Here's the 115.6963 motor from the free table saw above. The date code on the badge is L1 48. It's pretty nasty... the switch was removed, the wiring is fubar and it's packed with dust.
This motor is virtually identical to the 1725 rpm model 115.6962.
The "seller" mentioned in his fbmp ad that the motor did not work. In my experience, "does not run" rarely means "will not run". Usually, no-start problems include bad plug, bad cord, bad capacitor or tripped thermal switch.
I pressed the thermal reset, wired up a temporary cord and switched the motor on. Nothing.
I pressed the thermal reset switch again, more firmly this time, and heard it click. The sound was very similar to the centrifugal switch clicking at shutdown. I flipped the switch and success! The large cloud emitting from the motor is dust, not smoke.
So, the shutdown-to-stop time was a very long 50 seconds. The bearings are very loud and very dry. IMO, this further debunks the theory the long run down times mean the bearings are in great shape. I'm going to perform addition testing on shutdown-to-stop timing.
I've got the motor apart and could not believe the amount of saw dust pouring out.
The bearings cleaned up beautifully. Zero axial or radial play.
I completed the motor this morning.
With clean,
dry bearings, shutdown-to-stop time was still long and still loud as expected.
After lubricating the bearings, shutdown-to-stop was a much better 15 seconds and much more quiet.
