Kubota B2410 / B2710 / B2910 service schedule

1. Park level, lower the linkage, stop the engine and take the key out.
2. Wipe each nipple clean and grease the HST (speed control) pedal, right lifting rod, top link, both knuckle shafts and the front axle support.
3. Put a light film of grease on the battery terminals.
4. Wipe off the excess.

Tools: Grease gun, Rags

1. Stop the engine and take the key out. Never run it with the element out.
2. Take off the cover and the primary element. Leave the secondary element in place unless you are replacing it.
3. Dry dust: blow air from the inside out while turning the element, keeping the pressure under 686 kPa (99 psi).
4. Carbon or oil on it: soak 15 minutes in detergent, wash several times in water, rinse and let it dry naturally. Check it inside with a torch for damage.
5. Never oil this dry element. Refit the dust cup with its arrow upright so the evacuator valve works. Open the evacuator valve weekly, or daily in dust.

Tools: Compressed air (under 686 kPa / 99 psi), Torch, Mild detergent, Dust mask

1. Park on level ground, lower the linkage and any implement, stop the engine, take the key out and chock the wheels.
2. Warm the engine for about five minutes first so the oil drains well, then stop it. Hot oil burns, so wear gloves.
3. Remove the drain plug, let the oil drain fully and refit the plug.
4. Unscrew the old filter. Smear clean oil on the new filter's rubber seal and screw it on by hand only; over-tightening distorts the seal. Use a genuine Kubota filter or its equivalent.
5. Fill with new oil to the upper line on the dipstick. If you change brand or grade, drain all the old oil out; never mix two types.
6. Run the engine briefly, check for leaks at the filter seal, stop it and top up to the upper line.

Tools: Drain tray (5 L), Spanner for drain plug, Filter wrench, Funnel, Rags, Gloves

1. Do this in a clean place, not in the field. Stop the engine, take the key out and keep flames away.
2. Make sure the tank is less than half full, or fuel can run back from the return pipe when the bowl is off. Close the fuel tap.
3. Unscrew the ring, take off the bowl and rinse it and the element in kerosene.
4. Refit everything, keeping dust out, open the tap and bleed the fuel system.

Tools: Clean tray, Kerosene (paraffin), Rags

1. Park on flat ground, set the parking brake, stop the engine and take the key out.
2. Lightly press the pedal and measure the free travel at the top: 20–30 mm. At the stopper bolt it should be 1.0–1.5 mm.
3. If it is out, change the length of the clutch pedal rod and lock it, then secure the stopper bolt with its lock nut.

Tools: Rule, Spanners

1. Only work on a cold engine; hot coolant scalds.
2. Check the radiator hoses and clamps; replace any that are swollen, hard or cracked.
3. Check the fuel pipes and clamps. Cap open ends with clean cloth while working, and bleed the fuel system after changing any part.

Tools: Screwdriver, Torch

1. Stop the engine, take the key out and chock the wheels.
2. Press the belt midway between the pulleys with moderate thumb pressure: it should move 7–9 mm. To adjust, slacken the alternator bolts, lever the alternator out and retighten.
3. Release the parking brake and measure each brake pedal's free travel: 30–40 mm, and the two sides must be within 4 mm of each other.
4. To adjust, slacken the lock nut, turn the turnbuckle to change the rod length and retighten.

Tools: Rule, Spanners, Lever bar

1. Park on level ground, lower the linkage and any implement, stop the engine, take the key out and chock the wheels. Let the oil cool enough not to burn you.
2. Put the tray under the tractor and remove the drain plugs at the rear axle cases and the oil tank. When it has drained, refit all three plugs.
3. Remove the filter cartridges. Oil the new gaskets lightly and screw the new ones on by hand; over-tightening deforms the gasket. Use genuine Kubota filters or equivalent to avoid hydraulic damage.
4. Take out the transmission oil strainer, wash it in non-flammable solvent, check its O-ring and refit the strainer first before the cartridge.
5. Remove the filling plug and fill with Super UDT to the upper notch on the dipstick. Do not mix brands or grades.
6. Do not work the tractor straight away: run the engine at medium speed for a few minutes, stop it, recheck the level and top up. Check the filter seals for leaks.

Tools: Drain tray (20 L), Spanners for the three drain plugs, Filter wrench, Non-flammable solvent, Funnel

1. Park on level ground with tyres at the right pressure, wheels straight, implement lowered, parking brake on and engine off.
2. Measure between the tyre beads at hub height at the front and the rear of the front tyres. The front figure should be smaller by the amount above.
3. To adjust, slacken the tie rod lock nuts, turn the tie rod and retighten.
4. Check the intake air hoses and clamps for tightness and damage.

Tools: Tape measure, Spanners

1. Park on level ground, stop the engine, take the key out and chock the wheels.
2. Remove the drain plugs on both sides and the filling plug (and the breather plugs on bi-speed turn axles) and drain the oil.
3. Refit the drain plugs and fill with new oil to the upper notch on the dipstick.
4. Wait about 10 minutes, recheck the level and top up. Refit the filling and breather plugs.

Tools: Drain tray, Spanners for plugs, Funnel

1. Stop the engine, take the key out, keep flames away and close the fuel tap.
2. Unscrew the ring, take off the bowl and rinse it in kerosene.
3. Fit the new element, refit the bowl, open the tap and bleed the fuel system.

Tools: Clean tray, Kerosene (paraffin), Rags

1. Park level, stop the engine and chock the rear wheels.
2. Take off the front wheel hub cover, apply bearing grease and refit the cover.

Tools: Screwdriver or puller for hub cover, Grease gun

1. Check the valve clearances on a cold engine to the figure in the workshop manual.
2. Have the injectors tested every 1,500 hours and the injection pump every 3,000 hours by a Kubota dealer or diesel specialist.

Tools: Feeler gauges, Dealer test equipment for injectors and pump

1. Let the engine cool fully. Never open the radiator cap hot.
2. Open the drain cock, remove the cap and drain the coolant.
3. Flush with cleaner and water as the cleaner says, then drain again.
4. Fill with clean soft water and antifreeze (under 50%), fill the recovery tank, run the engine, let it cool and top up.

Tools: Drain tray, Funnel, Antifreeze tester
