GENERAL INFORMATION

The coupling pedal easily is pressed or fails

• Low level of liquid in system of a hydraulic drive of coupling.
• Damage of the vyzhimny bearing or fork of switching off of coupling.
• The diafragmenny spring of a press disk of coupling is damaged.

Incomplete switching off of coupling (coupling conducts)

• Too high level of liquid in hydraulic system of coupling.
• Jamming of a conducted disk of coupling on shlitsa of primary shaft.
• Buckling of a disk of coupling.
• The knot of a press disk is incorrectly accurate.
• The mechanism of switching off of coupling is worn-out or incorrectly collected.

Incomplete inclusion of coupling (coupling slips)

• Wear of overlays of a disk of coupling is lower than an admissible limit.
• Pollution of overlays of a disk of coupling by oil or lubricant.
• The disk is faulty press or the diafragmenny spring weakened.

Breakthroughs at coupling work

• Wear of overlays of a disk of coupling is lower than an admissible limit.
• Pollution of overlays of a disk of coupling by oil or lubricant.
• The disk or a diafragmenny spring is deformed press.
• Transmission fastenings to the engine are weakened.
• The nave of a disk of coupling or a shlitsa of an entrance shaft of a transmission is worn-out.

Noise by pressing or an otpuskaniye of a pedal of coupling

• The bearing is worn-out vyzhimny.
• Are worn-out or is absent greasing on plugs of a pedal of coupling.
• The knot of a press disk is faulty.
• Damage of a diafragmenny spring of a press disk.
• Damage of dempfiruyushchy springs to a coupling disk.
