GASKET 2G9793 - Caterpillar

Note: Severe slopes can cause low oil pressure. The oil level in the engine crankcase must be at the "FULL" mark on the dipstick. Refer to Operation and Maintenance Manual for details.Use this procedure in order to troubleshoot low engine oil pressure. Use this procedure if one of the following event codes is active. Access the engine monitoring system on Caterpillar Electronic Technician (ET) in order to view the current trip points for these codes. Refer to Troubleshooting, "Engine Monitoring Parameters" for information about engine events.

Engine Oil Level
Check the engine oil level in the crankcase. Refer to the Operation and Maintenance Manual for calibration of the dipstick gauge. The oil level can possibly be too far below the oil pump supply tube. There will not be enough oil and the oil pump will not supply enough lubrication to the engine components.
If the engine oil level is low, add engine oil in order to obtain the correct level. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
If the problem has been corrected, return the unit to service.
