Check the engine for normal running.
Check the clutch for smooth engagement and complete release.
Check the gearbox for easy and flexible gear shift without disordered gear engagement or automatic gear
disengagement.
Check the brake for reliable operation.
Check the differential lock for reliable locking and unlocking.
Check the front drive axle for reliable engagement and release.
When faults are detected, eliminate them and then go on implementing running-in.
3.15.6 Technical maintenance after running-in
After tractor running-in, there will be some metal particles or contaminations mixed with lubricant of the drive
system, lubrication system and hydraulic system. Therefore, it is nec
essary to carry out cleaning and change all
lubricant and hydraulic system oil. Tractors are allowed to be put into service only after the completion of
necessary technical maintenance.
Technical maintenance content is as follows after running-in:
After st
opping engine that is still hot, please immediately drain the oil in the engine oil sump and steering
oil reservoir. Clean the oil sump, oil filter screen, filter screen from diesel filter, oil filter, air cleaner and
steering oil reservoir. After replacing filter elements of diesel and oil filters. Fill the new lubricant as
technically required.
Also immediately drain the oil in the drive system, lifter and front drive axle to add proper light diesel
engine or kerosene. Without starting engine, drag the tr
actor forward or backward at low speed for 3min. Or
jack up the front and rear wheels to let them free of ground, rotate the front and rear wheels forward and
backward for 3min, and then drain the cleaning solution timely. Dismantle the oil absorption filter of lifter
to clean. After reinstalling, fill the drive system and front drive axle with the new lubricant as required.
Please service the diesel engine according to “Diesel engine use and maintenance instruction”.
Drain the cooling water, wash the engine cooling system with clean water and add new coolant.
Check the toe-in of front wheel, clutch, free travel of brake pedal, adjust it if necessary.
Check and tighten all bolts, nuts and screws outside of tractor.
For adding the grease, please refer to technical maintenance sheet.
Important:
1. In the case of tractors just leave the factory or be overhauled, they should be put into service after running-in
or their service life will be shortened.
2. Drivers should learn and master control method and usage of tractors before implementing tractor running-in.
Otherwise, there will be accidents as results of misoperation.
