822486 Mercury BRACKET, Guide

Ensure that the engine is stopped before performing this procedure. Attach a DO NOT OPERATE tag to the starting controls.
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 when the cold oil is drained. Drain the crankcase with the oil warm, immediately after the engine is stopped. This method of draining allows the waste particles that are suspended in the oil to be drained.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.

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, "Cat Dealer Service Tool Catalog" or refer to Special Publication, PECJ0003, "Cat Shop Supplies and Tools Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
After the engine has been operated at normal operating temperature, STOP the engine. Note: Drain the oil into a suitable container. Dispose of fluids according to local regulations.
Drain the oil.
If the engine has an oil drain valve, open the valve in order to drain the oil. After the oil has drained, close the valve.
If the engine does not have a drain valve, remove an oil drain plug. Allow the oil to drain. Replace the Oil Filter
Remove the oil filter with a 1U-8760 Chain Wrench.
Cut the oil filter open with a 175-7546 Oil Filter Cutter. 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.Aluminum debris may indicate problems with the bearings of the front gears. If aluminum debris is found, inspect the crankshaft vibration damper and the bearings of the front idler gear.Due to normal wear and friction, small amounts of debris may be found in the oil filter element. If an excessive amount of debris is found in the oil filter element, consult your Cat dealer in order to arrange for further oil analysis.

Typical filter mounting base and filter gasket
Clean the sealing surface of the filter mounting base. Ensure that all of the old oil filter gasket is removed.
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.
Apply clean engine oil to the new oil filter gasket.
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.
Install the oil filter. Tighten the oil filter until the oil filter gasket contacts the base. Tighten the oil filter by hand according to the instructions that are shown on the oil filter. Do not overtighten the oil filter. Fill the Engine Crankcase
Engine damage can occur if the crankcase is filled above the "FULL" mark on the oil level gauge (dipstick).An overfull crankcase can cause the crankshaft to dip into the oil. This will reduce the power that is developed and also force air bubbles into the oil. These bubbles (foam) can cause the following problems: reduction of the oil's ability to lubricate, reduction of oil pressure, inadequate cooling, oil blowing out of the crankcase breathers and excessive oil consumption.Excessive oil consumption will cause deposits to form on the pistons and in the combustion chamber. Deposits in the combustion chamber lead to the following problems: guttering of the valves, packing of carbon under the piston rings and wear of the cylinder liner.If the oil level is above the "FULL" mark on the oil level gauge, drain some of the oil immediately.
Remove the oil filler cap. Fill the crankcase with the proper amount of oil. Refer to the Operation and Maintenance Manual, "Refill Capacities" and Operation and Maintenance Manual, "Fluid Recommendations".
To prevent crankshaft damage or bearing damage, crank the engine with the fuel supply line closed. This will ensure that all of the oil filters are filled with oil before the engine is started. Do not crank the engine for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking again.
Close the fuel supply line. Crank the engine until normal oil pressure shows on the oil pressure gauge. Open the fuel supply line.
Start the engine according to this Operating and Maintenance Manual, "Starting the Engine" procedure. Operate the engine at low idle rpm for 2 minutes to ensure that the lubrication system has oil and that the oil filters are filled. Inspect the engine for oil leaks.
Stop the engine and allow the oil to drain back to the sump for a minimum of 10 minutes.
Remove the oil level gauge and check the
