Removal, check of a state and installation of assembly of coupling
|
Remember that the dust produced in the course of wear of frictional slips may contain extremely unhealthy asbestos of the person! Do not blow off dust compressed air at all. Do not use for washing of components of coupling solvents on an oil basis - apply only a special cleaner to brake mechanisms or pure methyl alcohol. The used protirochny rags should be put in hermetically closed capacity.
In spite of the fact that some new frictional materials do not contain asbestos, during performing procedures of service of coupling it is necessary to make an assumption that asbestos in them nevertheless is available. |
REMOVAL
|
1. If the power unit is not removed from the car and not dismembered, access to assembly of coupling can is provided by dismantle of the transmission.
|
2. Before starting coupling dismantling, mark the landing provision of a basket of coupling on a flywheel with chalk or a marker. |
3. Moving in a diagonal order, in stages (on a half-turn for approach) evenly weaken bolts of fastening of a basket to a flywheel so that the possibility of their reversing manually appeared.
|
4. Having hooked, remove assembly of a basket from the directing pins... |
|
... then remove a frictional disk. Try to remember the correct adjusting provision of a frictional disk. |

Check of a state
|
|
In view of labor input of procedures of removal and installation of assembly it is usually accepted to make replacement of a frictional disk, a basket and the release bearing in a set even if only one of components is worn-out. Strictly speaking, it is reasonable to replace coupling assembly in a preventive order every time at dismantle of a box of transfers/engine. |
1. Remove coupling assembly. 2. Before performance of cleaning of components study the prevention at the beginning of the present Section. Working in well ventilated room, and it is better - in the open air, carefully clear components, having wiped them with the pure rags moistened in a special cleaner for components of brake mechanisms or methyl alcohol. 3. Estimate degree of wear of frictional slips, check them for existence of signs of mechanical damages or traces of oiling. In case of identification of cracks, traces of an overheat, deep scratches, oil spots or other defects the frictional disk is subject to replacement assembled. Manufacturers of cars (Skoda company) does not put forward frictional overlays of a clutch plate, any on extreme thickness. It is considered to be that heads of rivets have to be drowned below a surface of slips not less than on 3 mm. 4. If frictional slips are in working order, estimate degree of wear of shlits of a nave of a disk, check a state and durability of landing of the torsion springs and rivets. In case of detection of defects the disk is subject to replacement. 5. If frictional slips are polluted by oil, check a condition of the left epiploon of a bent shaft. Besides, the joint a case poddonka with the engine block, and also a main shaft of the transmission can be a source of leak of oil. Replace defective sealing components before starting installation of a new frictional disk. 6. Check assembly of a basket for existence of signs of mechanical damages. Shake press a disk, checking durability of landing of rivets. Make sure of lack of traces of an overheat of feedwells of fastening of a press disk to a basket. In case of identification of damages, signs of wear or weakening of the developed effort of a diaphragm spring replace assembly of a basket. 7. Check a condition of contact surfaces of a flywheel and a frictional disk - they have to be absolutely flat, pure and free from cavities, deep scratches and zadir. Minor defects it can be eliminated by processing of a surface with a fine-grained emery paper. In more serious cases replace a defective component. 8. Check freedom of rotation of the release bearing. Estimate a condition of its working surface. In case of detection of deep scratches, cavities, zadir and other damages replace the bearing. |

INSTALLATION
|
1. At assembly make sure of serviceability of a condition of contact surfaces of a frictional disk and flywheel. From new components carefully remove preservative traces. 2. Grease vents of a frictional clutch plate with a thin layer of high-temperature lubricant like Kluber Microlube GL202, GL261 or GL262, or Mobil lithium 932 or 933. Try not to allow hits of lubricant on frictional slips. Remove excess of lubricant. 3. Establish a frictional disk by the sprung party of a nave from a flywheel aside. On some disks the special marking allowing to define by what party to a flywheel it should be established is provided. 4. Establish assembly of a basket of coupling. At installation of an old basket track combination of the landing tags put in the course of dismantle. Screw fixing bolts and tighten them, so far only by hand that there was a possibility of correction of the provision of assembly. 5. Now it is necessary to center a frictional disk that at installation of the transmission of a vent of a pin of a main shaft got to the center of a nave of a disk. 6. For centering pass the screw-driver or other suitable core throughout an opening in an end face of a bent shaft. Now the frictional disk can be centered in relation to a shaft. It is alternatively possible to use the special tool that allows to reduce considerably the time expenditure connected with adjustment. The tool can be manufactured in house conditions of the suitable metal core or wooden whetstone which are densely sitting down in an opening in an end face of a bent shaft. In the place of threading of a core in a nave it is necessary to reel up an adhesive tape on it, having provided landing density in a stupichny opening.
|
7. Having finished centering of a frictional disk, tighten bolts of fastening of a basket with the required effort - act in a diagonal order, you make tightening evenly, in stages. |
8. Establish into place assembly of the transmission (see the Section Removal and installation of the transmission). |
