Inspect/Rebuild or Exchange
One unscheduled failure caused by any of these components will cost more in downtime than maintaining them before failure. The cost incurred to maintain these components before failure as recommended, could be significantly less than if the component fails.It is less costly to maintain components before failure than it is to operate the engine until the component fails.By maintaining these components before failure, unscheduled downtime will be minimized and the chances for potential damage to other engine parts reduced. The prevention of unscheduled downtime saves money and lowers operating costs.If the engine is operated until the component(s) fails, it could cause additional damage to the engine resulting in repair costs as much as twenty-five times or more the repair cost before failure cost. This excessive cost is due to the additional engine damage that could have been prevented.Our recommended intervals for performing preventive maintenance on these components are based on experience and gathered data relative to the expectant life of the engine and its components. These maintenance intervals were developed as a service for the owner's use to minimize unexpected and costly repairs as well as to serve as an aid to lowering operating costs.Failure to follow the recommendations could result in unexpected, costly repairs and unscheduled downtime.Caterpillar recommends that the most cost effective method of operation for these components is to inspect the unit before it fails.Electric Starting Motor - Removal and Installation
