Removal and installation

PERFORMANCE ORDER
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.
