10.3. Removal, check of a state and installation of components of assembly of coupling

Remember that the dust produced in the course of wear of frictional overlays of the conducted clutch plate may contain noxious to health asbestos. Do not blow off dust compressed air and try not to inhale it. Do not apply to rubbing of components of coupling solvents on an oil basis, - use only special brake cleaners or pure methyl alcohol. Put the used rags before utilization in hermetically closed container.


Removal

 PERFORMANCE ORDER

For the purpose of ensuring access to coupling assembly usually remove the transmission, leaving the engine on the car. If the engine is already removed for performance of the general or capital repairs, the condition of components of coupling has to be checked without fail. Considering rather low cost of details and rather large volume of metalwork works on ensuring access to coupling assembly, it makes sense to make replacement of the last regardless of a condition of its components. The description of the procedure of removal of coupling without extraction of the engine from the car is given below.

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!

2. The car also establish to Poddomkratta it on props.
3. Remove assembly of transmission (see the Head the Manual transmission).

4. Attentively examine surfaces of a flywheel and assembly of a basket of coupling on marking existence (usually in the form of the letters of X or O put with white paint). If it is not possible to find marking, put it independently, having unambiguously marked the provision of a basket concerning a flywheel.

5. Working in a diagonal order, in stages (on 1/4 turns for approach) evenly weaken bolts of fastening of a basket of coupling to a flywheel, having completely unloaded a diaphragm spring. Reliably supporting assembly, finally turn out bolts, then separate a basket from a flywheel and remove knot from the car.

6. Release a clamp and remove assembly of the release bearing.

It is not necessary to use solvent for washing of the release bearing!

7. Estimate a condition of a fork of switching off of coupling and its basic surfaces. In case of need remove a fork and turn out its spherical support from a transmission case.
8. Attentively check a condition of all removed components (see further), replace the worn-out and damaged knots.


Check

 PERFORMANCE ORDER

1. Most often violation of serviceability of functioning of coupling is accompanied by wear of frictional overlays of the conducted disk. Nevertheless, it is necessary to study also attentively a condition of all other components of assembly.

If at a surface of components of assembly there are oil traces (sites, zapolirovanny to gloss), it is necessary to reveal and remove the leak cause, - check a condition of a back epiploon of a bent shaft and an epiploon of a main shaft of the transmission, in case of need replace defective components.

2. Examine a working surface of a flywheel on existence of signs of deformation of cracks, traces of an overheat, furrows and other damages. Insignificant defects can be eliminated by a pro-point in the conditions of a workshop of car service (the pro-point is recommended to be made regardless of a condition of a surface). The description of procedures of removal and installation of a flywheel is provided in the Section Removal and installation of a flywheel / a driving disk.

3. Check a condition of the directing bearing (see the Section Check of a State and Replacement of the Directing Bearing).

4. Estimate degree of wear of frictional overlays of the conducted clutch plate. The surface of slips has to tower over heads of rivets at least on 0.8 mm. Make sure of density of landing of all rivets, check the torsion springs / dampers for existence of cracks, traces of deformation and other mechanical damages. As it was already mentioned above, replacement of components of coupling it is reasonable to make every time at assembly dismantle therefore pay attention to the slightest errors.

5. Together with the conducted disk it is always replaced as well the release bearing.
6. Estimate a condition of the processed surfaces of a press disk and petals of a diaphragm spring. At detection of defects replace assembly of a basket. Traces of easy polishing can be removed by means of a fine-grained emery paper. Through company car repair shops of the Mitsubishi company it is always possible to get the restored coupling assembly on an exchange basis.


Installation

 PERFORMANCE ORDER

1. Establish on regular a spherical support of a fork of switching off of coupling and tighten it with the required effort (35 H • м).
2. Establish a coupling switching off fork.
3. Grease with universal lubricant basic and contact surfaces of a fork.
4. At the corresponding complete set grease with the same lubricant a pusher of the executive cylinder of coupling and its reception nest in a switching off fork.
5. Fill refractory lubricant in an internal flute of the release bearing, - try not to allow hits of lubricant on nonmetallic elements of assembly.
6. Install the bearing on the regular place and fix it by a clamp.
7. Before installation wipe the surfaces of a flywheel and a press disk which were exposed to machining with the rags moistened in acetone. It is extremely important to achieve full degreasing of working surfaces of components, as well as frictional overlays of the conducted disk. Touch components with only purely washed up hands.

8. Press assembly of a basket (with the enclosed and fixed tool for centering of components the conducted disk) to a flywheel. Track that the clutch plate was developed to a flywheel by the marked corresponding marking (Flywheel side type) by the party. If marking is absent, remember that the conducted disk is always established by the torsion springs / dampers to the transmission.

9. By hand tighten bolts of fastening of assembly to a flywheel, - before a vvorachivaniye a carving part of fixture should be greased with the fixing sealant.

10. Make centering of components of assembly of coupling. The special tool is passed through a nave of the conducted disk and refuels in the directing bearing in an end face of a pin of a bent shaft. For alignment of components move the tool in different directions in the vertical and horizontal planes.

11. In a diagonal order in stages densely tighten assembly fastening bolts, then hold on them with the required effort (19 H • м: the Galant 1994 ÷ models of 1998 of the issue and 22 H • м: other models). Take the tool for centering of components of coupling.

12. Install the transmission and all components which were removed for the purpose of ensuring access. Track that all fixture was tightened with the required effort.
13. Check serviceability of functioning of coupling.
