Disassembling instructions

It could be necessary for repair or checks to disassemble
the generating set. One can take off the white cover easily
for regular maintenance and inspection. For further repair
or inspection one can take off the upper green part as well.
Following instructions will help:
1 When the generating set has to be taken out of its
enclosure we strongly advise not to do this in a
narrow space on a boat, but to take out the complete
set and take it to a workshop.
2 To take out the generator all connections have to be
taken off. The outgoing hose on the oil cooler is most
difficult to get to, but can be reached from above by
taking off the cover which is on the cylinder head of
the engine. By taking out 4 screws from the aluminium
bars the generating set will come loose from the
capsule.
3 The easiest way to get the generator out of its capsule
is by lifting the set using the lifting eye and removing
the capsule downwards.
4 The cooler elements are welded to the alternator
housing with silver and cannot be disassembled.

How-ever one can take off the complete alternator
housing.
5 Before the alternator can be taken off one has to take
out the fitting to the oil cooler to be able to take off the
aluminium housing. All cables and wiring have to be
loosened first.
6 The rotor can be taken off by removing the bolt which
goes through the shaft (normal clockwise threaded).
The end of the shaft is specially threaded to push off
the rotor from the conic stub shaft, which is on the
flywheel, using a 6-mm rod of 165-mm length and a
M10 bolt.
7 Reassembling the generating set one should take
care of alignment, cleaning the surfaces between
engine and alternator and tighten the bolts crosswise
and gradually.
8 Use Loctite 577 to seal the fittings, which should first
be cleaned and made free of oil and grease.
9 Test the generating set first outside its capsule and
check very carefully for leakages before putting it
back in its enclosure.
