Estimating Oil Consumption
Oil consumption, fuel consumption, and maintenance information can be used to estimate the total operating cost for your Caterpillar engine. Oil consumption can also be used to estimate the capacity of a makeup oil system required to accomodate your maintenance intervals.Oil consumption is proportional to the engine operating percent load. The higher the percent load, the higher the amount of oil consumed per hour.The oil consumption rate, or brake specific oil consumption (BSOC) is measured in grams/brake kW-hour (lb/bhp-hour). The BSOC varies depending on the load on your engine. Contact your Caterpillar dealer for assistance in determining typical oil consumption for your engine.Oil Consumption as an Overhaul Indicator
When an engine's oil consumption has risen to three times the initial (new) consumption rate due to normal wear, then the engine should be scheduled for overhaul. There may be a corresponding increase in blowby and a slight increase in fuel consumption.Overhaul Before Failure
A planned Overhaul Before Failure may be your best value, because you can:* Avoid costly unplanned downtime.* Reuse as many original parts as standards permit.* Extend your engine's service life without the risk of a major catastrophe had you continued to operate to failure.* Get the best cost/value relationship per hour of extended life.After Failure Overhaul
If you experience a major engine failure which requires removal of the engine from the hull, there are also many After Failure Overhaul options available. An overhaul should be performed if your block or crankshaft needs to be repaired.If the block and/or crankshaft is repairable, overhaul cost should be between 40 and 50 percent of the cost of a new engine (with like exchange core).This lower cost can be attributed to Caterpillar "designed-in" features, and Cat dealer and Caterpillar Remanufactured exchange components.Overhaul Recommendation
To minimize downtime and provide you with the lowest cost and highest value, Caterpillar recommends that the engine be overhauled before failure by scheduling an overhaul with your Caterpillar dealer. Overhaul programs vary with engine application and from dealer to dealer. Therefore, Caterpillar recommends that you confer with your dealer to obtain specific information regarding the types of programs offered and overhaul services provided for extending the life of your engine.If you elect to perform an overhaul without Caterpillar dealer overhaul service, you should be aware of the maintenance that follows.Unit Fuel Injector
Clean the fuel injector body and replace the O-rings. Replace the O-rings and gasket on the injector sleeve. Clean the injector seat area in injector sleeve. Refer to the Service Manual for the complete procedure, or consult with your Caterpillar dealer for assistance.Crankshaft, Camshaft, and Cam Bearings, Crankshaft Vibration Damper.
Inspect
The ideal time for inspecting these items is while your engine is disassembled for overhaul. Inspect each component for potential damage as follows.* Crankshaft-Inspect for deflection, journal damage, and bearing material seized to the journal. At the same time, check the taper and profile of the crankshaft journals by interpreting your main and rod bearing wear patterns. If the crankshaft is removed for any reason, use the magnetic
