Use Starter To Turn Crankshaft For 30 Seconds Or Until Oil Pressure Gauge Shows Pressure, Before Engine Is Started
Usage:
All Caterpillar Engines
When an engine is first started, there is a period of time during which the engine runs before oil under pressure is moved through the engine and to the bearings.
During this period, the bearings can wear, and, after many starts, the bearings can become damaged.
The result, in time, can be a bearing failure.
To prevent a bearing failure from the cumulative (added) effects of wear during start-up, use the procedure which follows. Use the starter to turn the crankshaft for 30 seconds or until the oil pressure gauge shows pressure before the governor control lever is moved to start the engine.
