INSTALLATION INSTRUCTION
5.8. PROPELLER SHAFT FLANGE
At delivery, the flange to the reversing gear is rough-drilled only. The bores are to be made with utmost accuracy
and have to correspond to the guiding edge on the flange.
Max. admissible radial stop: 0,05 mm
In many cases it is recommended to bore the coupling flange to the reversing gear with the same conicity as for
the propeller. Thus the shaft will be equal on both ends and can, therefore, be turned in case of being worn out
in the stem bearing.
5.9. ENGINE MOUNTS
The flexible engine mounts provide proper insulation between engine and base frame, thus reducing the
noise conveyed to the hull. This engine suspension may also absorb the thrust and shearing forces of the
propeller.
Install the engine mounts directly onto the member of the base frame see ill. 5/3
For an assembly with flexible engine mounts the overall height of the engine mounts is to be considered to
achieve the proper installation height of the engine. Height Adjustment recommended to achieve accurate
alignment of the suspended unit.
When fitting mounts with height adjusters, care must be taken to ensure that excessive bending forces are
not imposed on the center spindle (screw).Mountings fitted with height adjusters are designed to allow a
variation of ± 5 mm on nominal mean height (see illustration 5 mm distance between adjustment nuts). Any
larger variations need to be accommodated by fitting shims or packers under the mounting base. Vertical and
horizontal alignment should then be effected using the height adjusters and slotted holes in the mounting
base. Recheck alignment after fixings are tightened to the specified torque values (nut center spindle screw
110 120 Nm).
