TUBE AS 2459868 - Caterpillar

Do not operate the engine with low oil pressure.
Engine damage will result. If measured oil pressure is low, discontinue engine operation until the problem is corrected.
Use this procedure in order to troubleshoot low engine oil pressure or use this procedure if one of the following event codes is active. Refer to Troubleshooting, "Event Code List" for information about event codes and the default trip points for these codes.
Table 1
Event Code    
Code and Description     Default Conditions which Generate this Code     System Response    
E360(1) Low Engine Oil Pressure     The engine oil pressure is below a map dependent value.     If equipped, the warning light will illuminate.
The code is logged.    
E360(3) Low Engine Oil Pressure     The engine oil pressure is below a map dependent value.     If equipped, the warning light will illuminate.
The code is logged.
If the engine is not shutdown the operator must immediately perform a safe shutdown.    Probable Causes
Engine oil
Engine oil pressure gauge
Engine oil filter
Engine oil cooler
Piston cooling jets
Engine oil suction tube
Engine oil pump
Engine wearRecommended Actions
Engine Oil
Inspect the engine oil level. If necessary, add oil.Note: Make sure that engine oil of the correct specification is used. If necessary, drain the oil system and refill the oil system with engine oil of the correct specification. Refer to the maintenance section Operation and Maintenance Manual.Engine Oil Pressure Gauge
Check the actual engine oil pressure with a calibrated test gauge. Compare the oil pressure reading from Caterpillar Electronic Technician (ET) to the pressure on the test gauge.Engine Oil Filter
Remove the engine oil filter. Inspect the engine oil filter for evidence of blockage and/or contamination. If necessary, install a new engine oil filter. Refer to the maintenance section Operation and Maintenance Manual.Engine Oil Cooler
If oil flow or coolant flow through the oil cooler is suspected of being low, replace the oil cooler. Refer to Disassembly and Assembly.Piston Cooling Jets
Inspect the piston cooling jets for damage. If necessary, replace any piston cooling jet(s). Refer to Disassembly and Assembly.Engine Oil Suction Tube
Check the inlet screen on the oil suction tube and remove any material that may be restricting oil flow.
Check the joints of the oil suction tube for cracks or a damaged joint that may allow air leakage into the supply to the oil pump.Engine Oil Pump
Inspect the components of the engine oil pump for excessive wear. If necessary, repair the oil pump or replace the oil pump. Refer to Disassembly and Assembly.Engine Wear
Inspect the camshaft and camshaft bearings for excessive wear. Inspect the crankshaft and crankshaft bearings. Inspect the connecting rod bearings and inspect the idler gear bearing. Excessive wear to discrete components may be an indication of a blocked oil passage. Determine if the excessive wear is from low system pressure or from passages that are blocked.
