CASE AS 7R8987 - Caterpillar

Program B
Optimizing Oil Change IntervalsBegin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours. Periodic oil sampling and analysis are done during each interval. The analysis includes oil viscosity and infrared (IR) analysis of the oil. Repeat Program B if you change the application of the machine.If an oil sample does not pass the analysis, shorten the oil change interval, or change to a preferred multigrade oil type in the listing above.Procedure for Changing Engine Oil and Filter
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Note: If the sulfur content in the fuel is greater than 1.5 percent by weight, use an oil that has a TBN of 30 and reduce the oil change interval by one-half.Note: Drain the crankcase while the oil is warm. Warm oil allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining the oil and the particles will recirculate in the engine lubrication system with the new oil.Note: Run the engine at low idle for at least ten minutes before performing any other operations every time the engine oil and oil filter are changed in order to protect your engine. Refer to Operation and Maintenance Manual, "Engine and Machine Warm-Up".

Remove the oil filler plug . Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)". Clean the oil filler plug and install the oil filler plug.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
Start the engine and allow the oil to warm. Check the engine for leaks. Stop the engine.
