During the work of coupling dust with the content of asbestos, unhealthy therefore when cleaning coupling do not use compressed air is formed and do not inhale dust. Clear details of coupling of dust with use of means for cleaning of brakes or methyl alcohol, and then wipe dry.
You make removal of the conducted clutch plate as follows:
Remove the working cylinder of coupling and fix by a soft wire on a body, without disconnecting from it a tube.
Remove the transmission. The fork and the bearing of switching off of coupling can remain established on the transmission.
To support a clutch plate in the course of removal, establish a special mandrel or an old main shaft of the transmission in a disk nave.
Note a marker or paint the provision of coupling assembled in relation to a flywheel.
Using the special tool or the screw-driver, for teeths of a gear wreath of a flywheel block it from a provorachivaniye.
Gradually on diagonal weaken coupling fastening bolts assembled, turning each bolt half way until it is terminated springs and bolts can be turned off manually.
Remove press a disk.
Remove the conducted clutch plate together with a special mandrel.
You make check of a condition of the conducted clutch plate as follows:
Check a condition of a surface of friction of a flywheel for lack of cracks, a prigar and wear of a surface.
Check a flywheel beating for what:
Fig. 8.3. Measurement of a beating of a flywheel
– establish on the block of cylinders of the engine an arm with the indicator of hour type so that the measuring tip of the indicator rested against an end face of a flywheel
– install the indicator on 0;
– turn a bent shaft of the engine and record the maximum and minimum values on the indicator;
– the difference between these values makes a flywheel beating which has to be no more than 0,1 mm.
Check a condition of frictional overlays of the conducted clutch plate and in the presence traces of oil or mechanical damages replace the conducted disk with them.
Check thickness of overlays of the conducted clutch plate which have to act over heads of rivets not less than on 0,8 mm. If their thickness of less admissible or if heads of rivets are close to a working surface, replace them or the conducted clutch plate.
Fig. 8.4. Places of check of the conducted clutch plate: 1 – vents in a nave; 2 – thickness of slips; 3 – rivets; 4 – springs
Check that springs were not broken and on them there were no cracks. Check a condition of shlits in a clutch plate nave for lack of wear
The conducted clutch plate has to slide easily and smoothly on vents of a main shaft of the transmission. If replacement of the conducted clutch plate is made, it is also necessary to replace the coupling switching off bearing.
Check a condition of the release bearing. The faulty bearing of switching off of coupling can be defined, without removing it from the car for what during the operation of the engine press a coupling pedal. If when pressing a pedal of coupling noise appears, so the bearing of switching off of coupling is faulty, and it needs to be replaced.
Check a condition of a press clutch plate.
Check reliability of spring connection between a press disk and a casing of coupling. Scratches, absence or damage of rivets are not allowed.
Check press a disk for lack of cracks, a prigar and wear of a surface.
You make installation of the conducted clutch plate as follows:
At installation of the new conducted or press clutch plate remove from them anticorrosive protection.
At installation of the conducted disk you watch that on its frictional slips even in insignificant quantities oil did not get. Therefore before installation by pure rags wipe a privalochny surface of a flywheel and a surface of a press disk. Establish the conducted disk by clean hands.
Grease vents in a nave of the conducted disk with a thin layer of special lubricant on the basis of a molybdenum disulfide.
Fig. 8.5. The provision of installation of the conducted clutch plate (the arrow specifies to a flywheel)
Establish the conducted disk with the aligning mandrel on a flywheel so that the acting part of a nave of a disk with springs was directed outside, to the transmission
Establish coupling assembled, combining openings in a casing of coupling with the directing flywheel pins. At repeated installation of earlier removed press clutch plate check that the tags put before removal were combined.
Fig. 8.6. Sequence of an inhaling of bolts of fastening of a casing of coupling
Gradually in the sequence shown in
the figure 8.6
tighten bolts of fastening of a casing of coupling the moment of 19 N · m.
Take a mandrel from the conducted disk.
Grease a shlitsevy part of a main shaft of the transmission and the directing plug of the bearing of switching off of coupling with a thin layer of special lubricant on the basis of a molybdenum disulfide.
Install the coupling switching off bearing.
Install the transmission.
Install the working cylinder of coupling.
