Viscous coupling assembly (page 2 of 2)

10. Repeat the procedure and remove the front support bearing from the viscous coupling unit.
11. Remove 3 bolts securing torsional vibration absorber to the viscous coupling unit.
12. Note orientation of torsional vibration absorber on viscous coupling unit.

Refit

NOTE: Replace support bearings if worn or damaged.

1. Ensure mating face of torsional vibration absorber and viscous coupling are clean and free from burrs.
2. Position torsional vibration absorber to viscous coupling, fit and tighten bolts to 80 Nm.
3. Clean flinger, bearing journal, splines and support bearings.
4. Ensure that the cavities between the bearing and outer shrouds are packed with Texaco Novatex EP2 grease.

5. With assistance, position viscous coupling unit onto press bed and locate the press bars onto collar as shown.
6. Position front support bearing onto viscous coupling unit.
7. Position LRT-60-010/1 onto bearing inner race, and with assistance, press support bearing onto viscous coupling unit.
8. Repeat procedure to fit rear support bearing to viscous coupling unit.
9. Spin support bearings and check for true running.
10. Clean mating faces and splines on rear propeller shaft and viscous coupling.
11. Engage splines between propeller shaft and viscous coupling unit shaft and push home propeller shaft as far as possible.
12. Partially fit bolt and new tab washer, position ’U’ spacer between tab washer and spline yoke.
13. Tighten bolt to to 65 Nm to fully seat splines and secure with tab washer.
14. Fit front propeller shaft. See this section.
