Installing Viscous Coupling
Check that the flange and viscous coupling mating surfaces are absolutely clean.
Align viscous coupling as marked.
Use new screws. Tighten crosswise in stages until the viscous coupling flange is in full contact. Tighten crosswise to 50 Nm (37 ft.lb.).
If reinstalling the old viscous coupling, continue with installing torque tube.
NOTE; If installing a new viscous coupling, measure according to Measuring flange, viscous coupling and Balancing procedure,See:
Drive/Propeller Shafts, Bearings and Joints After measuring continue installing flange to viscous coupling.
