Oil ingress into the brake causes greas-
ing of disks, reduced friction between
their brake friction areas; the brakes
«fade». In this case, dismantle the brake,
eliminate oil leaks, and wash the greased
disks in petroleum, then, let them dry for
5-8 min. Following brake reassembling,
re-adjust brake controls.
7.6.5. ADJUSTING THE PARKING
BRAKE
To adjust the parking brake, proceed as
follows (see Fig. 54):
а) set the parking brake control lever to
its forward position (push away from
you);
b) loosen tightening of the adjusting
bolt (1) lock-nut, as well as lock-nut
(7), and take out pin (5);
c) turn lever 4 and register the upper
edge of slot
В
1
in lever 2 with the
upper edge of slot
В
2
in lever 3 of
the right-hand brake pedal. Then, ro-
tating fork 6, register holes in the
lever (4) and fork (6); insert pin (5);
d) turn the bolt 1 in or out, so that,
when pulling the control lever at a
force of 400 N, the catch is retained
in the space between the third and
fourth teeth of the sector, and the
tractor is held good at a 18-percent
steep grade. With the adjustment
completed, tighten up all the lock-
nuts which have been slackened be-
fore.
7.6.7. ADJUSTING THE REAR P.T.O.
CONTROL MECHANISM
When assembled at the factory and after
repair (e.g. after replacement of the
Fig. 54
brake bands), the P.T.O. control mecha-
nism should be adjusted in the following
order of operations:
1. Set the eccentric axle (15) (see Fig.
56) to the initial position, so that flat
«
В» is to the right, in vertical posi-
tion; lock it with lock plate 17 and
bolt 16;
2. Disconnect tie-rod (4) (see Fig. 55);
3. Screw out bolt 9 to release spring
6;
To ensure safety when dismantling the
unit, see to it that the upper cup (7) is in
constant contact with the bolt (9) when
the latter is being screwed out, until the
spring is fully released.
4. Remove the rear axle hatch lid to
gain access to screws (13);
5. Lock the lever 11 in the neutral po-
sition, by inserting a
М10Х60 bolt,
or 8-mm rod, 10 into the hole in the
lever and a corresponding hole in
the rear axle housing;
