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

Assembly of the conducted clutch plate

1 — Frictional slips - in a picture are worn-out below an admissible limit
2 — Rivets - are used for fastening of frictional slips and at excessive wear of the last begin to leave furrows on a working surface of a flywheel
3 — the Torsion springs or dampers - have to be checked for existence of cracks and signs of deformation

4 — the nave Equipped with vents - has to slide freely on vents of a main shaft of the transmission,
vents should not be excessively worn-out
5 — Marking of the party of a disk turned to a flywheel - usually in the form of a "Flywheel side" inscription


 PERFORMANCE ORDER

1. 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.
2. Remove a gear shifting box (see Removal and the RKPP installation). Prop up the engine a jack, or hang out it from above on the winch (the last is preferable). In case of use of a jack do not forget to lay between its head and the pallet of a case wooden whetstone for the purpose of distribution of loading.

 Maslozabornik of the oil pump settles down very close to the bottom of the pallet of a case and can be easily damaged at deformation of the last!

3. The fork of switching off of coupling and the release bearing can be left on the regular places, however not their state should be checked also (see the Section Removal, check of a state and installation of the release bearing and lever of switching off of coupling).
4. In order to avoid loss of the conducted disk at removal of a basket, pass the tool intended for coupling centering throughout its nave.

5. 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 /

6. Working in a diagonal order, in stages evenly weaken bolts of fastening of a basket of coupling to a flywheel, having completely unloaded a diaphragm spring.

7. Reliably supporting coupling assembly, finally turn out bolts, then separate a basket from a flywheel and remove knot from the car.

CHECK

 PERFORMANCE ORDER

1. Most often violation of serviceability of functioning of coupling is connected with wear of frictional overlays of the conducted disk. Nevertheless, it is necessary to study attentively a condition of all other components of assembly.
2. Examine a working surface of a flywheel on existence 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 appropriate section of the Head Dvigatel.
3. 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 1.6 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.
4. Together with the conducted disk it is always replaced as well the release bearing (see the Section Removal, check of a state and installation of the release bearing and lever of switching off of coupling).
5. Estimate a condition of the processed surfaces and petals of a diaphragm spring of a press disk. 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 Honda company it is always possible to get the restored coupling assembly on an exchange basis.

INSTALLATION

 PERFORMANCE ORDER

1. 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.

2. Press assembly of a basket (with the tool enclosed in it and fixed for centering of components by 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.

3. By hand tighten bolts of fastening of assembly to a flywheel.
4. Make centering of components of assembly of coupling. The special tool is passed through a nave of the conducted disk and refuels in a pocket 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. Working in a diagonal order, in stages densely tighten assembly fastening bolts, then hold on them with the required effort. Take the tool for coupling centering.
5. Refractory lubricant fill an internal flute of the release bearing (see the Section Removal, check of a state and installation of the release bearing and lever of switching off of coupling). Also grease the contact surfaces of the lever of switching off of coupling and a pin of a main shaft of the transmission.
6. Install into place the release bearing (see the Section Removal, check of a state and installation of the release bearing and lever of switching off of coupling).
7. Install the transmission and all components which were removed for the purpose of ensuring access. Track that all fixture was tightened with the corresponding effort.
