The clearance between operating
cylinder rod 34 (figure 3.2.6) and
hydraulic booster 37 follower is in-
creased
Adjust the clearance between the operating cylinder
follower and the hydraulic booster follower according
to clause 3.2.4.1 «Adjustment of clutch control»
Air presence in the clutch control
hydraulic system for forward motion
and(or) on tractors “BELARUS-
1822 .3/2022 .3” for reverse
Bleed the hydraulic system for forward motion and
for reverse
Table 7.2b finished
Failure, external manifestation,
cause
Troubleshooting
Insufficient level of hydraulic-brake
fluid in the hydraulic system tank or
on tractors
“BELARUS-
1822 .3/2022 .3»
in the main cylin-
der housing for reverse
Bring hydraulic-brake fluid level to the norm in the
main cylinder tank or in the main cylinder housing
for reverse. Bleed the hydraulic system for forward
motion and for reverse
Hermiticity breakage of the main
and operating cylinder working
cavities due to damage and wear
of cups or sealing rings (valve
damage is possible on tractors
“BELARUS-
1822 .3/2022 .3”)
Replace the cups O-rings in the main and operating
cylinder in case they are worn out. Check if the cyl-
inder bearing surface has sharpened edges,
ridges, or pits. Bleed the clutch control hydraulic
system for forward motion and for reverse
Hydraulic-brake fluid leakage in
joints or pipelines in the hydraulic
drive system. Air inflow into the
clutch control hydraulic system
Tighten up joints, replace damaged parts. Bleed
the clutch control hydraulic system for forward mo-
tion and for reverse
Clogging of opening in the tank fitting
(for forward motion) or on tractors
“BELARUS
-1822 .3/2022 .3” in the
piston (for reverse)
causing depres-
sion in the main cylinder, as a re-
sult of which air leaks into the cyl-
inder through sealings
Unclog the opening. Bleed the hydraulic system for
forward motion and for reverse
Clogging of pipelines of the hy-
draulic drive system due to dent or
blockage
Replace pipelines. Bleed the clutch control hydrau-
lic system with brake fluid
Oil leakage through O-rings of the
hydraulic booster
Replace O-rings in the hydraulic booster
Not full enough stroke of clutch
pedal (the pedal bears against the
cab wall)
Adjust the clearance between the piston and the
main cylinder piston follower for forward motion
and on tractor “BELARUS
-1822 .3/2022 .3” for re-
verse according to clause
3.2.4.1 “Adjustment of
clutch control”. Bleed the hydraulic system with
brake fluid for forward motion and for reverse. The
hydraulic booster piston stroke and accordingly,
clutch lever 44 stroke (figure 3.2.6) when fully de-
pressing the pedal shall be at least 28mm
No clutch pedal force
Air presence in the hydraulic system or the cups
and an O-ring in the main and operating cylinder
are worn out. On tractors “BELARUS-
1822 .3/2022 .3” the valve can be damaged.
Re-
place the cups and an O-ring in the main and op-
erating cylinder, the valve. Check if cylinder bear-
ing surface has sharpened edges, ridges, or pits.
