CAP-BOTTLE 9W0820 - Caterpillar

Adjust the valve clearance to within 0.08 mm (.003 in) of the valve clearance setting given. Refer to the Service Manual or your Caterpillar dealer for the complete valve adjustment procedure. After setting valve clearances and before installing the valve cover check valve rotators. See next topic.Engine Valve Rotators
Observe Rotation of Valves With Engine Idling After Setting the Valve Clearances
When inspecting the valve rotators, protective glasses or face shield and protective clothing must be worn, to prevent being burned by hot oil spray.
After setting all valve clearances and before installing the valve cover:1. Start the engine.2. Move the governor control to low idle position. 3. Watch the top surface on each valve rotator. Each valve rotator should turn slightly each time the valve closes.If a valve fails to rotate, contact your Caterpillar dealer.Hydraulic System Oil
Change the Oil
At operating temperature, the hydraulic tank is hot and under pressure. Hot oil can cause burns.Remove the fill cap only when the engine is stopped, and the cap is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure.
1. Remove the hydraulic system oil tank filler cap and strainer.2. Wash the filler strainer and filler cap in clean, nonflammable solvent. 3. Remove the oil drain plug, located under the right rear of machine.4. Attach a hose to a 1 inch NPT pipe nipple, 10 cm (4 inch) long.5. Install the pipe nipple and hose into the drain plug opening.6. Turn the pipe nipple clockwise to open the internal drain valve. Allow the oil to drain.7. Remove the pipe nipple. This will close the hydraulic oil tank drain valve.8. Clean and install the drain plug. Tighten the plug to 68 7 N m (50 5 lb ft).9. Change the hydraulic system filter. See "Hydraulic System Filter" in the "Every 500 Service Hours or 3 Months" section.10. Install the filler strainer. 11. Fill the hydraulic system oil tank. See "Refill Capacities."12. Inspect the filler cap gasket. Replace the gasket if damaged.13. Install the oil filler cap.14. Start and run the engine for a few minutes.15. Maintain the oil level to the FULL mark in the sight gauge.16. Stop the engine.Cooling System Coolant
Change the Coolant
At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury.Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.Remove the fill cap slowly to relieve pressure.Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
Coolant should be drained and replaced every 2000 service hours or 1 year. However, when adding liquid Caterpillar cooling system conditioner, or equivalent, every 250 service hours as recommended, the drain period can be extended to 400 service hours or 2 years.Drain the coolant earlier whenever the coolant is dirty or foaming is observed. 1. Loosen the radiator coolant cap slowly to release pressure, and remove the cap.2. Remove the access
