RUN-IN PROCEDURE FOR REBUILT ENGINES (WITH A DYNAMOMETER)
The following procedure must be followed when using a PTO dynamometer to Run-In the engine. The dynamometer will control the engine load at each speed and will remove stress on new parts during Run-In. During the Run-In, continue to check the oil pressure, coolant level and coolant temperature.
1. Disconnect the wire to the electric shut-off on the injection pump so that the engine will not start. Crank the engine for 30 seconds until there is oil pressure, then reconnect the wire.
2. Remove the air from the cooling system at the temperature sending unit or aftercooler, if equipped.
3. Run the engine at 800 RPM for 3 to 5 minutes. The oil pressure should be a minimum of 1009 kPa. Check for leaks.
4. Increase the engine speed to 1200 RPM and increase the test load to 25% of the rated load. The coolant temperature should be a minimum of 70°C. Run the engine for 5 minutes.
5. Check the blowby. If the reading is steady, increase the engine speed to peak torque speed and increase the load to 50% of the peak torque load. Run the engine for 5 minutes.
6. Check the blowby. If the reading is steady, increase the engine speed to full throttle and increase the load until the RPM falls to rated torque speed. Run the engine for 5 minutes.
7. Check the gauges. If the readings are within limits, increase the load until the engine speed decreases to the peak torque RPM. Run the engine for 5 minutes.
8. Completely remove the load and reduce the engine speed to 1000 RPM. Run the engine for 3 to 5 minutes.
9. Shut off the engine.
