6. POSSIBLE FAILURES AND INSTRUCTIONS FOR THEIR TROUBLESHOOT-
ING
6.1 Possible clutch failures and instructions for their troubleshooting
The list of possible failures of tractor "BELARUS-2022.6" and instructions for their
troubleshooting are shown in table 6.1.1.
Table 6.1.1.
Failure,
external manifestation, cause
Clutch coupling does not transmit full torque ("clutch skidding")
There is no clearance between the
clutch release bearing and release lev-
ers – "clutch is half disengaged" (insuf-
ficient clutch pedal free travel)
Partial engagement of clutch coupling
(clutch lever 35 (figures 5.4.21 and
5.4.22) fails to return to its initial posi-
tion) when the clutch pedal is released,
due to failure in clutch operation control
Clutch driven disk facings are worn out
Clutch driven disk facings are oiled-up
due to ingress of oil into the dry section
Poor compression spring force (spring
shrinks due to continuous skidding and
clutch overheating)
Clutch coupling can not be fully disengaged ("clutch grabs and shudders")
Clearance between the clutch release
bearing and release lever is increased
(increased clutch pedal free travel)
Insufficient clutch lever 35 travel (fig-
ures 5.4.21 and 5.4.22) when the clutch
pedal is fully depressed
Misalignment of release levers
Excessive warping of driven disks
Blocking of driven disk hub on trans-
mission shaft splines
Damaged transmission shaft support
bearing in the flywheel
Troubleshooting
Adjust the clearance as specified in clause
5.4.2.12 "Operation 31. Check / adjustment of
clutch control"
Detect and eliminate the cause of failure, per-
forming the operations indicated for trouble-
shooting "Clutch lever 35 (figure 5.4.21 and
5.4.22) fails to return to its initial position while
releasing the clutch pedal"
Change facings or driven disks assembled
Detect and eliminate the cause of oil ingress
into the dry compartment
Change compression springs
Adjust the clearance between the clutch re-
lease bearing and release lever according to
clause 5.4.2.12 "Operation 31. Check / ad-
justment of clutch control"
Ensure the clutch lever full travel performing
the operations specified for troubleshooting
"Clutch lever 35 (figures 5.4.21 and 5.4.22) full
travel is not provided"
Adjust the position of release levers
Replace driven disks
Condition the surface of splines by grinding
ensuring free movement of disks on the
transmission shaft
Replace the transmission shaft support bear-
