Engine Oil
Change Oil and Filters
With the oil warm and the engine stopped, drain the crankcase. 1. Remove the crankcase drain plug.2. Open the crankcase drain valve and drain the oil.3. Use a strap wrench to remove the oil filters. Make certain all of the old seal is removed from the filter base.4. Clean the filter base.5. Coat the seal with engine oil.6. Install the new filter by hand. When the seal contacts the base, tighten 3/4 turn more.
Do not overtighten the filter.
7. Install the crankcase drain plug.8. Close the crankcase drain valve.9. If a prelube pump is available, fill the oil filter housing and the oil cooler with oil. 10. If prelube pump is not available, then proceed with filling the crankcase. See "Lubricant Viscosities and Refill Capacities" and "Lubricant Specifications."11. Remove the oil fill plug to add oil.12. Crank the engine with the fuel supply line closed until 70 kPa (10 psi) oil pressure shows on the gauge. Open the fuel supply line valve. Start and run the engine. Inspect for leaks. Reduce engine speed to low idle. 13. Maintain oil level to the FULL mark on the ENGINE RUNNING side of the dipstick. Stop the engine.Cooling System
Add Coolant Conditioner
All water is corrosive at engine operating temperature. Use either Caterpillar Cooling System Conditioner, or Coolant Conditioner Element to treat either plain water or ethylene glycol antifreeze solution. Never use both the cooling system conditioner and the coolant conditioner element at the same time.Do not use Caterpillar Cooling System Conditioner or Coolant Conditioner Elements with Dowtherm 209 Full-Fill coolant. Follow recommendations provided with Dowtherm 209 Full-Fill coolant. Refer to "Cooling System Specifications" section of this manual before adding conditioner.
Add 1.0 liter (1 quart) of Caterpillar Cooling System Conditioner for each 152 liters (40 U.S. gallons) of coolant capacity. This will maintain the required 3% to 6% concentration of conditioner.
Typical Example1. Remove radiator filler cap slowly to relieve pressure.It may be necessary to drain enough coolant to allow for the addition of cooling system conditioner.2. Add Caterpillar Cooling System Conditioner.3. Inspect radiator filler cap gasket. Replace cap if damaged.4. Install radiator filler cap.Fuel Filters
Change Filters
See "Fuel System" under "When Required" for procedure to change fuel filters.Batteries
Check Electrolyte Level
According to your battery type, check the electrolyte level using the chart below. Tighten the battery retainers every 1000 hours on all batteries. 1. Remove the fill caps. Maintain electrolyte to bottom of fill plug openings.If addition of water is necessary, use distilled water. If distilled water is not available use clean water that is low in minerals. Do not use artificially softened water.At proper charging rate, batteries should not require more than 30 cc (1 ounce) water per cell per week.Keep batteries clean.Cleaning Batteries
1. Loosen and remove cable clamps from all battery terminals.2. Clean all battery terminals.3. Clean all cable clamps.4. Install and tighten cable clamps to battery terminals.5. Coat cable clamps and terminals with grease.Belts
Inspect Belts
1. Remove the belt guard. 2. Inspect the belts for wear. Replace belts if worn, cracked or frayed.When belt replacement is necessary, belts must be replaced in complete matched sets. Never replace only one belt. The new belt will carry all of the load and consequently, fail rapidly.3. If belts do not require replacement or adjustment, install the belt guard. If belts require adjustment or replacement, do not install the belt guard. See "Adjust Belts" when belt adjustment and/or replacement is necessary.Adjust Belts
To Adjust Alternator Belts
1. Apply a 110 N (25 lb) force perpendicular to the belt, midway between the driving and driven pulley. Measure the belt deflection. Proper belt deflection is 15 to 20 mm (5/8 to 3/4 inch). Adjust the belt tension as required.2. Loosen locknut (1) on the belt tightener rod.3. Turn adjustment nut (2) until correct belt deflection is obtained.4. Tighten locknut (1).5. Check the belt adjustment.6. Install the belt guard.To Adjust Fan Drive Belts
1. Loosen six bolts (1) holding the fan mounting plate to the engine.2. Loosen locknut (2). Turn adjusting screw (3) until the belts are properly adjusted.3. Tighten six bolts (1) and locknut (2).4. Check the belt adjustment. If adjustment is not correct, repeat steps 1 through 3.Fan Drive Bearing and/or Belt Tightener Group
Fan Drive Bearing
Some fan drive groups have a pressure relief fitting (1) and a grease fitting (2). Do not replace the pressure relief fitting with a grease fitting. A failure can result.
Lubricate fan drive bearing grease fitting (2).Belt Tightener Bearing
Some belt tightener groups have a pressure relief fitting (1) and a grease fitting (2). Do not replace the pressure relief fitting with a grease fitting. A failure can result.
Lubricate belt tightener grease fitting (2).
