2.1 PROPELLER AND SHAFTING
2.1.1 TYPE OF DELIVERY
The propeller hub is delivered assembled and mounted on the tail shaft, the piston rod, piston
rod head, blocks and blade roots are in position. If it is possible, due to transport reasons the
blades are mounted on the propeller hub. If not the blades are mounted on the hub before
installation, see below.
2.1.2 INSTALLATION OF BLADE
Refer to the exploded view overleaf.
• The blades can be mounted before that the propeller shaft is installed.
• If the shaft is installed in the ship before mounting of the blades. The blades are then
fitted in turn in the upright position. The same procedure is carried out for each propeller
blade.
NOTE: After the final tightening of the blade screws, the hub shall be tested to ensure that
there is no leakage at blade screws, blade seals and oil plugs. For example with air of low
pressure.

2.1.3 INSTALLATION OF PROPELLER SHAFT
Proceed as follows:
1. Thoroughly clean the tailshaft and sterntube, carry out a complete inspection for damage
that might have occurred during transportation.
2. Lubricate and protect all parts using thick oil in preparation for installation.
Note: Care must be taken not to damage the surfaces during lifting operations.
3. Mount the outer sterntube seal on the shaft in accordance with the manufacturer's
instructions.
4. Insert the tailshaft into the sterntube.
5. Fit a check unit on the propeller shaft to prevent it from sliding aft.
6. Check the number markings on the blade and hub and the blade and screws. Fit the
correct blade and torque tighten the screws. If it is not possible to torque tighten all bolts
using a torque multiplier, then a rotation measurement can be taken on the first bolt as
follows:
Screw the first bolt in hand tight using the spanner supplied with the propeller. Note the
angle. Continue tighten using a suitable torque multiplier and measure the final angle of
rotation when the correct torque is achieved.
7. When all blades are fitted check for freedom of movement by turning two blades at the
same time.
8. Fit the shaft coupling in accordance with the shaft coupling instructions, see chapter" Oil
pressure coupling type OMC".
9. Fit the inner sterntube seal in accordance with the manufacturer's instructions.
10. Fit and secure the protective casing on the outer sterntube seal.
11. In addition it is advisable to make a check measurement, for example from the front end
of the sterntube to the front end of the shaft, to ensure that no movement has taken
place during launching.
2.1.4 OIL FILLING OF HUB
See separate chapter regarding procedures of filling hydraulic and lubrication oil. The oil can
be filled when the coupling, intermediate shaft (if fitted), gear and OD-box are mounted.

2.1.5 LOCKING OF SCREWS AND PLUGS BEFORE LAUNCHING
Check that all blade screws, shaft flange screws and plugs are locked. Weld the locking pins
onto the bolt heads or plugs using stainless steel electrodes (Berg supplied).
Be sure that the material used is of the stainless steel type.
2.1.6 CHECK OF CORRECT MOUNTING OF BLADE
Find out and be sure of the direction of the propeller shaft. Which edge is the leading edge of
the blade is taken as understood and not described below.
When the propeller is rotated the leading edge goes first. If the blade is correctly mounted,
the pitch through the water during one revolution by the root section of the blade is similar in
length to that for the tip section. See figure below:
If the blade is incorrectly mounted, the pitch through the water during one revolution by the
root section of the blade is very much less than that for the tip section. See figure below:
