4.1.5. Possible malfunctions of coupling, their reason and methods of elimination


Cause of defect
Elimination method
Incomplete switching off of coupling (coupling "conducts")
1. The increased gaps in the coupling switching off drive
1. Adjust the coupling switching off drive
2. A buckling of the conducted disk (a face beating more than 0,5 mm)
2. Correct a disk or replace new
3. Roughnesses on surfaces of frictional slips
the conducted disk
3. Smooth out slips a metal brush or replace new
4. Weakening of rivets or breakage of frictional overlays of the conducted disk
4. Replace slips, check a face beating of a disk
5. Jamming of a nave of the conducted disk on vents of a main shaft of the transmission
5. Clear vents, cover with LSTsV15 lubricant.
If the jamming reason smyaty or wear of shliyets, then replace a main shaft or the conducted disk
6. Breakage of the plates connecting a persistent flange to a coupling casing
6. Replace a casing of coupling with a press disk assembled
7. Air in system of a hydraulic actuator
7. Pump over system
8. Leak of liquid from system of a hydraulic actuator through connections or the damaged pipelines
8. Tighten connections, replace the damaged details, pump over system of a hydraulic actuator
9. Leak of liquid from the main cylinder or the cylinder of the drive of switching off of coupling
9. Replace sealing rings, pump over system
10. The opening in a tank cover got littered that caused depression in the main cylinder and an air suction
in the cylinder through consolidations
10. Clean an opening in a tank cover, pump over
system
11. Violation of tightness because of pollution or
wear of a forward sealing ring of the main thing
cylinder
11. Clear a sealing ring, at wear
replace
12. Weakening of rivets of fastening of a press spring
12. Replace a casing of coupling with a press disk assembled
13. Distortion or buckling of a press disk
13. Replace a casing of coupling with a press disk assembled
Incomplete inclusion of coupling (coupling "slips")
1. There are no gaps in the switching off drive
couplings
1. Adjust the coupling switching off drive
2. The increased wear or burning of frictional overlays of the conducted disk
2. Replace frictional slips or the conducted disk assembled
3. Oiling of frictional overlays of conducted
disk, surfaces of a flywheel and press disk
3. Carefully wash out White spirit greasy
surfaces, remove the causes of oiling of disks
4. The compensation opening of the main cylinder is littered
4. Wash out the cylinder and clean a compensation opening
5. Damage or jamming of the drive of coupling
5. Eliminate the malfunctions causing jamming
Breakthroughs during the coupling work
1. Jamming of a nave of the conducted disk on vents
main shaft
1. Clear vents, grease with LSTsV15 lubricant.
If the jamming reason smyaty or wear of shliyets, then if necessary replace a main shaft
or the conducted disk
2. Oiling of frictional overlays of the conducted disk, surfaces of a flywheel and a press disk
2. Carefully wash out White spirit greasy surfaces and remove the cause of oiling of disks
3. Jamming in the switching off drive mechanism
couplings
3. Replace the deformed details.
Remove the causes causing jamming
4. The increased wear of frictional slips
the conducted disk
4. Replace slips new, check,
whether there are no damages of surfaces of disks
5. Weakening of rivets of frictional overlays of the conducted disk
5. Replace faulty rivets, and if necessary - slips
6. Damage of a surface or buckling
press disk
6. Replace a casing of coupling with a press disk
assembled.
The increased noise at coupling switching off
1. Wear, damage or leak of lubricant from the coupling switching off bearing
1. Replace the bearing
2. Wear of the forward bearing of a main shaft of the transmission
2. Replace the bearing
The increased noise at coupling inclusion
1. Breakage or decrease in elasticity of springs of a damper
the conducted disk
1. Replace the conducted disk assembled
2. Breakage, decrease in elasticity or soskakivaniye
ottyazhny spring of a fork of switching off of coupling
2. Replace a spring new or fix
3. Breakage of the plates connecting press a disk
with a casing
3. Replace a casing of coupling with a press disk
assembled
