Turbochargers
Inspect/Check
If service is required, contact your Caterpillar dealer for turbocharger service options.1. Remove the exhaust outlet piping and inlet piping from the turbocharger.2. Turn the turbine and compressor wheel by hand.3. The assembly should turn freely. It should be difficult to detect movement of the shaft in the bearing. If the shaft is loose in the bearings, an inspection of the internal components should be made.4. Inspect the turbine wheel and compressor wheel for contact with the turbocharger housing.5. There should not be any visible signs of contact between the turbine wheel or compressor wheel and the turbocharger housing.6. Visually check for oil leaks.7. Repeat the above procedure for the other turbocharger.Overhaul
The Maintenance Management Schedule gives Caterpillar's recommendation for performing an overhaul. The interval is expressed in total amount of fuel consumed as well as Service Hours, WHICHEVER OCCURS FIRST. The best figure to use is total fuel consumed, even if this figure is estimated. Fuel consumption more closely follows the load upon the engine.The hours figure is an average value for a reasonable load factor. The hours figure will be too high if the engine is run at high load and too low if the engine is lightly loaded.Use the fuel consumption or service hour figure only as a guideline. Other factors, such as how conscientiously preventive maintenance has been performed, fuel quality, operating conditions, S O S results, etc., are important in deciding when to perform an overhaul, as well as some important economic points to keep in mind.All 3516 High Output marine engines should be scheduled for Overhaul using the following schedule: Caterpillar has chosen the recommended overhaul periods with total operating costs in mind.As an example, consider the following graph. 1. The solid line shows the maintenance and repair costs for an owner who followed the maintenance and repair recommendations for inspection, repair or exchange for components and for overhauls. The peaks represent the years in which top-end overhauls and full overhauls occurred.2. The dotted line represents another user operating identically except he has chosen to operate beyond the Caterpillar recommended intervals. His peaks also represent years with top-end and full overhauls.Notice that in the early years, the "repair-after-failure" philosophy is a little less expensive. Also notice that the first top-end overhaul and overhaul were each delayed one year. But notice also that the peaks for this graph are significantly higher than the peaks for the customer using the "repair-before-failure" philosophy.The higher peaks result from two key factors. First, waiting until a component fails or wears out means more likelihood of an expensive failure, requiring more parts, labor and cleanup. Second, excessive wear means less components will be reusable, or at least will need more labor to salvage or repair.In this example, extending overhaul periods 2000 hours resulted in total maintenance and repair costs increasing by almost 30%. There is very little reasoning which can justify running the engine beyond recommended maintenance and overhaul intervals.Note that the 30% increase does not consider the cost of any additional downtime that resulted from the additional time to repair the worn out engine. Or, the additional revenue lost during the repair period.The choice to continue running, or to overhaul the engine at the recommended service interval is yours. Maybe there won't be a failure within a reasonable amount of time, but more parts will require replacement and you will have to do the overhaul sooner or later anyway. Why drive up your repair costs unnecessarily, and why risk your luck with a potential equipment failure? The longer you wait, the greater your risks, your costs, and your downtime.Most users will save money by overhauling at the intervals recommended in the charts. It is virtually NEVER CHEAPER to wait for the engine to show signs of excessive wear or failure. "REPAIR-BEFORE-FAILURE" is the least expensive alternative for most components and engines, when all costs are accounted for.Overhaul Programs
Caterpillar recommends that an In-Hull Overhaul be performed at this service interval. Contact your Caterpillar dealer for information.Overhaul Before Failure (In-Hull Overhaul)
A planned in-hull overhaul 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 breakdown had you continued to operate to failure* Get the best cost/value relationship per hour of extended lifeFlat Rate Overhaul
To further control your in-hull overhaul costs, Caterpillar recommends that you contact your dealer for information regarding the availability of a Flat Rate (Firm Price) Overhaul.A Flat Rate (Firm Price) Overhaul is not really a type of overhaul but a program that guarantees the maximum price you will pay for an in-hull overhaul.Flat Rate Overhauls will help you control your costs.Flat rate prices on preventive maintenance programs or major repair options are available from many servicing dealers for Caterpillar Marine Engine models.Overhaul Options
Caterpillar Dealer - Contact your Caterpillar dealer to schedule a before failure overhaul. Overhaul Kit - Some dealers have developed kits for those users that prefer to perform their own overhaul. This kit includes a combination of new, reused and Remanufactured parts. Also included is a step-by-step instruction regarding how to perform an in-frame overhaul. An Overhaul Kit simplifies parts ordering, helps speed repairs and reduces parts costs. Contact your local Caterpillar dealer for information regarding the availability of Overhaul Kits.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.Overhaul-General
If you elect to perform an in-hull overhaul yourself, without having a Caterpillar dealer perform the overhaul for you or without using an overhaul kit, then you should be aware of the following:Service
