Before placing a new tractor in operation, do the following:
- wash the tractor, remove preservative lubricant (if any on the tractor);
- inspect the tractor carefully, check it for completeness and availability of instruction man-
uals;
- remove accumulator batteries, set them into working condition and mount back;
- check outer threaded joints for tightness and tighten more, if necessary;
- check oil level in the engine oil sump, in the transmission, in FDA case tubes, in cases of
FDA wheel gear groups, in HLL and HSC oil tanks, in FPTO reduction unit (if mounted)
and if necessary, add oil according to section 5 "Maintenance";
- check brake fluid level in the main cylinder tanks of hydrostatic clutch drives and in the
tanks of service brakes, if necessary add brake fluid according to section 5 "Maintenance";
- drain the available fuel from the fuel tank and fill the fuel tank with new settled fuel: in
winter – winter grade, in summer – summer grade;
- fill the engine cooling system with coolant to the upper edge of the radiator filler neck, fill
the expansion tank with coolant till it occupies half of the tank volume;
- check and if necessary, adjust the tire pressure to a desired value in accordance with
subsection "Selection of optimal inner pressure in tires depending on operational condi-
tions and load on tractor axles";
- make sure protective guard shields (for PTO shaft end extensions, etc.) are available;
- check engine, lighting and warning devices workability, brakes and steering control work-
ability, and functioning of other systems and units of the tractor using standard control
gages.
Before starting to run in, check tightness of retaining bolts of the hubs (the tightening
torque shall make from 360 to 450 Nm), tightness of the retaining nuts of rear wheels to
the hub (the tightening torque shall make from 300 to 350 Nm), the retaining nuts of front
wheel disks to FDA gear group flanges (the tightening torque shall make from 200 to 250
Nm) and the retaining nuts of front wheel disks to rim brackets (the tightening torque shall
make from 180 to 240 N·m).
3.4.3 Tractor run-in
ATTENTION: THE FIRST 30 HOURS OF TRACTOR OPERATION HAVE GREAT IN-
FLUENCE ON OPERATIONAL PARAMETERS AND LIFE SPAN OF THE TRACTOR.
YOUR TRACTOR WILL FUNCTION PROPERLY FOR A LONG TIME PROVIDING YOU
CARRY OUT THE RUN-IN CORRECTLY AND PERFORM OPERATIONS ON TECH-
NICAL MAINTENANCE IN TERMS SPECIFIED IN SECTION 5 "MAINTENANCE"!
ATTENTION: IT IS OBLIGATORY THAT YOU CARRY OUT TRACTOR RUN-IN FOR 30
HOURS! LOAD THE TRACTOR UP TO 80 % OF ITS RATED POWER BEFORE THE
FIRST TECHNICAL MAINTENANCE (TM-1) (125 HOURS)!
Start the engine. Let the engine run at idle speed for five minutes with gradual increase of
the rotation speed up to 1600 rpm, then run in under load for 30 operation hours.
While carrying out a 30-hour run-in, follow the instructions below:
- constantly inspect gage indications, operation of lubrication system, cooling system and
power supply system. Control levels of oil and fluids in refill capacities;
- check outer fastening links for tightness and tighten them regularly;
- do not overload the engine, avoid engine smoking and speed decrease. The features of
overload are sharp decrease of speed, smoking and absence of engine reaction to in-
