Removal, check of a condition and installation of components of coupling

The dust developed in the course of functioning of coupling and accumulating on a surface of its components can contain unhealthy asbestos. AT ALL do not blow off a dust from coupling components the compressed air and do not inhale it. Do not use for removal of a dust by solvents on an oil basis or gasoline. For dust washing off in the prepared capacity it is necessary to use the structures intended for cleaning of brake mechanisms. After end of cleaning and rubbing of components of coupling merge the used cleaner and combine dirty rags in the container marked in appropriate way.

Removal

 PERFORMANCE ORDER

  1. For providing of access to components of coupling it is enough to remove a transmission (РКПП), having left the engine in the car. If the engine is removed for major repairs carrying out, survey and replacement of the worn out components of coupling should be made without fail. Rather small cost of components of coupling in comparison with expenses of time and forces for providing of access to them does reasonable product of replacement of components each time at their removal if it is final they are not absolutely new and are in an excellent condition. The description offered below procedures is made proceeding from the assumption that the engine is not removed from the car.
  2. Disconnect the executive cylinder from the coupling case (Has undressed Removal and installation of components of hydraulic system of deenergizing of coupling).

Do not disconnect a hydraulic line from the executive cylinder - the system is not subject to prorolling in case of hit in it of air!

  1. Remove from car RKPP (the Head the Manual box of a gear change). The engine leave propped up. It is preferable even to hang out it on лебедке. If the engine is propped up by a jack, do not forget to lay for loading distribution between a head of a jack and the pallet картера wooden брусок.

Маслозаборник the oil pump it is located very close to a pallet bottom картера. If the pallet is will drive, it can lead to infringement of functioning of lubricant system.

  1. For поддерживания a conducted disk in the course of removal establish on a nave of a disk the tool for its centering.
  2. Carefully check up a basket of coupling and a flywheel on presence of identification labels. Usually it is labels in the form of letters Х or About, or it is simple dabs put by a white paint. If it is not possible to find a label, put down them with own hand so that at assemblage relative position of a flywheel and a basket has appeared is kept.
  1. Mark position of a basket of coupling concerning a flywheel (marksman) (in a case certainly if be not going to change a basket).
  1. Turning each of bolts of fastening of a basket to a flywheel gradually for one approach, ослабьте them. Operate in a diagonal order, achieving full removal of the loading created by petals диафрагменной of a spring. Then, strong keeping a basket, definitively remove bolts of its fastening. Remove a basket and a conducted disk.

Condition check

Usually refusals and malfunctions of coupling are connected with deterioration of its conducted disk. However, it is necessary to check up a condition of all components of assemblage.

 PERFORMANCE ORDER

  1. Check up a flywheel on presence of cracks, furrows, signs of an overheat and other obvious defects. If defects are insignificant, the flywheel surface can be restored a way станочной processings which composers of the given management recommend to make without dependence from an external condition of a surface of a flywheel. Procedures of removal and flywheel installation are considered in Head Rjadnyj the six-cylinder engine.
  1. Check up a flywheel surface on presence of cracks, overheat signs (sites with the changed colouring) and other obvious defects; flywheel machining in a car-care centre workshop will help to get rid of all insignificant defects - the surface of the flywheel shown in a picture is practically in perfect tune; however, composers of the given Management recommend to make станочную flywheel processing without dependence from its external condition.
  1. Check up a condition of a frictional overlay of a conducted disk. The overlay should tower over heads of rivets a minimum on 1,6 mm. Check up a disk on easing of rivets, presence of deformations, the cracks, the broken springs and other damages. As already it was mentioned above, it is necessary to replace a disk in the presence of the slightest doubts in definition of its condition.

Conducted disk

1 — the Frictional overlay - Are subject to deterioration in the course of coupling functioning
2 — Rivets - Serve for fastening of an overlay and, at contact to surfaces of a flywheel or a press disk cause their damage
3 — Labels - «FLYWHEEL SIDE», or something something like that

  1. Check up a condition of the processed surfaces and petals диафрагменной springs of assemblage of a basket of coupling with a press disk. If the surface is covered by furrows or otherwise damaged, replace assemblage. Also check up a basket on presence of signs of obvious damages, deformations and cracks. Easy polishing of a press disk can be eliminated by means of an emery paper. For assemblage replacement use new or фабрично the restored blocks.
  1. In case of detection of signs of excessive deterioration replace a basket of coupling with a press disk.
  1. Check up a condition выжимного the bearing (Has undressed Removal, check of a condition and installation выжимного the coupling bearing).
  2. Examine directing bearing (Section Check of a condition and replacement of the directing bearing).

Installation

 PERFORMANCE ORDER

  1. Before installation wipe the processed surfaces of a flywheel and a basket of coupling by the rags moistened in acetone. It is important, that on these surfaces or on overlays of a conducted disk oil or greasing have not got. Touch components only with clean hands.
  2. Put a conducted disk and a coupling basket to a flywheel and press them by means of the centering tool. Make sure of correctness of installation of components (the majority of replaceable disks of coupling (conducted) are equipped by marks «FLYWHEEL SIDE» (the party turned to a flywheel) or another of the same sense - if marks are absent, establish a disk демпферными springs to a transmission).
  1. Before tightening fixing bolts отцентруйте a conducted disk in a basket of coupling by means of the special tool - the centering tool can be got in any shop of automobile accessories and its application allows to reduce essentially time for centering of coupling and completely to eliminate any doubts in its correctness.
  1. Moving on basket perimetre, by hand tighten bolts of its fastening to a flywheel.
  2. Having passed the extension piece of the centering tool through equipped шлицами a nave in directing bearing of a cranked shaft, отцентруйте a conducted disk. For full landing of the tool in directing bearing shake it upwards-downwards or here and there. In order to avoid basket deformation, operating in a diagonal order and gradually for each approach, tighten bolts of fastening of a basket to a flywheel with demanded effort. Remove the centering tool.
  3. With high-temperature greasing grease an internal flute выжимного the bearing (Has undressed Removal, check of a condition and installation выжимного the coupling bearing). Also grease contact surfaces of the lever of deenergizing of coupling and the holder of the bearing of a primary shaft of a transmission.
  4. Establish into place выжимной the bearing (Has undressed Removal, check of a condition and installation выжимного the coupling bearing).
  5. Establish into place a transmission (the Head the Manual box of a gear change).
  6. Establish the executive cylinder (Has undressed Removal and installation of components of hydraulic system of deenergizing of coupling).
  7. Clean jacks and lower the car on the earth.
  8. Spend trial runs, having checked up serviceability of functioning of a transmission and coupling.
