2.15.5 Tractor Idle and Loaded Break-In
After the engine idle, power take off shaft and hydraulic system break-in tests, confirm that the mechanical state
of the tractor is normal before implementing the break-in of the whole tractor according to Tables 2-2 and 2-3.
The total break-in time is 50 hours. During idle break-in, make turns at low speed and use the one-side brake
properly. Also test the emergency brake at high speed.
After idle break-in, loaded break-in can be performed, but only if the mechanical state of the tractor is normal.
This process should be carried out with the load from light to heavy and the gear range from low to high. During
the break-in, note if:
•
The readings of electrical equipment and various instruments are normal.
•
The engine is running normal.
•
The engagement of the clutch is smooth and the disengagement is complete.
•
Gear shifting is easy and flexible, free of gear problems.
•
The brakes work reliably.
•
The connection and disconnection of the differential lock is reliable.
•
The connection and disconnection of the front drive axle is reliable.
If faults are found, repair them before continuing the break-in process.
2.15.6 Technical Maintenance after Break-In
After the break-in of the tractor, there may be some debris mixed in the oil in the transmission, the lubrication
system and the hydraulic system.
Therefore, all lubricating oil and hydraulic system oil should be drained and replaced. Take care of any necessary
technical maintenance for the tractor before putting it in to normal use. Technical maintenance after break-in
includes:
•
After the engine stops, drain the oil from the engine oil pan and the steering mechanism oil tank before it
cools down. Use approved containers to collect the used oil, and dispose of it properly.
•
Replace the engine oil filter and the diesel fuel filter, and clean the air filter.
•
Add new lubricating oil according to the technical requirements after the diesel fuel filter and the engine oil
filter are replaced.
•
After reinstalling the 3-point lift oil absorption filter, add new oil to the 3-point lift, the transmission, and the
