Remove the belt and unscrew the belt pulley; you will need to hold the propeller
blades in your hand under the model to secure the propeller wheel. Unscrew the
motor and remove the six screws which retain the propeller wheel cover. Fit the
motor screws again, tighten them lightly, and gently tilt the motor in order to remove
the whole power unit; you can now withdraw the motor and cover from the guide
sleeve. At this stage it is possible to replace the bearings in the cover. Once the
bearings are removed, the main control lever and the plain bush can also be
dismantled. Measure the depth at which the plain bush is fitted before removing the
main control lever. The control lever must not
contact the bottom of the propeller wheel.

The propeller wheel is sealed with a cover and five
screws. The propeller blades can be replaced by
removing the cover and the guide sleeve. The
blades are secured in the propeller wheel using
circlips. When removing them note the orientation of
the white sliding blocks between the lever and the
control plate (see illustration).
Re-assemble the unit by reversing the procedure
described above. Don’t forget to fit the M3 x 3 grubscrew.

The malleable gasket material can be re-used an indefinite number of times. First
remove the residue from the installation ring and the cover, then knead the material
together and form it into a cord again. Lay this in the ring and re-install the VSP.
It will not be possible to achieve exactly the same installed position a second time, so
you must always repeat the set-up procedure with the VSP after re-connecting all the
linkages.
Important:
the propeller wheel mechanism is lubricated by water only: do not apply
oil or grease to the propeller wheel, as this will just ruin the plastic.
Oil the linkage balls in the ball-links at regular intervals, but take care that no oil runs
through the guide sleeve into the propeller wheel. The plain bearing can be lubricated
lightly with gearbox grease or high-viscosity oil: apply a little grease between the
guide sleeve and the control lever of the VSP.
Important:
do not use mineral oil.
Installing the Voith Schneider Propeller in the model
A circular 84 mm Ø opening must be cut in the bottom of the hull for each drive unit.
The ABS support ring, which is supplied with each power unit, is glued in this circular
opening. The outrigger which bears the motor must be positioned facing either the
bow or the stern.
Locate the gasket material supplied in the set, mould it into a cord about 1.5 mm in
diameter using your hands, then place it directly in the internal shoulder of the 1.5
mm recess on the sealing surface of the mounting ring; it should be located outside
the six holes. Press the gasket material into the corner of the 1.5 mm recess, and
check that it is not interrupted at any point all round. Place the VSP in the support
ring and secure it using the six screws supplied. Caution: only tighten the screws
moderately. Tighten the screws steadily, working sequentially round the circle; do not
tighten them alternately, from side to side.
