Engine Valve Lash

Measure Valve Lash (Clearance)

------ WARNING! ------

To prevent possible injury, do not use the starter motor to turn the flywheel.

Hot engine components can cause burns. Allow additional time for the engine to cool before measuring valve clearance.

------WARNING!--------


NOTICE

Measure the valve lash with the engine stopped. To obtain an accurate measurement, allow at least 20 minutes for the valves to cool the engine cylinder head and block temperature.


If the valve clearance is within ± 0.08 mm (.003 in) of the nominal clearance given, adjustment is not required. If the clearance is not within these limits, set the clearance as given in the chart.

Refer to the Service Manual or your AVSpare dealer for the complete valve adjustment procedure.

Cooling System

Change the Coolant

------ WARNING! ------

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.

------WARNING!--------


NOTICE

All water is corrosive at engine operating temperatures. Use AVSpare coolant conditioner to treat either plain water or ethylene glycol solution.

Do not use AVSpare coolant conditioner with Dowtherm 209 Full-Fill coolant. Follow recommendations provided with Dowtherm 209 Full-Fill coolant.

If the machine is to be shipped to, or stored in, an area with temperatures below 0°C (32°F), the cooling system must be protected to the lowest expected outside temperature.

Clean the cooling system if it is contaminated, if engine overheats or if foaming is observed in the radiator.


1. Open the radiator cap access door. Remove the cap slowly to relieve pressure.

2. Open the drain valve and allow the coolant to drain. Drain valve located under the machine radiator.
3. Close the drain valve. Fill the system with cleaning solution. Use a commercially available cleaner or 1 kg (2 lb) sodium bisulfate per 38 liters (10 gal) of water as a cleaner.
4. Start and operate the engine for 1/2hour. Stop the engine and drain the cleaning solution.
5. Flush the system, with the engine stopped, with water until the draining water is clear.
6. Close the drain valve. Fill the system with a neutralizer. Use a commercially available neutralizer or 250 grams (1/2lb) sodium carbonate crystals per 38 liters (10 gal) of water.
7. Operate the engine for 10 minutes. Stop the engine and drain the neutralizer.
8. Flush the system, with the engine stopped, until the draining water is clear. Close the drain valve.
9. Fill the system with clean water and operate the engine for five minutes. Stop the engine and drain the water.
10. Repeat step 9 several times, if necessary, until the drained water is clear.
11. Mix antifreeze coolant solution to provide protection to the lowest expected outside temperature.
12. Add .9 liter (1 qt) of AVSpare cooling system conditioner, or equivalent, to the coolant.
13. To avoid air locks, add coolant slowly at 19 liters (5 U.S. gal) per minute or less. See "Refill Capacities."
14. With the radiator cap off, start and operate the engine. When the coolant level stabilizes, add coolant, if necessary, to within 1 cm (1/2 inch) of the bottom of the fill pipe.
15. Replace the cap if the gasket is damaged. Install the cap.

Close the access door.

Pump Drive

Change Oil

------ WARNING! ------

Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

------WARNING!--------


NOTICE

Overfilling can cause overheating of the pump drive.


1. Open the right side rear access door.

2. Remove the pump drive drain plug. Allow the oil to drain. Clean and install the drain plug.

3. Open the right rear access door. Remove the oil fill plug.

4. Remove the oil level plug.
5. Fill the compartment to the bottom of the level plug opening. See "Refill Capacities."
6. Clean and install the oil level and oil fill plugs.
7. Remove the pump drive case breather. Wash in solvent, dry and install.
8. Close the access doors.

Hydraulic System

Change Oil and Wash Filler Strainer

------ WARNING! ------

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.

------WARNING!--------


NOTICE

An improper hydraulic oil level can result in machine damage.


1. Open the right side front access door.

2. Remove the hydraulic tank fill cap slowly to relieve pressure in the tank.

3. The hydraulic tank oil drain valve is located on the right side of the machine under the upper structure.

4. Remove the oil drain valve plug.
5. Install a pipe and hose to open drain valve. Drain into a container.
6. Change the hydraulic oil filter elements. See "Hydraulic System" at "Every 500 Service Hours or 3 Months."
7. Remove the pipe to close the drain valve. Clean and install the plug.
8. Inspect the hydraulic suction hoses and clamps. Replace hoses that are swollen or cracked. Tighten all hose clamps to 11 N·m (100 lb in).

9. Remove the spring lockring with pliers.
10. Remove the hydraulic tank oil fill strainer.

Wash the strainer in clean, nonflammable solvent and dry. Install the strainer and lockring.

11. Fill the hydraulic tank with oil. See "Refill Capacities." Replace the cap seal if it is damaged. Clean and install the cap.
12. Start the engine and operate it at LOW IDLE to fill the filters. Check for leaks. Cycle all hydraulic equipment.
13. With the machine level, position the equipment as shown.

If backhoe equipped, position the bucket flat on the ground with the stick cylinder fully extended.

If clamshell equipped, position the bucket open on the ground with the stick cylinder fully extended.

14. Stop the engine. Check the hydraulic oil level.

15. Maintain the oil level between the ADD and FULL marks on the sight gauge.
16. Close and secure the access door.
