My shooting club has motorized target carriers on the indoor range.
They use "Maxtorq" gear motors, and one isn't working. The motor
shaft spins, but the output shaft doesn't. It doesn't make any excess
noise like grinding of gears or anything. These have been in place
since at least 1970, and they have been so realible that I don't know
if anyone is around who knows much about them.

I suspect either a set screw or Woodruff key has let go in the
gearbox, but it's also possible that a shaft has snapped or a gear hub
has busted loose. I've never worked on one of these things & was
wondering if I should concentrate on finding a spare (we may have some
someplace), or try to repair it. If it's likely to be a quick fix, I
can leave it wired up & work on the gearbox end. Otherwise I'll have
to completely dismount it. The winter pistol league has just started,
and we need every firing point we have.

I found most of the nameplate data, although it was hard to read:

It's a continuous duty 115V AC reversible split cap motor, 25 in-lbs
torque, 124 RPM motor. Maxitorq seems to have gone the way of the dodo,
but Grainger has what appears to be a drop in replacement if we get
desperate:

I'm still trying to locate someone at the club who might know if we have
any spares stashed someplace. In the meantime, I'll start checking out
the surplus places Gunner mentioned and put a search up on eBay.

Thanks!
