Vetus Uniflex 12 Instructions D'installation page 4

Mounting
In connection with the axial movement of the propeller shaft a
minimum free space between outer bearing and propeller hub
is required.
Propeller-thrust
N.B. When sailing in forward direction the rubber part must be
compressed.
Using the Uniflex in combination with a V-drive type gearbox is
not allowed!
Over-size (larger) propeller shaft diameter
Reduce the propeller shaft diameter for the taper length (dimen-
sion 'A') to the given dimension 'd' of the coupling, see 'Overall
dimensions'. Radius 'r' minimal 2 mm (0.08").

Misalignment
The maximum allowable
misalignment of the pro-
peller shaft is 2˚.
General assembly
To achieve a reliably operating coupling all the bolts and nuts
must be tightened with the torques given. Use a torque wrench;
tightening it 'in the blind' will not lead to satisfying results.
Grease the outside of the taper and the bolts.
