Fuel System Clean Diesel Fuel Diesel Fuel should be poured so that no sediment can enter the tractor fuel tank whilst it is being filled. Fuel storage facilities should allow for the periodic removal of sediment from the bottom of the storage tank. The Diesel fuel filters will remove any sediment still present in the fuel and ensure that the fuel reaching the injection pump and injectors is free of impurities. The fuel filter should be serviced regularly to ensure maximum engine reliability. Bleeding the Fuel Filter The presence of air in the fuel can cause fuel stoppages. The air should be completely bled so that the tractor operates satisfactorily. Loosen air bleeding screw (B) on fuel filter and push hand primer (A) down till you get the flow of fuel free of air from air bleeding screw. Retighten the screw (B).
Escaping hydraulic diesel fluid under pressure can penetrate the skin causing serious injury. Do not use your hand to check for leaks. Use piece of cardboard or paper to search for leaks. Stop engine and relieve pressure before connecting or disconnecting lines. Tighten all connections before pressurizing lines. If any fluid is injected into the skin obtain medical attention immediately or else, serious injury may result.

Bleeding the Fuel Injection Pump Loosen the High-Pressure pipes at the nozzle end. Operate the hand primer (A) on fuel filter till you get a streamline flow of fuel from the High-Pressure pipes. Retighten the High-Pressure pipes and start the engine. Observe till the engine runs smoothly and then shut-off till further use.
Tractor Front
Fuel Tank and Fuel Pipes Fill the tank each time the tractor finishes the days work. This prevents condensation inside the fuel tank. Check regularly to ensure all fuel pipe unions are tight and in good order. Ensure that vent hole provided on fuel tank cap is not choked. Water or dirt settled in the bottom of fuel tank should be drained daily, before starting the engine by loosening the drain cock till clean diesel flows.
Tamper Proofing Calibration of Fuel Injection Pump calibration plays a vital role in Engine performance and hence the same shall not be disturbed by unauthorised persons. In order to prevent tampering, a tamper-proof arrangement is provided on Fuel Injection Pump consisting of SPECIAL SEALS (C). Any FIP related work should be carried at Mahindra / BOSCH authorised dealership.
