3.2.2.2 Clutch dismantling
Clutch is dismantled after the engine has been detached from the transmission in
the following order:
- mount three manufacturing bolts (M12x40), having screwed them into the pressure
disk 4 (figure 3.2.2) through the manufacturing orifices of the back plate 7;
- unscrew the nuts attaching the back plate to the flywheel and remove the clutch plate as-
sembly (the back plate 7 together with the pressure plate 4);
- remove the first driven disk 2;
- remove the center plate 3;
- remove the second driven disk 2.
ATTENTION: BEFORE STARTING TO DISMANTLE THE CLUTCH IT IS RECOM-
MENDED THAT YOU MAKE MARKS, IDENTIFYING MUTUAL ARRANGEMENT OF THE
FLYWHEEL 1, THE CENTER PLATE 3 AND THE CLUTCH PLATE ASSEMBLY (THE
BACK PLATE 7 TOGETHER WITH THE PRESSURE PLATE 4). ASSEMBLE THE CLUTCH
IN ACCORDANCE WITH THE MARKS!
3.2.2.3 Clutch installation
The clutch is installed in the following order:
- mount a splined workholder in the bearing of the flywheel;
- mount the first driven disk 2 (figure 3.2.2) on the workholder with the hub long end
facing the flywheel 1;
- mount the center plate 3 in the slots of the flywheel;
- mount the second driven disk 2 on the workholder with the hub short end facing
the flywheel;
- mount the clutch plate assembly (the back plate 7 with the pressure plate 4) on the
flywheel pins with the bushings 14, fix with the nuts and unscrew the manufacturing bolts.
- adjust the position of the release levers 6.
3.2.2.4 Adjustment of clutch release levers
- screwing the adjusting nuts 9 in or out (figure 3.2.2), adjust the position of the release
levers for the dimension of (14±0,5) from the lever mounting surfaces to the face of the back
plate hub. The dimensional difference for some levers shall not exceed 0,3 mm.
- after adjustment mount the lock plates 10;
- remove the workholder.
3.2.3 Clutch drive
The clutch drive is intended to control the coupling clutch. The clutch drive type is
hydrostatic with a suspended pedal, with a hydraulic booster.
In BELARUS-1822.3/2022.3 tractors the clutch is controlled from the main control
post, in BELARUS-1822 .3/2022 .3 – from the main as well as from the reverse control
posts.
The drive consists of the following basic components:
a main cylinder for forward travel 11 (figure 3.2.6),
a main cylinder for reverse 23 (for BELARUS-1822 .3/2022 .3 tractors);
a suspended pedal for forward travel 7;
a suspended pedal for reverse 24 (for BELARUS-1822 .3/2022 .3 tractors);
an elbow fitting 45 (BELARUS-1822 .3/2022 .3 tractors have a tap 28 mounted in-
stead of the elbow fitting 45, which is intended for automatic switching from tractor operation
mode on forward travel to reverse mode and viceversa);
an operating cylinder 34;
a hydraulic booster 37;
a lever 44;
a tank 1;
connecting pipelines and hoses.
