RASs aren't like a TS - they aren't belt driven and are
direct drive. The motor is precisely engineered to fit in a yolk
with special hardware. What ever motor has to be rebuilt to fit the
housing of the original - a very expensive proposition.

Mine was a one of a kind with a universal motor and two aux spindles -
3450 & 20,000 RPM. Upon examination of the inards, 32 years of use
leaves it too close to the edge to make it worthwhile to rebuild. All
others I have seen are induction motors and one aux spindle at 3450 - much
quiter and in the long run, less prone to wear.

Anything is possible, but I suspect the custom precision machining would
cost more than a new RAS. Also, the main reason I wanted to fix this one
was that is had unique features that any new RAS doesn't - universal motor
allowing use of speed control and two aux spindles @ 3450 and 20,000 RPM.

look in the phone book and see if there is a shop that will rewind that
motor. If the saw is in good shape otherwise why throw it away. I don't know
if saw motors can be rebuilt, but won't cost nuthin to call and ask.

Would it be possible to purchase a new motor of same rpm and close to
the same physical size and build an adaptor (sleeve) to bolt it to the yoke?

Interesting info - it's a 315. which makes it a Ryan. I have not heard of
them and have no idea of their rep. Also, it would be interesting to
trace the mfg of the Ridgid, given the similarities.

Thanks,

Or grab all your specs and find something similar at McMaster or
Grainger or whoever else will sell a replacement motor.

You're absolutely right! Don't know what I was thinking. Must have had
tablesaw or compressor on the brain!

BTDT - It's a universal motor and the armature has spiral gears that are
almost non existant. To have it rebuilt would mean re-engineering and the
estimates I have are ten-fold of what it cost originally. It's time to
let go...

Doug...

Don't dumpster your TPC 2610 yet. I may have found you a
replacement motor. Mine is still going strong; but one of the
people working next door to me its twin; and may be willing to
sell. Let me know if you're interested so I can see if he's
interested. If you both are, I'll let you guys work out your own
deal.

Take down the model# off the unit (should look like 113.984058 or
something along that line) then go to this website:
http://www.edgeta.org/sears.htm
The first three numbers should indicate mfr.
