(11)Engine Crankcase
Use caution when draining oil or changing filters. Hot oil or components can cause burns if they contact skin.
The engine must be stopped and the oil warm. 1. Remove the crankcase oil drain plug(s) and allow the oil to drain. 2. Wipe the dirt from the oil filter housing. 3. Remove and discard the filter.4. Clean the filter base. Make sure all of old gasket is removed.When installing the new engine oil filter, coat the seal with a light coat of engine oil.5. Install the new filter. Hand tighten the filter an additional 3/4 turn after the gasket contacts the base. 6. Clean the drain plug in clean non-flammable solvent and install it.7. Fill the crankcase. See REFILL CAPACITIES.8. Start and run the engine. Inspect for leaks. Reduce engine speed to low idle. 9. Maintain level to FULL mark on ENGINE RUNNING side of dipstick. Stop the engine.(11A)Engine Valve Lash
Initial valve lash adjustment on new, rebuilt or remanufactured engines is recommended at the first scheduled oil change interval, due to initial wear and seating of valve train components.See topic, "Engine Valve Lash" in "Every 2000 Service Meter Units" for the procedure.(11B)Engine Crankcase Breather
Typical ExampleCheck engine crankcase breather at first oil change interval and clean if necessary.See topic, "Engine Crankcase Breather" in "Every 500 Service Meter Units" for the procedure.(12)Alternator and Fan Drive Belts
1. Check the belts for excessive wear, fraying and cracking.When belt replacement is necessary, belts must be replaced in complete matched sets. Never replace only one belt. The new belt will carry all the load and fail rapidly.2. Apply a 25 pound (110 N) force to the belt, midway between the driving and driven pulley. Measure the belt deflection.Proper belt deflection is 9/16 to 13/16" (14 to 20 mm). Adjust the belt tension as required. To Adjust Alternator Belts:
1. Loosen the locknut on the belt tightener rod. 2. Turn the adjustment nut until correct belt deflection is obtained. 3. Tighten the locknut.4. Check the belt adjustment.To Adjust Fan Drive:
1. Loosen the mounting bolts (A) and adjust with the adjusting bolt (B). 2. When properly adjusted, tighted the mounting bolts (A). 3. Check the belt adjustment.(13)Fan Bearing
Lubricate 1 fitting on fan drive bearing.(14)Cooling System
If Not Equipped With Coolant Conditioner Element
At Operating Temperature, engine coolant is hot and under pressure.Steam can cause personal injury.Check coolant level ONLY when engine is stopped and radiator cap is cool enough to touch with your hand.Remove filler cap slowly to relieve pressure.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
All water is corrosive at engine operating temperature. Use either Caterpillar Cooling System Conditioner liquid, or the coolant conditioner element to treat either plain water or ethylene glycol antifreeze solution. NEVER use both the liquid 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.
1. Loosen radiator cap slowly to relieve pressure, and remove filler cap.It may be necessary,
