4.4.1 Rear Axle Maintenance
The main drive/driven spiral bevel gear pair for the center drive should be replaced as a matching set.
When applying the differential lock, the tractor should be driven in a straight line and steering wheel cannot be
operated, otherwise, it will cause mechanical damage.
NOTE:
When operating the tractor in reverse, the operation handle for the power output shaft (PTO)
should be put into neutral to avoid damage to the farm implement.
4.5 Brake Adjustment and Maintenance
There are two disc brake assemblies, which are symmetrically mounted on the right and left shafts of the rear axle,
and connected with the brake operation mechanism.
4.5.1 Brake Pedal Free Play Adjustment
When the brake pad assembly and the brake drum are working correctly,
the clearance betweeen them is 1–1.4 mm., and the corresponding brake
pedal free play is 90–120 mm.
When the brake pads are worn, the brake pedal free play will increase,
resulting in poor braking.
When this is the case, the brake pedal free play must be adjusted.

after adjustment.
