoring engine performance variables, system pressures, tem- peratures etc. Monitor and record the following measurements during run-in: Lubricating oil pressure Coolant temperature Fuel pressure Engine Torque Crankcase Blowby Engine speed (RPM) Fuel rate (Use service tool, Part No.
