Fuel System Air Removal

AIR MUST BE REMOVED FROM THE FUEL SYSTEM. AIR CAN ENTER THE FUEL SYSTEM WHEN:

1. The engine stopped caused from lack of fuel.

2. The fuel filter has been replaced or the filter cup has been cleaned.

3. Any connections between the injection pump and fuel tank have been loosened or disconnected for any reasons.

4. The tractor has not been operated for long time.

5. The fuel pump has not operated correctly.

NOTE: This tractor has the function which discharges the air included in the fuel system automatically. The air exhaust procedure is as follows.

Step 1

The starter switch is turned to the position of [ ]. Air will be discharged if it holds in the position as it is for 30 seconds.

Fuel Injection Pump and Nozzle Check

NOTE:Figure of the engine Unit

The fuel injection pump and nozzles are precision units and must be serviced only by your dealer.

The injection pump is correctly set and sealed at the factory and should not require an adjustment. Whenever adjustment or repairs are necessary, see your dealer. Do not tamper with any of the pump units.

Hydraulic oil or diesel fuel leaking under pressure can penetrate the skin and cause injection or other injury.

To Prevent Personal Injury:

Relieve all pressure, before disconnecting fluid lines. Before applying pressure, make sure all connections are tight and components are in good condition. Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately.

Air Induction System

The air induction system components require service at different intervals according to local operating conditions.

Service Specifications

Dump Valve…………………………………………………………… Clean daily or every 10 hours

Filter Element

Clean Element………………………………………………………………………. When necessary

Replace Element…………………………...........After 10 cleanings or When necessary or yearly System Inspection………………….......………... Every 200 hours or yearly whichever occurs first

Your tractor is equipped with a dry-type air cleaner with a replaceable element.

IMPORTANT: Service the air induction system at the given service intervals. Correct maintenance will make longer life of the engine. Keep all connections on the outlet hose tight.

Dump Valve

The dust in the filter case should be dumped daily by using the dump valve when operating in extremely dusty conditions.

Air Filter Element Removal

Avoid over servicing the air filter element. The filter element should be removed for cleaning only when restriction causes a power loss.

When servicing the air filter element, loosen the wing bolt and remove element by pulling it straight out very carefully. Clean interior of canister.

After replacing the new or cleaned element, install and tighten the wing bolt.

NOTE: Never attempt to remove the element from the air cleaner while the engine is running.

When installing the element, inspect the element gasket. If the gasket or element surface is damaged, replace the element immediately.

Element Cleaning

Use clean, dry compressed air up and down the pleats on the clean side (inside) of the element.

Continue this until the element is clean.

NOTE:

1. The paper element must be handled with care. Do not hit the element against a hard surface.

2. Air pressure at the nozzle must not exceed 689 kPa (100 psi).

3. It may be necessary to replace the element sooner if the time interval between servicing becomes short indicating the element dose not respond to cleaning (soot contaminated).

System Inspection

Check the dump valve and the all hoses for cracks and wear. Replace if needed. All the connections on the hoses must be tight. All the gaskets must be in good condition and the bolts must be drawn up tight.

NOTE:Inspect the hoses and connections after the first 50 hours of operation and replace when necessary.
