6.1.1. Possible malfunctions of coupling and ways of their elimination
|
Possible malfunctions of coupling and ways of their elimination
|
|
|
Cause of defect
|
Way of elimination
|
|
Incomplete switching off of coupling - coupling <conducts> (transfers do not join or join hardly)
|
|
|
During the operation of the engine on single turns, the secondary shaft of the transmission included direct transfer and the switched-off coupling should not rotate
|
For conducting check it is necessary to remove cardan transfer and to insert into a back case of the transmission the separate sliding fork of cardan transfer for prevention of a leak of oil
|
|
Availability of air in the hydraulic drive of coupling
|
To pump over hydraulic system of the drive of coupling, to be convinced that movement of the end of a fork - not less than 14 mm
|
|
Jamming of a nave of the conducted disk on vents of a main shaft
|
To eliminate jamming on vents (to smooth out vents)
|
|
Buckling of the conducted disk
|
To replace the conducted disk or to correct it
|
|
Non-simultaneous pressing of the bearing of switching off of coupling coupling switching off levers
|
To adjust a relative positioning of the ends of levers of switching off of coupling
|
|
Incomplete inclusion of coupling - coupling slips (the specific smell is felt, dispersal of the car worsens, the speed of the movement falls, rise is hardly overcome)
|
|
|
Easing press a pruzhinzamaslivaniye of frictional overlays of the conducted disk
|
To replace springs to novymizamenit the conducted disk or frictional slips. In case of small oiling to wash out a surface of slips kerosene and to smooth out a small skin
|
|
Excessive wear of frictional slips (to rivets), working surfaces of a flywheel and a press disk
|
To replace frictional slips or conducted to diskzamenit a flywheel or press a disk or to eliminate on them teases and ring risks with machining taking into account recommendations (see <coupling repair> and <repair of the engine>)
|
|
The compensation opening of the main cylinder because of swelling of a cuff is littered or blocked by a cuff edge
|
To wash out working liquid the main cylinder or to replace a cuff
|
|
Not smooth inclusion of coupling
|
|
|
Oiling of frictional overlays of the conducted disk
|
To replace frictional slips
|
|
Wear of frictional slips (to rivets)
|
To replace the conducted disk or frictional slips
|
|
Jamming of a nave of the conducted disk on vents of a main shaft of the transmission
|
To eliminate jamming on vents
|
|
Non-simultaneous pressing of the bearing of switching off of coupling levers
|
To adjust a relative positioning of levers
|
|
Loss of elasticity of lamellar springs of the conducted disk
|
To replace the conducted disk
|
|
Jamming of levers of switching off of coupling in support or ledges of a press disk in casing windows
|
To eliminate jamming (to smooth out the interfaced surfaces)
|
|
Vibrations and noise in transmission at the movement
|
|
|
Breakage or wear of details of the damping device of the conducted disk
|
To replace the conducted disk assembled
|
|
Wear of a frictional washer or weakening of a press spring of a frictional quencher
|
To replace a frictional washer or a spring of a quencher
|
|
<Peep> and noise in coupling at the working engine
|
|
|
Failure of the bearing of switching off of coupling
|
To replace the bearing. To check and restore coaxiality of a case of coupling and a bent shaft (see <repair of the engine>)
|
|
Scratch when pressing a coupling pedal at the idle engine
|
|
|
There is no lubricant or plastic plugs of an axis of a pedal of coupling wore out
|
To grease plastic plugs with colloidal and graphitic medicine (OST 08-420-74) or to replace worn-out plugs new
|
|
Switching off of coupling happens only by sharp pressing a pedal. By smooth pressing the pedal easily reaches against the stop, coupling is not switched off
|
|
|
Pollution or big wear of a mirror of the main cylinder. Big wear of a cuff of the piston of the main cylinder
|
To wash out, and at wear to replace the main cylinder.
To replace a cuff
|
|
Lowering of the level of liquid in a tank of the main cylinder of switching off of coupling
|
|
|
Wear or hardening of a cuff of the piston of the working cylinder - liquid dribble
|
To replace a cuff
|
|
Violation of tightness of connection of the pipeline with the main and working cylinders - liquid dribble
|
To tighten connecting nuts
