Skoda Felicia

1. Remove a head of cylinders, a chain and asterisks of drive ГРМ (the Part Repair without extraction from the car of the petrol engine of the present Chapter of 1.3 l see). Fix sleeves of cylinders.
2. Remove from a cranked shaft of a cover of the bottom heads of rods. In case of need remove шатунные assemblages (see Has undressed Removal, check of a condition and installation of shatunno-piston assemblages).
3. Before to start extraction of a cranked shaft, execute following actions:

a) Temporarily put on a shaft pin an external persistent washer (flutes маслотоков outside from a bearing cover), combine a lock tag with a groove on a cover and plant a washer against the stop in the nest. Make sure that the tag of an internal persistent washer also enters into a reciprocal groove in the cover;
b) Having established a persistent washer, put on the big remote plug (oblique internal edge to the block), an adjusting washer, segment шпонку (the oblique party inside) and an asterisk газораспределительной chains;
c) Establish a pulley of a cranked shaft, screw a pulley bolt (do not forget about a washer) and tighten it with demanded effort, having taken corresponding measures against проворачивания a shaft (see Has undressed Removal, check of a condition and flywheel installation). We will notice that wrong installation of persistent washers will lead to jamming of a shaft in the course of a tightening of a bolt of a pulley. As a result of such jamming washers can easily appear are damaged.

4. With the help циферблатного a measuring instrument плунжерного type measure axial люфт a cranked shaft. Fix a measuring instrument so that it плунжер rested against an end face of a forward pin of a shaft, and axes of the last settled down in parallel. Shift a shaft against the stop back, null the device, then push a shaft forward for all length of its course and consider the measuring instrument indication. Compare result to requirements of Specifications. The size axial люфта is regulated by selection of a persistent washer.

5. Alternatively axial люфт a shaft can be measured with the help probeа лезвийного type. Shift a shaft till the end of its course towards a flywheel, then probeом measure a thickness of a backlash between a cheek of the first crank and a persistent washer.

6. Remove all temporarily established components. Also remove a flywheel (see Has undressed Removal, check of a condition and installation a flywheel).

7. Turn out fixing screws and remove from a pin of a shaft assemblage of a casing of a back epiploon. Remove a casing lining (if that is provided). At assemblage the lining is subject replacements without fail.

8. Check up covers of radical bearings on presence of identification marks. Usually marks are presented by labels in the form of figures with 1 on 3, considering from outside a pulley. If marks are absent, put it independently (take advantage кернером as did it at marks шатунных covers). Besides number of a cover the arrangement of labels should specify an adjusting direction of covers unequivocally.

9. Turn out fixing bolts and remove covers of radical bearings together with loose leaves.
10. Take a cranked shaft and remove from its right pin a persistent washer. Try to remember adjusting position of a washer.
11. Take from the beds the top loose leaves of radical bearings and combine them together with bottom, as installation on the engine.

1. According to the instructions resulted in the Part Repair without extraction from the car of the petrol engine of 1.6 l or Repair without extraction from the car of the diesel engine of the present Chapter execute following procedures:

a) Remove from a cranked shaft a cogwheel of a belt drive of drive ГРМ;
b) Remove components of assemblage of coupling and a flywheel;
c) Remove the pallet картера, маслоотражатель (if it is provided) and the oil pump with маслозаборником;
d) Remove assemblages of casings of forward and back epiploons.
2. In case of need remove pistons with rods (see Has undressed Removal, check of a condition and installation of shatunno-piston assemblages).

3. Operating in the manner similar of 1.3 l described for the engine, measure size axial люфта a cranked shaft. The size axial люфта is regulated by selection of a thickness of persistent washers.

4. Alternatively люфт it is possible to define with the help probeа лезвийного type, having measured by it the maximum size of a backlash between a cheek of 2nd crank and a persistent washer. Compare the received result to requirements of Specifications.

5. Check up covers of radical bearings on presence of factory marks. Digital labels are put as an arrangement of covers in a direction from drive ГРМ to a flywheel.

6. In stages (on 1/4 turns for the approach) ослабьте bolts of fastening of covers, then turn out them manually. Slightly обстучав a hammer with soft brisk, remove covers together and loose leaves. Attach loose leaves to the covers an adhesive tape.

7. Cautiously take a cranked shaft. Try not to admit loss of the top loose leaves of radical bearings. As the shaft weighs much enough, it will be reasonable to resort to the help of the assistant. Lay the removed shaft on an equal working surface, having propped up its wooden wedges.

8. Take the top loose leaves and combine them together with bottom as installation on the engine. Remove 3rd crank established from both parties persistent washers.
9. Pay attention to the dredging pierced in covers and the block - the given dredging are provided for hit in them of ledges of loose leaves and define unambiguity of installation of the last.

1. Carefully wash out a cranked shaft solvent and dry it. Wash out apertures маслотоков and make sure of passableness of the last (take advantage of a special brush). In order to avoid damage of new loose leaves remove facets from edges of apertures.
2. Check up a condition radical and шатунных shaft necks. In case of revealing of signs of non-uniform deterioration, задиров, cracks, cavities and other damages, it is necessary to give a shaft in проточку with the subsequent replacement of bearings with the repair.

3. By means of a micrometer measure diameters radical and шатунных shaft necks. By measurement of diameter in various points of necks, check up the last on presence of signs of ovality or конусности. Compare results of check to requirements of Specifications, in case of need give a shaft in проточку.

4. Check up a condition of surfaces of both pins of a shaft contacting to epiploons. In case of revealing задиров, roughnesses and the other damages, capable to lead to failure of a new epiploon, it is necessary to address for the help to experts of car-care centre where corresponding regenerative repair of pins can be executed.
5. With the help циферблатного a measuring instrument плунжерного type define size of lateral palpation of a cranked shaft in its average part. The shaft should be laid in V-shaped blocks. Try not to damage during performance of check of a surface of necks and shaft pins. The maximum admissible value of lateral palpation of a cranked shaft is not stipulated by manufacturers, however composers of the present Management recommend to accept as a starting point size of 0.05 mm. At excess of the given value it is necessary to replace a shaft, or to deliver for regenerative repair in a car-care centre workshop.

6. On engines of 1.3 l it is necessary to define a micrometer a thickness of persistent washers. The worn out washers are replaced in steam from among corresponding to them on dimensional group. If the shaft was exposed проточке, one of washers after selection can refuse more thickly another, also should establish from the inside (closely to a crank cheek).

7. The description of procedures of check of a condition of loose leaves radical and шатунных bearings see in Section Check of a condition and selection of loose leaves radical and шатунных bearings of a cranked shaft.
