The brake has been adjusted before leaving the manufacturer. The left and right pedals can
be easily linked together or separated. In the case of locking together, the left and right drive
wheels can be braked simultaneously when the pedals are stepped down. Wearing of the brake
friction disk can cause the free travel longer and unindentical brake of the two wheels. At the
moment, it is necessary to adjust it.
When adjusting, loosen the locking nut (4) as shown in Fig.6--6, and turn the adjusting nut
(5) clockwise to reduce the free travel , and vice versa. When the free travel is very long, change
the length of the pull rod (3), and keep the same free travel of the left and right brake pedals.
Lock the licking nuts(2) and(4) to keep from any loose affecting the braking work after the pedal
has been adjusted to the specific free travel. When the two rear wheels brake unidentically, the
left and right
brakes should be adjusted simultaneously after the one ,capable of braking, has
been loosened. Never rashly shorten the length of the one incapable of braking. In case of oil dirt
on the friction plate, gasoline should be selected to clean it. In case of a plate being severely
burnt or worn to the pin, a new plate should be replaced.
Caution :When the tractor is driven on road , single -side-braking is forbidden, and the left
and right brake pedals should be locked together by a interlock.
VI. Steering Gear.
BY--350 and BY 400 tractors adopt circulating ball steering gear of mechanical screw and
nut, and BY 354 and 404 tractors adopt separating fully hydraulic steering gear. Before leaving
factory, the stipulated travel of the steering gear has been adjusted, less than 30
0

A. Adjustment of steering Mechanism.
a. Adjustment of bearing clearance.
b. To keep the steering in normal working condition, bearings at the two extremities of the worm
rod must be pre-fastened. The clearance caused by wearing, can be eliminated by adjusting the
washer between the steering gear, the upper cover (2) and the case (3).The pre-fastening
suitability means that the steering wheel can be moved when the steering rocker arm (7), is not
fixed and the force applied on the steering wheel is 3--5 N.
c. Backlash adjustment of gear sector and gear rack.
d. Due to wearing of gear sector and gear rack in operation, the backlash of the gear mesh is
increased , which also causes the free travel increased. It should be adjusted when the free
