Replacing Motor w/a new one

Has anyone removed the sheaves and spring from the motor shaft? Somewhere I remember reading a procedure to safely remove the spring and reinstall it. My motor burned up a couple of weeks ago and Shopsmith indicated that the new one would be shipped around February 15th. I tried to have the motor rewound, but the going price around here started at $600.00!
So if anyone can direct me to the proper tool to safely get that spring off and back on I would appreciate it.

I think you should start look around the 8 minuet mark if i remember correctly.

Hope this helps

I recommend that you copy the following 25 maintenance procedures to your computer and to a backup disk:

This procedure covers the motor spring:
2. Replacing the Motor Spring

I make the board 24" long so I have more area to push on to compress the motor spring.

And I suggest that you drill a counter bore hole about an eighth of an inch deep. Then drill the through hole.

Why not wait for the new DVR motor? Seems like a great opportunity to upgrade to me, unless you just have to have a motor now.

Hi;
WOW!!! $600 bucks for a re-wind?? Sounds like someone does not want to be bothered. I believe that the motor ID numbers on the legend plate of the motor gives a number that will correspond to a standard winding assembly that might be obtained from the motor manufacturer. On the Emerson motors the winding set is something like CD55R or CDR55 can't remember exactly. If a motor shop orders the proper winding set and frame it should be only a matter of swapping one field frame for another.

Good Luck getting that from Emerson!

I have been successful in getting similar information from Emerson but not for the motors used in the Shopsmith equipment.

In most of my attempts, the technician was not able to 'identify' the numbers I was attempting to cross reference. On one occasion I spoke to an individual who asked me what the motor I was inquiring about was used on. When I answered the response was "Oh, that's why I can't find it. This motor is proprietary". She no longer was willing to talk. End of discussion.

The frame number (as you have referred to it) on my Mark V motor is C55DDR-2015C. The frame number on the Power Station/Crafter's Station is C55FLE3119.

Neither of those numbers have yielded any meaningful information. The information is there. It is just well camouflaged. Example.
