6.4.5.7 Operation 64. Change of hydraulic-brake fluid in the clutch control drive
WARNING: EXCLUDE CONTACT OF HYDRAULIC-BRAKE FLUID WITH EYES
AND UNCOVERED SKIN AREAS!
ATTENTION: EXCLUDE INGRESS OF MINERAL OIL, PETROLEUM, KEROSINE
AND DIESEL FUEL INTO HYDRAULIC-BRAKE FLUID, AS THESE SUBSTANCES RE-
SULT IN SWELL OF RUBBER GASKETS!
To change hydraulic-brake fluid in the clutch control drive of tractors “BELARUS-
1822 .3/2022 .3”, it is required to do the following:
1. Drain hydraulic-brake fluid from the hydraulic system performing the following ac-
tions:
- unscrew tank cap 1 (figure 3.2.6) of the forward motion main cylinder 11 and open
casing 17 of reverse main cylinder 23;
- dismount safety cap 32 from bypass valve 33;
- put the rubber hose on the bypass valve dipping its loose end into an empty con-
tainer;
- turn bypass valve 33 for one revolution;
- press clutch pedal for forward motion 7 several times until the hydraulic-brake fluid
is fully extracted from the forward motion hydraulic system;
- press reverse clutch pedal 24 several times until the hydraulic-brake fluid is fully
extracted from the reverse hydraulic system;
- screw in bypass valve 33, dismount the hose, put on safety cap 32 back in its
place.
2. Fill tank 1 of forward motion main cylinder 11 with hydraulic-brake fluid up to
mark “Max” on the tank and the compensation chamber of reverse main cylinder 23 with
hydraulic-brake fluid up to the level 10…15mm from the compensation chamber upper
edge.
3. Bleed the hydraulic system of clutch control according to clause 3.2.4.2 of sub-
section 3.2.4 “Clutch control adjustment”
4. Put tank cap 1 and casing 17 back in their places.
Change of hydraulic-brake fluid in the clutch control drive on tractors “BELARUS-
1822.3/2022.3” is carried out in a similar way with the exception of the actions connected
with hydraulic-brake fluid draining and filling, and bleeding of the clutch control hydraulic
system for reverse for the reason of absence of the reverse control station on tractors
“BELARUS-1822.3/2022.3” and accordingly absence of clutch control hydraulic system
circuit for reverse.
