CONTROL GP-TRANSMISSION HYD 4207233 - Caterpillar

Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.Program A
Verification for an Oil Change Interval of 500 Hours
This program consists of three oil change intervals of 500 hours. Oil sampling and analysis is done at 250 hours and 500 hours for each of the three intervals for a total of six oil samples. The analysis includes oil viscosity and infrared (IR) analysis of the oil. If all of the results are satisfactory, the 500 hour oil change interval is acceptable for the machine in that application. Repeat Program A if you change the application of the machine.If a sample does not pass the oil analysis, take one of these actions:
Shorten the oil change interval to 250 hours.
Proceed to Program B.
Change to a preferred oil type in Table 1.Program B
Optimizing Oil Change Intervals
Begin 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 is 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 the Engine Oil and Filter
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
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, NENG2500, "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.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
Refer to Operation and Maintenance Manual, "Access Doors and Covers" for the location of the service points.Park the machine on a level surface and engage the parking brake. Stop the engine.Note: Drain the crankcase while the oil is warm. This 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.

Open crankcase drain valve (1). Allow the oil to drain into a suitable container.
Close crankcase drain valve (1).

Open the front left access door.
Clean the area around engine oil filter (2) before you remove the engine oil filter. Remove the engine oil filter with a strap type wrench. Refer to Operation and Maintenance Manual, "Oil Filter - Inspect".
Clean the filter mounting base with a clean towel. Make sure that all of the old filter seal is removed.
