Procedure
- 4. CHECK AND MAINTENANCE
- [1]
- DAILY CHECK POINTS
- Checking Engine Oil Level
- 1. Level the engine.
- 2. To check the oil level, draw out the dipstick (1), wipe it clean,
- reinsert it, and draw it out again.
- Check to see that the oil level lies between the two notches.
- 3. If the level is too low, add new oil to the specified level.
- IMPORTANT
- Q
- • When using an oil of different maker or viscosity from the
- previous, drain old oil. Never mix two different types of oil.
- NOTE
- Q
- • 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 dipstick. 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
- caused oil hammer. While too little oil, may seize the
- engine’s rotating and sliding parts.

- Checking and Replenish Coolant
- 1. Without recovery tank :
- Remove the radiator cap (1) and check to see that the coolant
- level is just below the port.
- With recovery tank (2) :
- Check to see that the coolant level lies between FULL (A) and
- LOW (B).
- 2. If coolant level is too low, check the reason for decreasing
- coolant.
- (Case 1)
- If coolant is decreasing by evaporation, replenish only fresh, soft
- water.
- (Case 2)
- If coolant is decreasing by leak, replenish coolant of the same
- manufacture and type in the specified mixture ratio (fresh, soft
- water and L.L.C.). If the coolant brand cannot be identified, drain
- out all of the remaining coolant and refill with a totally new brand
- of coolant mix.
- CAUTION
- • Do not remove the radiator cap until coolant temperature is
- below its boiling point. Then loosen the cap slightly to
- relieve any excess pressure before removing the cap
- completely.
- IMPORTANT
- Q
- • During filling the coolant, air must be vented from the engine
- coolant passages. The air vents by jiggling the radiator
- upper and lower hoses.
- • Be sure to close the radiator cap securely. If the cap is loose
- or improperly closed, coolant may leak out and the engine
- could overheat.
- • Do not use an antifreeze and scale inhibitor at the same time.
- • Never mix the different type or brand of L.L.C..

- Changing Engine Oil
- CAUTION
- • Be sure to stop engine before changing engine oil.
- 1. Start and warm up the engine for approx. 5 minutes.
- 2. Place an oil pan underneath the engine.
- 3. To drain the used oil, remove the drain plug (1) at the bottom of
- the engine and drain the oil completely.
- 4. Screw the drain plug (1).
- 5. Fill new oil up to upper line on the dipstick (2).
- IMPORTANT
- Q
- • When using an oil of different maker or viscosity from the
- previous one, remove all of the old oil.
- • Never mix two different types of oil.
- • Engine oil should have properties of API classification CD/
- CE/CF/CF-4/CG-4.
- • Use the proper SAE Engine Oil according to ambient
- temperature.

- Replacing Oil Filter Cartridge
- CAUTION
- • Be sure to stop the engine before replacing filter cartridge.
- 1. Remove the oil filter cartridge (1) with the filter wrench.
- 2. Apply a slight coat of oil onto the new cartridge gasket.
- 3. To install the new cartridge, screw it in by hand. Over tightening
- may cause deformation of rubber gasket.
- 4. After the new cartridge has been replaced, the engine oil
- normally decrease a little. Thus see that the engine oil does not
- leak through the seal and be sure to read the oil level on the
- dipstick. Then, replenish the engine oil up to the specified level.
- IMPORTANT
- Q
- • To prevent serious damage to the engine, replacement
- element must be highly efficient. Use only a KUBOTA
- genuine filter or its equivalent.

- Checking Fuel Hoses and Clamp Bands
- 1. If the clamp (2) is loose, apply oil to the threads and securely
- retighten it.
- 2. The fuel hose (1) is made of rubber and ages regardless of the
- period service.
- Change the fuel hose together with the clamp every two years.
- 3. However, if the fuel hose and clamp are found to be damaged or
- deteriorate earlier than two years, then change or remedy.
- 4. After the fuel hose and the clamp have been changed, bleed the
- fuel system.
- CAUTION
- • Stop the engine when attempting the check and change
- prescribed above.
- (When bleeding fuel system)
- 1. Fill the tank with fuel and open the fuel cock (4). ([B] only)
- 2. Loosen the air vent plug (3) of the fuel filter a few turns.
- 3. Screw back the plug when bubbles do not come up any more.
- 4. Open the air vent cock (5) on top of the fuel injection pump.
- 5. If equipped electrical fuel feed pump, turn the key to AC position
- and pump the fuel up for 10 to 15 seconds.
- If equipped mechanical fuel feed pump, set the stop lever on stop
- position and crank the engine for 10 to 15 seconds.
- 6. Close securely the air vent cock after air bleeding.
- NOTE
- Q
- • Always keep the air vent cock on the fuel injection pump
- closed except when air is vented, or it may cause the engine
- to stop.
