Malfunction, external manifestation, cause
Troubleshooting
Clutch does not transmit full torque (“skidding")
There is no clearance between the shifter
bearing and the release levers –
“clutch is
half disengaged” (insufficient clutch pedal
free travel)
Adjust the clutch pedal free travel, as de-
scribed in clause
5.4.3.10 "Operation 31.
Check/adjustment of clutch pedal free trav-
el"
Incomplete engagement of clutch (clutch
lever fails to return to its initial position)
when the clutch pedal is released, due to
failure in clutch operation control
Adjust the clutch pedal free travel, as de-
scribed in clause
5.4.3.10 "Operation 31.
Check/adjustment of clutch pedal free trav-
el"
Clutch driven disk linings are worn out
Replace the linings or driven disk assembly
Clutch driven disk linings are oiled-up due
to ingress of oil into dry section
Detect and eliminate the cause of oil in-
gress into dry section
Poor pressure spring force (spring shrinks
due to continuous skidding and clutch
overheating)
Replace the springs
Clutch fails to disengage completely (“clutch grabs and shudders”)
Clearance between clutch shifter bearing
and the release levers is increased (substan-
tial free travel of clutch pedal)
Adjust the clutch pedal free travel, as de-
scribed in clause
5.4.3.10 "Operation 31.
Check/adjustment of clutch pedal free trav-
el"
The release levers are unevenly attached to
the release bearing
Adjust the position of the release levers
Excessive warping of driven disks
Check the face run-out of driven disk linings
in relation to hub spline outer diameter –
the
value shall exceed 0.8mm at a radius of
165mm.If it is impossible to adjust, the disks
shall be replaced
Jamming of driven disk hub on transmission
shaft splines
Skin the splines providing free movement of
disks on the transmission shaft
Transmission shaft support bearing in the
flywheel is damaged
Replace the bearing
Oil in dry section of the clutch body
Wear of the collar, sealing the crankshaft
Replace the collar
The bearing cover of the rear PTO driven
shaft is pushed out when assembling the
repaired tractor
Install a new cover or set the old one right
Shifter bracket collar is worn out
Replace the collar
