lubrication grease to make the lubrication grease penetrate into the bearing, take out and install it after the
lubrication grease is cooled. Do not wash the release bearing in gasoline or diesel, so as to prevent the lubrication
grease in the bearing from being washed away. Otherwise, lubrication grease must be refilled.
5.3.1 The Brake Shall be Adjusted When One of the Following Conditions Occurs:
The full stroke of the brake pedal is too large, and the brake fails;
The full stroke of the brake pedal is too small, and the clearance between the friction plate and the
partition plate is too small, so it is often in a semi-braking state;
The left and right braking forces are inconsistent, and the tractor has "deviation".
5.3.2 Adjustment of Brake:
Adjustment of free stroke of brake pedal:
To adjust the adjusting bolt (No.1) so that the height from the center of the lower edge of the pedal
surface to the floor is (123-130) mm. Adjust the length of the upper tie rod through the adjusting sleeve
(No.2) so that the angle between the lower rocker arm and the vertical direction is about 15°. Adjust the
length of the lower tie rod by adjusting the connecting rod (No.4) so that the angle between the brake
rocker arm and the vertical direction is about 5°. Make the pedal within the full stroke (75-85) mm so that
the brake can be reliably locked, and then lock each lock nuts.
Adjustment of hand brake stroke:
Adjust the length of nuts at both ends of the brake cables A and B and studs at the long fork (No.5) so
that the handbrake stroke is (115-185) mm, the brake is locked, and the parking on the slope is reliable.
Adjustment of brake "deviation":
When the adjustment of the left and right brakes is inconsistent, and the tractor brakes suddenly at
high speed, the left and right tire impressions are inconsistent in length, namely "deviation". At this time,
the brake lever on the side with short impression should be shortened appropriately, or the brake lever on
the side with long impression should be lengthened appropriately until the left and right tire impressions
are basically the same in length and can be reliably braked, and then each nut should be locked.
