Repair guides
- AdBlue (SCR) warnings: DEF filter, breather filter and sensor pre-filter (Specialist, 1–2 hours for the filter changes; dosing, sensor and heater faults need a dealer): AdBlue dosing or quality warnings, reduced engine power linked to the SCR system, an AdBlue filter that is due, or an AdBlue tank that will not vent properly.
- Poor starting, power loss or water in the diesel: fuel pre-filter and filter change (Moderate, 45 minutes to 1½ hours): Engine hard to start or cuts out, loss of power, a water-in-fuel warning, or fuel filters that are due. Water ruins common-rail injectors, so do not carry on running with a water warning.
- Air system: water in the tanks, slow pressure build-up, air dryer cartridge (Moderate, 30–60 minutes): Water running out of the air tank drain, the compressor running very often, slow air build-up for trailer brakes, or a compressed air leak warning.
- Wheel nuts and front axle toe-in: checking after a tyre or axle job (Moderate, 1–2 hours): Front tyres wearing on the inside or outside edge, steering that wanders, loose or clicking wheels, or a tyre or axle job just completed.
- Belt squeal, overheating or a weeping water pump: belts, tensioner, pump and fan bearings (Moderate, 1–2 hours): A squealing or flapping belt, a charging or air-con fault, engine running hot, coolant weeping from the water pump weep hole, or a rumble from the fan area.
The full step-by-step guides are in Farmyard Workshop once you add your tractor.
