Greasing replacement in hinges

1. To remove a semi-axis with two hinges.
2. After designation of provision of a semi-axis of rather internal part of the hinge and a metal cover of rather external part of the hinge to take the hinge from a protective casing and to disconnect it from a semi-axis.
3. To clear the hinge and to check degree of wear of balls and directing. To put greasing in the hinge (see fig. Driving hinge): in space (And) 10–15 g and in space (In) 65–70 g in case of a two-layer protective casing and about 85 g – in case of a three-layer protective casing.
4. To establish the hinge on a semi-axis and to fix a protective casing. In case of need it is necessary to put on a new protective casing, paying attention to that greasing did not get in it.
5. To establish a metal casing according to earlier executed designations and to provide its tightness in hinges.
6. To establish a semi-axis.

Consolidation of hinges

In case of greasing performance on a hinge surface from under a metal casing it is necessary to arrive as follows.

1. To remove a semi-axis together with two hinges, previously having designated its situation concerning elements to which it was connected.
2. To take the hinge from a metal casing and to disconnect it from a semi-axis.
3. After careful cleaning of a surface of the hinge and a metal casing to put on A surfaces (see fig. A surface for drawing of pressurizing paste) pressurizing paste.


To apply only not hardening pastes and to put them so that it was possible to tighten bolts evenly.

4. To connect the hinge to a semi-axis and to establish a protective casing.


The driveshaft of the car is connected to secondary shaft of a transmission the elastic hinge. The flange on secondary to a shaft of a transmission is a component of this hinge.

Removal and installation of the elastic hinge

1. Extraction of the elastic hinge demands blocking of bolts with Torx type heads.
2. Before installation of the elastic hinge it is necessary to check, whether bolts with Torx type heads the moment of 80 Nanometers are tightened.


If these bolts are turned, it is necessary to cover their carving with Loctite 270 glue.

3. To put greasing on the washers located on both parties of a flange, so that let's to them be turned in the course of a tightening new (at each installation of the hinge) nuts by the moment of 75 Nanometers.
4. To check a condition of rubber dampers In the elastic hinge (see fig. Elastic hinge).
5. If rubber dampers are erose or have cracks, it is necessary to replace the driveshaft together with the hinge. It is impossible to replace only the hinge as the hinge and a shaft are balanced together.


Small cracks on a forward surface of the hinge yet do not mean obligation of its replacement.

Other information concerning a technical characteristics, adjustment and repair of the driveshaft and the back bridge, is provided in section 7.
