Preventive/scheduled maintenance instructions 1. The maintenance of tractor when done and correctly carried out, ensure, the trouble free tractor performance. 2. The following instructions are to be observed carefully:- GENERAL PRECAUTION (a) Daily Task (to be carried out after each 8-10 hrs of operation of tractor). (i) Clean both the tractor and implements. (ii) Replenish fuel and inspect for tightness of the fuel system. (iii) Check water level and inspect for tightness joints of the cooling system. (iv) Check oil level and inspect for tightness joints of lubricating system. (v) Check oil level in the air cleaner and clean the pre- filter removing dust from it. (vi) Check function both of the foot and of hand brake. Check brake liquid level in the jar and hydraulic brake system for tightness. (vii) Inspect the condition of the electrical installation, Check lights trafficator etc. Check the regulator run of running engine, correct lubrication and charging. (viii) Check air pressure in the front and rear tyres, screw on caps and tighten them well. (ix) Check if screw, blots and nuts of the steering system linkage and leverage and discs both of the front and rear wheels. (x) Check if water pump drive V-belt as well as that of the dynamo are tightened well and correctly. (for sag see Para 2 (a) (v) ). (xi) Before starting to drive the tractor with trailor or trailor in toe, check their state as well as the state and condition of coupling and locking elements. (xii) When starting to employ the hydraulic power lift, unscrew the magnetic oil cleaner from its housing. Rinse and blow off the screen and clean magnet. It is recommended to inspect and clean the magnetic oil filter during the starting period of the hydraulic power lift service. Check each 30-50 engine hours the oil level in the injection pump. (b) After every 500 litres fuel consumption or after each 100 engine hours. All operation mentioned in Para 2 (a) (i) to (xii) above to be carried out at first.

(ix) Lubricate the Bowden cable at braked tractor by means of the hand brake with few drops of oil SAE 30.
(c) After every 1000 litres fuel consumption or after each 200 engine hours. All operation mentioned in para 2 (a) (i) to (xii) and 2 (b) (i) to (ix) above to be carried out at first. (i) Change oil in the crankcase oil sump, injection pump body and the governor. (ii) Clean duly the centrifugal oil cleaner. (iii) Replace the cartridge of the coarse fuel filter. (iv) Check clearance between the clutch disengagement levers and the sleeve. (v) Inspect and necessary clean and set up the injector. Inspect the oil level and replenish if necessary the steering box. (d) After every 3000 litres of fuel consumption or after each 600 engine hours. All operation mentioned in Para 2 (a) (i) to (xii), (b) (i) to (ix) and (c) (i) to (v) above to be carried out at first. (i) Replace the fine fuel filter cartridge. (ii) Check valve clearance in a field wksp on the cold engine – both intake and exhaust valve of 0.25+0.05 mm. (iii) Check the front wheel toe-in and the divergence as well as the play of the front wheel heads taper roller bearings, replenish the grease in the front wheel heads. (iv) Check and adjust the hand brake if necessary. (v) Flush the cooling system under the pressure of pure water in order to remove sediments. (e) After every 6000 litres of fuel consumption or after each 1200 engine hours. All operation mentioned in Para 2 (a) (i) to (xii), (b) (i) to (ix),(c) (i) to (v) and(d) (i) to (v) above to be carried out at first. (i) Change oil in the steering box (ii) Change oil in the portals. (iii) Change the suction strainer of the oil pump. (iv) Have checked tightness of the injection pump elements in a Fd wksp. (e) After every 12000 litres of fuel consumption or after each 1200 engine hours. All operation mentioned in Para 2 (a) (i) to (xii), (b) (i) to (ix),(c) (i) to (v) ,(d) (i) to (v) and,(e) (i) to (v) above to be carried out at first. (i) Check or have repaired the steering wheel play according to the steering wheel dead point position. (ii) Check the charging unit and the starter motor by Fd Wksp.
