2.18.5 Break-in
– No Load
After breaking-in with the power output shaft and the hydraulic suspension, the entire tractor should be
run in. During idle break-in, make turns at low speed using the single-side brake and also test the emergency
brake at high speed.
The break-in sequence and time required should be done in accordance with the
specifications defined in table 2-2.
While performing break-in operations, the rotary speed of the engine should be 1500 rpm. During break-in,
pay attention to the following:
Check to see if the electrical equipment and the readings for various instruments are normal.
Make sure that the engine is running normally.
Check to see that the clutch engages smoothly, and disengages completely.
Make sure that the shifting is easy and flexible and that it stays in gear.
Check the brakes for proper function.
Check the Differential Lock engagement and disengagement.
That the engagement/release of the front axle is reliable.
If any faults are found, troubleshoot immediately before continuing the running in process.
