If firing number 4 oil, what are the first two things to check upon losing oil pressure?

When firing number 4 oil, maintaining proper oil pressure is crucial for the efficient functioning of equipment. The first two things to check upon losing oil pressure are to examine the strainer and assess for pump failure.

The strainer is essential because it prevents contaminants from entering the pump and the fuel system. If the strainer becomes clogged, it can restrict the flow of oil, leading to a drop in pressure. Therefore, checking the strainer can help identify if a blockage is causing the pressure issue.

In addition, checking for pump failure is vital because the oil pump is responsible for circulating oil throughout the system. If the pump malfunctions—due to mechanical issues, wear, or other failures—it may not be able to maintain the necessary pressure. Identifying problems with the pump early can prevent damage to the engine or other components serviced by the oil system.

This focus on the strainer and pump is critical for the timely identification and correction of problems that could lead to significant operational issues if not addressed quickly.
