Viscous coupling assembly (Freelander 1)

Dismantling

1. Remove the front propeller shaft.

2. Remove the rear propeller shaft.

CAUTION: When removing and installing components related to the viscous coupling, the flange on the spline side must be completely suspended. Under no circumstances should the load be transmitted through the bearings of the viscous coupling.

3. Mark the position of the viscous coupling support bearings.



4. Install the support prisms on the press table as shown in the figure, making sure that the prisms do not come into contact with the oil flinger ring.

5. With the help of a partner, install the viscous coupling on the press table.



6. Install the LRT-37-011/2 mandrel onto the splines of the viscous coupling.

7. With the help of a partner, press the splined end of the viscous coupling through the support bearing. Do not allow the coupling to fall once it is free of the support bearing.

8. Remove the viscous coupling from the press table.

Installation

1. Wipe the oil deflector, the shaft journal under the bearing and the support bearings.

2. Check that the cavities between the bearing and the outer housing are filled with Texaco Novatex EP2 grease.



3. Using the help of a partner, install the viscous coupling on the press work table so that the coupling flange rests against the prisms, as shown in the figure.

4. Install the LRT-60-010/1 mandrel onto the inner bearing race and press the bearing onto the viscous coupling.

5. Remove the viscous coupling from the press table.

6. Check the bearing for freedom of rotation.

7. Install the front propeller shaft.

8. Install the rear propeller shaft.
