Maintenance Instruction
(4) When installing clutch, fill up the bearing 7(see fig.5-1) and chamber in release bearing block 6 with lithium
base grease. When dismantling the clutch, please check whether the release bearing 5 is lack of lubricant. If so,
put the bearing into heated molybdenum disulfide base grease to let the grease penetrate into bearing. When the
grease cooling down, take it out and carry out installment.
Do not clean the release bearing by putting it into
gasoline or diesel to avoid the grease in the bearing is washed away. Otherwise, refill the grease.
5.3. Brake adjustment
5.3.1 If the following items occurs, please adjust it:
Free travel of brake pedal is too large, causing brake fade.
The free travel of brake pedal is too small, causing the semi-brake state as the clearance between the brake
pad and spinning rotor is too small.
The left braking force is not consistence to the right braking force, causing tractor “Offset”.
5.3.2 Brake adjusting method:
Adjustment for free travel of brake pedal
Loosen lock nut 3 on brake bar 6, remove the split pin on the brake bar, rotate brake bar to
change the
length of the brake bar to make the free path (the displacement of the brake pedal from the highest position
to the position where the gap between the brake hub 5 and the brake shoe friction plate 4 disappears) of the
brake pedal within (20~30) mm, and make the lengths of the left and right brake bars 6 be same, then use
lock nut 3 to lock tightly. Then lock short link with lock nut 3.
Brake “Defection” adjustment
If the adjustment of left and right brakes is not consistent, the left and right tire traces will not consistent
(Viz “Deflection”) when
emergency braking during the tractor traveling at high speed. At this time, the
brake link with short trace should be properly shortened or the brake link with long trace should be properly
extended until the traces are similar and braking is reliable. Then lock the nut3.
