Repair guides
- 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.
- Lacking pulling power: engine or transmission? Pressure measurement and owner checks (Fendt 900 Vario COM III) (Specialist, Owner checks 1 hour; the full measurement is a workshop job): The tractor feels weak in the field or on the road, wheels slip or the engine pulls down easily, even though the engine seems to run well. Or the Vario shows high-pressure faults.
- Transmission oil top-up after opening the high-pressure side (Fendt 900 Vario COM III) (Specialist, 1–2 hours): Needed after the transmission has been rebuilt, or after high-pressure valves or the purge valve have been removed and the high-pressure unit has run empty. Also the routine oil top-up at service time.
The full step-by-step guides are in Farmyard Workshop once you add your tractor.
