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 the load for 30 operation
hours.
Carrying out the 30-hour run-in follow the below instructions:
- constantly inspect gauge indications, operation of lubrication system, cooling sys-
tem and power supply system. Control levels of oil and fluids in refill capacities;
- check outer fastening links for tightness and tighten them;
- do not overload the engine, avoid engine smoking and speed decrease. The fea-
tures of overload are sharp decrease of speed, smoking and absence of engine reaction to
increase of fuel feed. Operation at high gear under load results in excessive wear of friction
parts of the engine;
- tractor operation at lower gear under small load and with increased speed of the
engine will result in fuel overconsumption. Right selection of the gear for each specific con-
dition of operation ensures fuel economy and reduces engine wear-out;
- 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.
4.4.4 Technical maintenance during tractor run-in
After the first operation hour check tightening of nuts attaching rear wheels to the hub,
nuts attaching front wheels to FDA gear group flanges. If FDA 822-2300020-02/04 (basic
configuration) is mounted, please check tightening of 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 maintenance
according to the instructions, set forth in section 6 “Maintenance” of this manual.
4.4.5 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 tractor cab;
- listen to the operation of all tractor constituents;
- check tightening of all connections according to clause 4.4.4. “Technical mainte-
nance during tractor run-in”;
- tighten two lock nuts M27x1,5 (with left and right thread) of the steering link tube
with a torque of 100 to 140 Nꞏm 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 Nꞏm, 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 receivers;
- drain sediment from fuel tanks and the engine coarse filter;
- check the state of accumulator batteries, clean terminal connections and ventilation
holes;
- check and if required adjust free movement of the clutch pedal, of the working and
parking brakes control and brake valve drive of pneumatic system;
- change oil in transmission;
- on tractors with FDA822-2300020-02/04 (basic configuration) change oil in housings
of wheel hub drives, FDA case and intermediate bearing of FDA cardan drive.
- on tractors with FDA 72-2300020-А-04 change oil in upper and lower bevel gear and
pinion groups of FDA wheel hub drives, FDA case and intermediate bearing of FDA cardan
drive.
- replace oil in the engine crankcase;
