Start the engine. Let the engine run at idle speed for five minutes with gradual in-
crease of the rotation speed up to 1600 rpm, then run in under load for 30 operation hours.
When carrying out the 30-hour run-in, follow the below instructions:
- constantly monitor gauge indications, operation of lubrication system, cooling sys-
tem and power supply system. Control levels of oil and fluids in refill capacities;
- regularly check outer fastening links for tightness and tighten them;
- do not overload the engine, avoid engine smoking and speed drop. The features of
overload are sharp decrease in speed, smoking and absence of engine reaction to in-
crease in fuel feed. Operation at high gear under load results in excessive wear of friction
parts of the engine;
- tractor operation at unduly low gear under small load and with increased speed of
the engine will result in fuel overconsumption. Right selection of the gear for each specific
condition of operation ensures fuel economy and reduces engine wear;
- avoid prolonged engine operation without load in a mode of max. or min. speed of
the engine;
- for correct break-in of the clutch friction parts during the run-in process, engage
the clutch more often and more smoothly.
ATTENTION: EXHAUST GASES HAVE OUTPUT TEMPERATURE FROM 500 TO
600°С, THEREFORE DAMAGE OF PAINT-AND-VANISH COATING OF EXHAUST MAN-
IFOLD AFTER FIRST ENGINE OPERATING HOURS IS NOT A SIGN OF MALFUNC-
TION IN ENGINE OPERATING PROCESS.
3.4.4 Technical maintenance during tractor run-in
After the first run-in hour check tightening of nuts attaching rear wheels to the hub,
of nuts attaching front wheels to FDA reduction unit flanges and nuts attaching the front
wheel disks to the rim brackets. Then inspect the wheel tightening every eight hours during
the run-in.
In the run-in process, regularly carry out operations in shift-time technical mainte-
nance according to the instructions, set forth in section 5 “Maintenance” of this manual.
3.4.5 Technical maintenance after tractor run-in
After the tractor run-in do the following:
- perform shift-time maintenance operations;
- inspect and wash the tractor, clean the cab inside;
- make sure visually, that pipelines, aggregates of lubrication, feeding and cooling
systems are leak-proof. Tighten the connections, if necessary;
- listen to the operation of all tractor constituents;
- check tightening of nuts attaching rear wheels to the hub, nuts attaching front
wheels to FDA reduction unit flanges and nuts attaching the front wheel disks to the rim
brackets;
- tighten two lock nuts M27x1,5 (with left and right thread) of the steering link tube
with a torque of 100 to 140 N·m and two crown nuts M20x1,5 of the steering link ball pins.
To tighten the crown nuts, remove the cotter pin first, tighten each crown nut with a torque
of 100 to 140 N·m, then turn each crown nut until the nearest notch on the nut coincides
with a hole in the ball pin and then fasten with a cotter pin.
- check and if necessary tighten outer threaded links;
- drain condensate from the pneumatic system receiver;
- drain sediment from fuel tanks and the coarse fuel filter;
- check the state of accumulator battery, clean terminal connections and ventilation
holes;
