Kubota Diesel Engine V1305

Change of radiator coolant (L.L.C.)

1. To drain coolant, always open both drain cocks and simultaneously open the radiator cap as well. With the radiator cap kept closed, a complete drain of water is impossible.

2. Remove the overflow pipe of the radiator pressure cap to drain the recovery tank.

3. Prescribed coolant volume (U.S.gallons)

Quantity - 4.0L (1.06 U.S.gals.)

NOTE! Coolant quantities shown are for standard radiators. 4. An improperly tightened radiator cap or a gap between the cap and the seat quickens loss of coolant.

5. Check and clean the plug threads and surface and the pucking thims of the water drain plug to prevent dirt and debris from the entering the engine.

6. Coolant (Radiator cleaner and anti-freeze); All Seasons: Pure water and anti-freeze (See "Anti-freeze" in "RADIATOR" section.)

Remedies for quick decrease of coolant 1. Check any dust and dirt between the radiator fins and tube. If any, remove them from the fins and the tube.

WARNING! To avoid personal injury or death: Be careful not to let the battery electrolyte contact your body or clothing. Wear eye protection and rubber gloves, since the diluted sulfuric acid solution burns skin and eats holes in clothing.

DANGER! Do not use or charge the battery if its fluid level stands below the LOWER (lower limit level) mark. Otherwise, the battery component parts may deteriorate earlier than expected, which may shorten the battery's service life or cause an explosion.

WARNING! To avoid personal injury or death: When the battery is being activated, hydrogen and oxygen gases in the battery are extremely explosive. Keep open sparks and flames away from the battery at all times, especially when charging the battery.

Is the electrolyte level to the bottom of vent wells?

Is the battery fluid level between the UPPER and LOWER levels?

Is the battery being charged in a well-ventilated place?

Is the charger positive terminal connected to the battery positive terminal, and negative to the negative?

Is the battery being recharged as early as possible?

Is the battery of equal specification shown in 'SPECIFICATIONS' section when exchanging an old battery into new one?

WARNING! To avoid personal injury or death: Check or replace the fuel pipes after stopping the engine. Broken fuel pipes can cause fires.

If the clamp band is loose, apply oil to the screw of the band, and tighten the band securely.

Are the fuel pipes, made of rubber, worn out?

If the fuel pipes, made of rubber, become worn out, replace them and clamp bands every 2 years.

Are the fuel pipes and clamp bands found worn or damaged before 2 years' pass?

If the fuel pipes and clamp bands are found worn or damaged before 2 years' pass, replace or repair them at once.

After replacement of the pipes and bands, air-bleed the fuel system.

Important: When the fuel pipes are not installed, plug them at both ends with clean cloth or paper to prevent dirt from entering. Dirt in the pipes can cause fuel injection pump malfunction.

Warning: This procedure requires trained personnel with PPE!

Fuel filter cartridge replaced with a new one

Fuel oil applied thinly over the gasket

Cartridge tightened into position by hand-tightening only

IMPORTANT! Replace the fuel filter cartridge periodically to prevent wear of the fuel injection pump plunger or the injection nozzle, due to dirt in the fuel.

NOTE! The fuel filter cartridge and water separator should be replaced more earlier according to the fuel classification in use.

WARNING! To avoid personal injury or death: Be sure to stop the engine before checking and changing the engine oil and the oil filter cartridge.

Do not touch muffler or exhaust pipes while they are hot; Severe burns could result.

Always stop the engine and allow it to cool before conducting inspections, maintenance, or for a cleaning procedure.

Contact with engine oil can damage your skin. Put on gloves when using engine oil. If you come in contact with engine oil, wash it off immediately.

NOTE! Be sure to inspect the engine, locating it on a horizontal place. If placed on gradients accurately, oil quantity may not be measured.

Be sure to keep the oil level between upper and lower limits of the oil gauge. Too much oil may cause a drop in output or excessive blow-by gas.

On the closed breather type engine in which mist is sucked through port, too much oil may cause oil hammer.

While too little oil, may seize the engine's rotating and sliding parts. (The closed breather is an option.)

Check the engine oil level before starting or more than 5 minutes after stopping the engine.
