Ralph,
As JST mentions, the motor will have to be dismantled to gain access to its internal electrical connections.
For someone not accustom to this type of task, it will be intimidating.
Match-mark using a prick punch or permanent marker pen on the shaft end motor bracket (22) with the field housing (13) FIRST so upon reassembling,
the two components are put back in their proper arrangement.
Already mentioned, remove the brushes.
Remove the pulley from the motor shaft.
Next, remove the four end bracket screws labeled (23) on the parts breakdown.
Using a cold chisel (or a screw driver) and hammer, carefully break apart the mating register fit of the end bracket (22) with the motor field frame (13).
Carefully pry apart the end bracket from the field frame. The armature should stay with the end bracket
as it’s being pulled out.
The next steps are going to be the more difficult.
The two long screws (20) holding the wound field in the frame will have to be removed followed by
the internal fan shroud (19) and the two spacer bushings (18).
Carefully match-mark the wound field’s position in relation to the housing BEFORE REMOVAL to know
its proper position for reassembling. The mark should overlap one item to another so upon reassembly,
it is put exactly back in the very same position. (This has to do with the motor’s brush neutral which we won’t go further into).
In pulling out the field, the leads on it will likely not be very long and you will have to
disconnect –things- as you pull the field from the frame.
AGAIN! Mark and identify how the wires are connected.
Once the field is removed from the frame, you’ll have to assess your wiring job.
On a motor like this, there are typically small spring-like end connections to the brush holders
that will (may) have to be disconnected (pried off the brush holders) to fully remove the field.
Depending on the age of the machine, some of the wires may be brittle and require additional electrical
sleeving.
There’s not a lot of room for excessive length wires to be laying around inside the motor when
you begin to reassemble the item. So as you replace/install a new cord, consider the lengths of the original
wiring as a guide.
Re-assembling the motor will require it to likely be held in a position so you can drop things back in.
Gingerly hold the frame (13) in a vice with what will be the output shaft pointing toward the ceiling if you will.
One of the tricky tasks will be aligning the bushings on the field laminations with the field mounting holes
before replacing the internal fan shroud and so on.
And as mentioned earlier, as you begin re-installing –things- be on the lookout for how the internal
wiring finds its home. No wires should obstruct the armature from turning, or even remotely rubbing on it.
Reassemble in reverse order.
Good Luck!
John
