Disassembling instructions
It could be necessary to disassemble the generating set
for repair or checks. Following instructions will help:
1
The design of the
W-SQ12
makes it possible to do
most repairs on the spot. The connections of the
alternator are very accessible. The same is true for
the diode of the rotor
2
The sound shield can be disassembled according to
exploded view below (figure 28).
3
To take the generating set out of the canopy all hose
and cable connections have to be taken off. The set is
fixed to its base by four rubber mountings and can be
loosened by removing the four nuts from the bolts of
these mountings. The easiest way to get the
generator out of its capsule is by lifting the set with the
aid of the lifting eyes.
4
One can take off the complete alternator housing.
Before the alternator can be taken off all cables and
wiring has to be taken loose first.
5
The rotor can be taken off by removing the bold 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 10-mm rod of 245 mm length and a
M24x2 bolt.
6
Reassembling the generating set one should take
care of alignment, cleaning the surfaces between
engine and alternator and tighten the bolts crosswise
and gradually.
7
Use Loctite 577 to seal the fittings, which should first
be cleaned and made free of oil and grease.
8
Test the generating set first outside its capsule and
check very carefully for leakages before putting it
back in its enclosure.
