Iseki TG5330 / TG5390 / TG5470 service schedule

1. Park level, lower the linkage, stop the engine and take the key out.
2. Clean the grease gun nozzle and each fitting before greasing so no dirt is pumped in.
3. Grease every fitting shown in the handbook's lubrication chart until fresh grease shows, then wipe them clean.

Tools: Grease gun, Rags

1. Park on level ground, lower the linkage, stop the engine, take the key out and chock the wheels.
2. Drain the oil while the engine is warm but not hot. Hot oil burns, so wear gloves.
3. Remove the drain plug, let it drain fully and refit it.
4. Unscrew the filter and check the old gasket came off with it. Oil the new gasket with clean engine oil, screw the filter on until the gasket touches, then a further half turn.
5. Refill the crankcase slowly so air can vent, to between the F and L marks on the dipstick.
6. Start the engine, check for leaks, stop it, let it settle and top up. Check the level only with the engine cool and the tractor level.

Tools: Drain tray (10 L), Spanner for drain plug, Filter wrench, Funnel, Rags, Gloves

1. Park level, stop the engine, take the key out and chock the wheels.
2. Remove the clutch chamber drain plug and let out any water or oil, then refit it.
3. Check the clutch pedal free play and, every second time, the brake pedal play. Adjust to the figures in your handbook, or ask your dealer.

Tools: Spanners, Rule

1. Park on level ground and stop the engine.
2. Most tractors: remove the level plug. Oil should be level with, or just below, the opening. If low, remove the fill plug and add oil until it runs out of the level hole, then refit both plugs.
3. Early TG5330 (serial 000061–000729) and TG5390 (serial 000146–001025): remove the fill plug; oil should reach the top of the shaft. Top up to there and refit the plug.

Tools: Spanner for plugs, Funnel

1. Stop the engine, take the key out and keep flames away. Turn the fuel valve OFF (handle towards the front).
2. Loosen the ring nut and take off the sediment bowl and its O-ring. Clean the bowl.
3. Pull the element down and throw it away. Check the small O-ring in the filter head and replace it if needed.
4. Push the new element up until it seats, refit the bowl O-ring and nut, tighten it and wipe up any fuel.
5. Turn the fuel on and bleed the fuel system as the handbook shows. Do not alter the injection pump or injector settings.

Tools: Clean tray, Rags, Container for fuel

1. Park on level ground, stop the engine, take the key out and chock the wheels. Lower the three-point linkage completely before draining.
2. Remove the drain plug and drain the system completely, then refit the plug.
3. Unscrew the filter, using a filter wrench if needed. Clean the adapter and oil the new filter's seat.
4. Fit the new filter until the gasket touches the adapter, then a further 2/3 turn by hand. Do not tighten it with a filter wrench. The cartridge contains magnets.
5. Fill through the filler plug until the oil shows in the level window.
6. Run the engine briefly, stop it, recheck the window and top up. Check for leaks.

Tools: Large drain tray (40 L), Spanner for drain plug, Filter wrench (for removal only), Funnel or pump, Rags

1. Park on level ground, stop the engine, take the key out and chock the wheels.
2. Remove the drain plug from both wheel reduction units and let the oil drain.
3. Refit the drain plugs and fill to the level plug opening (or to the top of the shaft on the early models listed in the level check job).
4. Refit the level and fill plugs.

Tools: Drain tray, Spanner for plugs, Funnel

1. Book the tractor into an Iseki dealer for the valve clearance check every 600 hours.

Tools: Dealer

1. Stop the engine and take the key out. Open the bonnet and remove the left side cover and front grille.
2. Press the vacuator valve to let dirt out, and wipe any moisture from inside the housing.
3. Unclip the element and take it out. Dry dust: blow air from the inside out at no more than 200 kPa (30 psi), or tap it gently by hand. Never knock it on anything hard.
4. Oily or damp dirt: soak about 30 minutes in water with a neutral detergent, rinse and let it dry naturally, without compressed air or heat.
5. Replace it if the paper, canister or seal is damaged, or after 5 washes. Push the element straight back in so it seats.

Tools: Compressed air (under 200 kPa / 30 psi), Neutral detergent, Rag, Dust mask

1. Let the engine cool. Do not open the radiator cap except to check or change coolant; hot coolant can spray out.
2. Open the drain cock on the right of the engine and the radiator cap. Remove the reserve tank and drain it.
3. Flush the radiator well with clean water, then close the drain cock.
4. Refit the tank and fill through it to FULL. Close the radiator and tank caps.
5. Run the engine about 5 minutes at around 1,500 rpm and stop it. When it has cooled, top the reserve tank up to FULL, but not above.
