SEAL-O-RING 6E0410 - Caterpillar

Note: After the engine has been installed or rebuilt, carefully monitor the engine in order to detect any unusual performance.Warm-up
Operate the engine at low idle for two to three minutes. Allow the jacket water temperature to begin to rise before increasing the engine rpm. Note: More warm-up time may be necessary when the ambient temperature is below −18 °C (0 °F).
Check all of the gauges during the warm-up period.
Make another walk-around inspection. Inspect the engine for fluid leaks and air leaks. The time that is needed for the engine to reach the normal mode of operation is usually less than the time that is needed for a walk-around inspection.Engaging the Driven Equipment
Ensure that the gauges are in the normal ranges for the engine rpm.
Apply the load. Begin operating the engine at low load. The engine will reach normal operating temperature faster when the engine is operated at rated rpm and low power demand. This procedure is more effective than idling the engine with no load. The engine should reach normal operating temperature in a few minutes.
After the temperature gauges begin to rise, the engine may be operated at full load.
Continue to check the gauges and the driven equipment.
