3.1.3. Possible malfunctions, their reasons and methods of elimination

Cause of defect
Elimination method
Incomplete switching off of coupling (coupling "conducts")
1. Insufficiently full speed of a pedal of coupling
1. Adjust the coupling drive
2. A buckling of the conducted disk (a face beating more than 0,5 mm)
2. Correct or replace a disk
3. Jamming of a nave of the conducted disk on vents of a main shaft
3. Clear vents, wash out white spirit. At wear of shliyets replace a main shaft or the conducted disk
4. Distortion or buckling of a press disk
4. Replace a coupling casing assembled with a press disk and a spring
5. Weakening of rivets or breakage of frictional overlays of the conducted disk
5. Replace slips, check a face beating of a disk
6. Damage or jamming of the drive of coupling
6. Remove the causes causing jamming. Replace the damaged details
Incomplete inclusion of coupling (coupling "slips")
1. The increased wear or burning of frictional overlays of the conducted disk
1. Replace frictional slips or the conducted disk assembled
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, replace the worn-out or damaged epiploons of the transmission and engine. Check lack of a leak of oil through bolts of fastening of a flywheel; in the presence of a leak establish bolts on sealant as it is specified in the head "Assembly of the engine"
3. Damage or jamming of the drive of coupling
3. Remove the causes causing jamming. Replace the damaged details
Breakthroughs during the coupling work
1. Oiling of frictional overlays of the conducted disk, surfaces of a flywheel and a press disk
1. Carefully wash out white spirit greasy surfaces, replace the worn-out or damaged epiploons of the transmission and engine. Check lack of a leak of oil through bolts of fastening of a flywheel; in the presence of a leak establish bolts on sealant as it is specified in the head "Assembly of the engine"
2. Jamming in the coupling drive
2. Remove the causes causing jamming. Replace the damaged details
3. Damage of a surface or buckling of a press disk
3. Replace a coupling casing assembled with a press disk
The increased noise at coupling inclusion
Breakage of springs of a damper of the conducted disk
Replace the conducted disk assembled
The increased noise at coupling switching off
Wear, damage, leak of lubricant from the coupling switching off bearing
Replace the bearing
