Removal and installation

PERFORMANCE ORDER
1. Lift a car front.
2. Remove an intensifying beam, exhaust pipes and tank guards. On a part of cars to a beam the socket of the sensor of oxygen fastens. At removal of a beam do not damage sensor conducting. On late models from a check point of NR 22 type 4 establish on a check point a prop.
3. Unscrew a holder of a collar of shlitsevy connection on some turns.
4. Designate the mutual provision of a flange and the elastic coupling of a shaft of a check point and a driveshaft flange.
5. Unscrew nuts and bolts of fastening of a shaft from a check point, but a shaft do not separate.
6. Unscrew nuts and bolts of fastening of a shaft from a reducer of a back axis.
7. Having propped up a shaft, unscrew bolts of an average support.
8. Bend a shaft about an average support and remove from an aligning ledge on a check point flange. For expansion of working space it is recommended to pull together with shaft for a shaft of sliding connection, thus section of a shaft do not disunite.

Prevention

On models with a quencher of fluctuations turn a quencher approximately on 60 ° and get from on a check point flange.


9. At removal of a shaft of sliding connection for cleaning and greasing put labels of mutual orientation. If labels are not put for any reason, at assembly сориентируйте a shaft so that position of kardanny hinges coincided. If after assembly the strong imbalance (emergence of vibrations) is found, repeat dismantling and turn hinges on 180 ° from each other.
10. Installation is carried out upside-down taking into account the following. Combine the labels put at dismantling, and tighten nuts with the set moment. At first fix a shaft from a check point, and then – on a reducer flange. Replace samopodzhimny nuts of fastening of a shaft on a reducer flange. Grease aligning details of a shaft with molybdenic greasing. Keep in mind that in connections of the driveshaft different bolts (the class of a bolt is stamped on a head) which tighten the every moments are used.

11. Create in the bearing of an average support a preliminary axial tightness. For this purpose displace the bearing on 4–6 mm (on shaft with a sliding average support) or on 2–4 mm (on shaft without a sliding average support) from situation in which the bearing is completely unloaded and tighten bolts of fastening of a support with the set moment.
