Technical Maintenance During Tractor Run-In; Technical Maintenance After Tractor Run-In - Belarus 1822.3 Operator's Manual

Start the engine. Let the engine run at idle speed for five minutes gradually increas-
ing the speed to 1600 rpm, then run in for 30 hours under load.
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 fric-
tion 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
condition 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 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 6 "Maintenance" of this manual.

4.4.5 Technical maintenance after tractor run-in

After the tractor run-in do the following:
- inspect and wash the tractor;
- listen to the operation of all tractor constituents;
- check tightening of nuts attaching rear wheels to the hub, nuts attaching front
wheels to FDA gear group 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 receivers;
- drain sediment from fuel tanks and the fine and coarse filters;
- check the state of accumulator batteries, clean terminal connections and ventila-
tion holes;
- check and if required adjust free movement of the clutch pedal, of the brake pedal
and the pneumatic drive;
- drain oil from the transmission. Then clean the rotor of the gearbox centrifugal oil
filter and the gearbox net filter. Fill the transmission with new oil;
- replace oil in the housings of the wheel gear groups and in the FDA housing;
- replace oil in the housing of the front PTO reduction unit, if available;
- replace oil in the engine sump;
- clean the rotor of the centrifugal oil filter;
- replace the engine oil filter;
- check and tighten the cylinder head fastening bolts if required;
- check and adjust the clearance between the valves and the rocker arms;
- check lubrication in all assembly units according to clause 3 of table 6.4. Where
required lubricate or replace the lubricant;
- check and if necessary restore hermiticity of the air cleaner and inlet line;
