Note: The tractor's left and right brake pedal strokes must be adjusted to the same, otherwise the tractor
will deflect sharply to one side during emergency braking, which will cause accidents.
5.4.1 Adjustment of Pre-tightening of Cone Bearing
After a period of use, the original preload will gradually disappear due to bearing wear, and there will be
clearance between two bearings. When the clearance is more than 0.1 mm, the cone bearing should be
pre-tightened again.
Adjustment of the pre-tightening of the second shaft cone bearing: Adjust the tightening degree of the
lock nut 1 close to the cone bearing 4 so that the torque for rotating the second shaft 5 alone is (0.7 ~ 1.1)
N·m. After adjustment, lock the tab washer 2 and tighten the lock nut 1.
Adjustment of pre-tightening of differential cone bearing
Add (or reduce) the same amount of adjusting washers 13 between the two sides of the transmission case and the
bearing seats of the cone bearing, tighten the bolts of the two bearing seats and rotate the second shaft. If the
rotating torque is larger than that when the differential is not installed (0.4 ~ 0.7) N·m, its pre-tightening is
appropriate. At this time, push the bevel gear axially, and there should be no movement.
