Center Support: Service and Repair

Support bearing - front
The procedure to replace the rear support bearing is identical to that of the front.

Remove
1. Remove front propeller shaft.
2. Remove rear propeller shaft.





3. Note the fitted position of the support bearing on the viscous coupling.

CAUTION: When removing and refitting any components to viscous unit, full support must be given using the flange adjacent to the splines. Under no circumstances should any load be applied through the viscous unit bearings.





4. Position suitable press bars to support bearing as shown, taking care that the press bars are not positioned on the steel finger.
5. With assistance, position viscous coupling assembly onto press bed.
6. Position LRT-37-011/2 thrust button onto viscous coupling splines.
7. With assistance, press the splined end of the viscous coupling unit through the support bearing. Take care that the viscous coupling does not drop when free of the support bearing.
8. Remove viscous coupling assembly from press.

Refit
1. Clean flinger, bearing journal, splines and support bearings.
2. Ensure that cavities between bearing and outer shrouds are packed with Texaco Novatex EP2 grease.





3. With assistance, position viscous coupling assembly onto press bed and locate the press bars onto collar on viscous coupling as shown.
4. Position LRT-60-010/1 onto bearing inner race, and with assistance, press support bearing onto viscous coupling.
5. Remove viscous coupling assembly from press.
6. Spin support bearing to confirm true running.
7. Fit front propeller shaft.
8. Fit rear propeller shaft.
