94916 Mercruiser WEAR PLATE, OUTER

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.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Oil and Filter Change Intervals
The standard engine oil and filter change period is 500 hours. There are several other factors that can alter the standard engine oil and filter change of 500 hours.
If the engine is using engine oil analysis to determine oil and filter change period.
The engine is working in a severe service environment/Load Factor
Infrequent operation of the engineRefer to this "Operation and Maintenance Manual", Severe Service Application, for more information on reducing the engine oil and filter change period. For severe service applications the recommended oil and filter change period is 250 hours.If the engine is operated in severe service conditions, Caterpillar recommends the use of engine oil sampling. Refer to this "Operation and Maintenance Manual", Engine Oil sample - Obtain, for more information. If the engine is operated infrequently less than 500 hours in a 12-month period, then the engine oil and filter change should be conducted yearly.Drain the Engine Oil
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with the draining cold oil. Drain the crankcase with the engine stopped. Drain the crankcase with the oil warm. This draining method allows the waste particles that are suspended in the oil to be drained correctly.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.After the engine has been run at the normal operating temperature, stop the engine and ensure that the engine cannot start. Use one of the following methods to drain the engine crankcase oil:
If the engine is equipped with a drain valve, turn the drain valve knob counterclockwise to drain the oil. After the oil has drained, turn the drain valve knob clockwise to close the drain valve.
If the engine is not equipped with a drain valve, remove the oil drain plug to allow the oil to drain. After the oil has drained, the oil drain plug should be cleaned and installed.Replace the Oil Filter
Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.

Typical example
Remove the oil filter (2) with a 1U-8760 Chain Wrench.Note: The following actions can be carried out as part of the preventive maintenance program.
Cut the oil filter open with a 175-7546 Oil Filter Cutter Gp. Break apart the pleats and inspect the oil filter for metal debris. An excessive amount of metal debris in the oil filter may indicate early wear or a pending failure.Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the oil filter element. Ferrous metals may indicate wear on the steel and cast iron parts of the engine.Nonferrous metals may indicate wear on the aluminum parts, brass parts, or bronze parts of the engine. Parts that may be affected include the following items: main bearings, rod bearings, turbocharger bearings, and cylinder heads.Due to normal wear and friction finding small amounts of debris in the oil filter is not uncommon. Consult your Cat dealer to arrange for a further analysis if an excessive amount of debris is found in the oil filter.
Clean the sealing surface of the cylinder block (1).
Apply clean engine oil to the O ring seal (3).
Do not fill the oil filters with oil before installing them. This oil would not be filtered and could be contaminated. Contaminated oil can cause accelerated wear to engine components or engine damage.
Install the new oil filter (2), spin on the oil filter until the O ring seal (3) contacts the oil filter base. Rotate the oil filter ¾ of a full turn.Fill the Engine Crankcase
Remove the oil filler cap. Refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" for more information on lubricant specifications. Fill the crankcase with the correct amount of oil. Refer to this Operation and Maintenance Manual, "Refill Capacities" for more information on refill capacities.
If equipped with an auxiliary oil filter system or a remote oil filter system, follow the OEM or filter manufacturer's recommendations. Under filling or overfilling the crankcase with oil can cause engine damage.
To prevent crankshaft bearing damage, crank the engine with the fuel OFF. This will fill the oil filters before starting the engine. Do not crank the engine for more than 30 seconds.
Start the engine and run the engine at "LOW IDLE" for 2 minutes. Perform this procedure to ensure that the lubrication system has oil and that the oil filters are filled. Inspect the oil filter for oil leaks.
Stop the engine and allow the oil to drain back to the sump for a minimum of 10 minutes.
