Step Four – Reassembly
Place the rear generator case on the bench top – orienting the generator case so that the
rotor assembly can be gently lowered into the case until the end of the rotor shaft enters the
rear needle bearing.
At this time take particular care that the output terminals are positioned, in relation to the
generator mounting foot and tensioning tab so as to meet the needs of your particular
installation.
Once in place the generator should be placed on its side.
At this point, gently press together the two case halves insuring proper fit of the stator
assembly’s iron laminations into the front case assembly. NOTE the two parts may not be
in full contact at this point – however, the case parts will be pulled into position as the case
bolts are inserted and tightened.
Insert the four case bolts removed previously making sure, if reassembling a model SR200
series generator, not to forget to position the generator’s four stainless steel 3/8” spacer nuts.
Loosely firm up all four bolts then continue to tighten an opposing pair to a moderate degree
of tension. Then do the same with the other opposing pair.
Now, moving around the generator, moving from one adjacent bolt to another, tighten the
bolts bit by bit until all are fully secure.
As a final step, remove the wire segment holding the brushes away from the slip rings. On
the SR150 and SR250 series generators this wire extends from inside the case near the rear
bearing support. On SR200 series units you will likely need a pair of needle nosed pliers to
grip the wire and pull it free of the rear case.
This completes the reassembly process.
Your generator may now be retested, and if found satisfactory, returned to service.
