3. Remove both filters. Do not fill the new ones with fuel.
4. Wet the seals with fuel, fit the filters and tighten as marked on the filter, then plug the sensor back in.
5. Turn the key to ON for 60 seconds to fill the filters, then start and run at fast idle for 2 minutes. Check for leaks.

Tools: Container for fuel, Filter wrench, Rags, Gloves

1. Run the engine to warm the oil, then stop it. Park on level ground, apply the park brake, lower the linkage and any implement to the ground, stop the engine, take the key out and chock the wheels.
2. 9230: open the engine drain valve into a large pan. Do not remove the relief valve plug on the filter housing. Undo the filter cap with a 32 mm spanner, lift out the cap and filter, knock the filter out of the cap, fit the new O-ring and filter, and tighten the cap to 40 N·m.
3. 9330–9630: turn the crankcase drain fitting to drain the oil, then tighten it. Remove the filter and old gasket, clean the mounting face, oil the new gasket and fit the filter hand-tight, no more.
4. Refill with oil, start the engine, check for leaks, stop it and recheck the level.
