Removal and installation

1. Lift car redock.
2. Remove an intensifying beam, exhaust pipes and tank guards. On a part of cars to a beam the socket of the gauge of oxygen fastens. At removal of a beam do not damage gauge conducting. On late models from a check point of type 4 НР 22 establish on a check point a prop.
3. Turn away a collar holder шлицевого connections on some turns.
4. Designate mutual position of a flange and elastic муфты a check point and flange shaft карданного a shaft.
5. Turn away a nut and bolts of fastening of a shaft from outside a check point, but a shaft do not separate.
6. Turn away a nut and bolts of fastening of a shaft from outside a reducer of a back axis.
7. Having propped up a shaft, turn away 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.

The prevention

On models with гасителем fluctuations turn гаситель approximately on 60 and get from on a check point flange.

9. At removal of a shaft of sliding connection for clearing and greasing put labels of mutual orientation. If labels are not put for any reason at assemblage сориентируйте a shaft so that position карданных hinges coincided. If after assemblage the strong disbalance (occurrence of vibrations) repeat dismantling is found out 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 outside a check point, and then – on a reducer flange. Replace самоподжимные nuts of fastening of a shaft on a reducer flange. Grease aligning details of a shaft молибденовой with greasing. Keep in mind that in connections карданного a shaft different bolts (the bolt class is stamped on a head) which tighten with the specified 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 position in which the bearing is completely unloaded and tighten bolts of fastening of a support with the set moment.
