Construction and Operation

Parking Brake
The service brakes having a separate
actuator from the control lever.
“Wet” Clutch for Locking Up the Dif-
ferential
The lock-up clutch (17) comprises six
disks with brake ceramic-metal linings
fitted on the splined boss (18) connected
with the hub drive pinion (16). A pack of
six friction and five intermediate disks is
compressed as oil under pressure is fed
to the diaphragm space. The frictional
torque developed thereby ensures inter-
locking of the rear axle differential. The
clutch is made in a single case with the
service brake. It shares a common oil
bath with the brake and is sealed by
means of the cover (20) and special cor-
rugated boot (23) slipped over the adap-
tor (21) which delivers oil to the working
space of the diaphragm.
“Wet” Brake Control
The service brakes control actuator is of
hydrostatic type.
The parking brake control is mechanical.
Brake maintenance
“Wet” brake adjustment: pedal travel
100…120 mm under the force of
(300±30) N applied to one pedal. It is
adjusted by the bolts (25).
The oil level in the brake casings shall
reach the edges of the holes of the in-
spection plugs (22) on the front walls of
the casings. The oil in the brake casings
shall be changed simultaneously with
changing of oil in the transmission.
The mark of oil to be used for the brakes
is similar to that of oil in the transmis-
sion. The draining plugs (12) located at
the bottom are provided for draining oil
from the brake casings. The oil level in
the casings shall be checked after every
500 hours of operation of the tractor.
Attention!
NEVER operate the tractor
without oil or with insufficient oil level.
