The engine oil pressure may be checked electronically by using the Cat® Electronic Technician (ET). The engine oil pressure can be measured with Cat ET. Refer to Troubleshooting for information on the use of the Cat ET.Reasons for Low Engine Oil Pressure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Engine oil level is low. Refer to "Engine Oil Level" in Troubleshooting, "Oil Pressure Is Low".
Engine oil is contaminated. Refer to Step 1.
The engine oil bypass valves are open. Refer to "Oil Filter Bypass" in Troubleshooting, "Oil Pressure Is Low".
The engine lubrication system is open. Refer to Step 2.
The oil pickup tube has a leak or a restricted inlet screen. Refer to Step 3.
The engine oil pump is faulty. Refer to Step 4 and to "Oil Pump" in Troubleshooting, "Oil Pressure Is Low".
Engine bearings have excessive clearance. Refer to "Worn Engine Components" in Troubleshooting, "Oil Pressure Is Low".
Engine oil that is contaminated with fuel or coolant will cause low engine oil pressure. High engine oil level in the crankcase can be an indication of contamination. Determine the reason for contamination of the engine oil and make the necessary repairs. Replace the engine oil with the approved grade of engine oil. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
An oil line or an oil passage that is open, broken, or disconnected will cause low engine oil pressure. An open lubrication system could be caused by a piston cooling jet that is missing or damaged. Determine the reason for an open lubrication system of the engine and make the necessary repairs.Note: The piston cooling jets direct engine oil toward the bottom of the piston to cool the piston. The piston cooling jets also provide lubrication for the piston pin. Breakage, a restriction, or an incorrect installation of the piston cooling jets will cause seizure of the piston.
The inlet screen of the oil pickup tube for the engine oil pump can have a restriction. This restriction will cause cavitation and a loss of engine oil pressure. Check the inlet screen on the oil pickup tube and remove any material that may be restricting engine oil flow. Low engine oil pressure may also be the result of the oil pickup tube that is drawing in air. Check the joints of the oil pickup tube for cracks or a damaged O-ring seal. Remove the engine oil pan to gain access to the oil pickup tube and the oil screen. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install" for more information.
Check the following problems that may occur to the engine oil pump.
Air leakage in the supply side of the oil pump will also cause cavitation and loss of oil pressure. Check the supply side of the oil pump and make necessary repairs. For information on the repair of the engine oil pump, refer to Disassembly and Assembly, "Engine Oil Pump - Remove".
Oil pump gears that have too much wear will cause a reduction in oil pressure. Repair the engine oil pump. For information on the repair of the engine oil pump, refer to Disassembly and Assembly, "Engine Oil Pump - Remove".Reason for High Engine Oil Pressure

Engine oil pressure will be high if the engine oil bypass valves become stuck in the closed position and the engine oil flow is restricted. Foreign matter in the engine oil system could cause a restriction of the oil flow and the movement of the engine oil bypass valves. If the engine oil bypass valves are stuck in the closed position, replace the oil filter base. Install new engine oil filters. New engine oil filters will prevent more debris from causing this problem.
