Instead of the “BOSCH” integrated unit your tractor may be equipped with a hydrau-
lic unit 70-1523.1, introduced in figure 3.15.6.
If the tractor is equipped with the hydraulic unit 70-1523.1, the first section spool,
that can be fixed in positions “uplift”, “neutral” and “floating”, doesn’t have the option of
automatic return from the position “uplift” to the position “neutral” as the preset pressure is
achieved. With the hydraulic unit
70-1523.1 installed, it is required to return the lever to
the “neutral“ position manually after the “uplift” operation has been carried out.
1 – 1- ; 2 – 70-8-0- ; 3 – 70-20.

3.15.5 Installation and adjustments of position and force sensors of RLL ECS
3.15.5.1 General information
A position sensor 8 (figure 3.18.1) and force sensors 10 and 11 serve to ensure posi-
tion, draft and combined control of the RLL, as specified in subsection 3.18 “Rear lift linkage
electronic control system”.
3.15.5.2 Installation and adjustment of the position sensor
The BELARUS – 1822.3/1822 .3/2022.3/2022 .3 tractor may be equipped with po-
sition sensors of “BOSCH” company or with position sensors -01 manufactured by “Iz-
meritel” plant.
The position sensor 6 (figure 3.15.7 and 3.15.8), be it “BOSCH” or -01 of “Izmer-
itel” plant, is screwed into a hole in a cover 4 of the rear axle and is controlled by a cam 3,
attached to a turn shaft 2.
To install the “BOSCH” sensor proceed as follows:
o
raise the RLL to the extreme upper position, herewith the sensor ball shall stay
opposite a mark “A” or a little displaced to a mark “ ” (figure 3.15.7);
o
if this is not effected; release a screw 1 and turn the cam 3 by a required angle,
tighten the screw 1;
o
screw the sensor 6 in manually to the end of its thread, then turn it out by
0.5…1.0 rev. and lock with a nut 5. If the sensor is installed correctly, the indicator of the
RLL uplift goes out as the RLL reaches its extreme uplift position.
ATTENTION: DO NOT WRENCH THE NUT 5 OFF IN ORDER NOT TO DAMAGE
THE SENSOR 6, MADE OF ALLUMINIUM ALLOY!
ATTENTION: OPERATION OF “BOSCH” SENSOR IS POSSIBLE ONLY IN A SET
WITH A CAM OF “BOSCH” COMPANY!
