I was given a metal Mantua TYCO Baldwin RF-16 A unit that did not work.  After spending an hour disassembling and testing, I decided the armature was never going to pull a load again; I began to consider ways to re-motor this "Shark".
In the "junk parts" bin I found an early(?) TYCO/Mantua MU-2; corroded and a missing wheel; hmmm, not quite right, but nothing to loose.  Knowing these units often "die" from lack of lubrication and with drill in hand, I removed rivet ends to reveal gears; I removed axles and applied electrical power to the brushes. Squealing as if in pain while spinning with vigor, it tested OK for my purpose!
I removed the brushes, drilled out a rivet securing the magnet,  removed bearing retainers, and got the armature in hand.
I disassembled the "shark" motor, using only a screw driver, getting armature in hand.
Comparing the two armatures, the MU-2 has a some-what shorter shaft. The bearings are quite different. Oh, well, nothing ventured, nothing gained! I popped off worm gears and bearings; slid "shark" bearings onto the shorter shaft and pushed "shark" worm gears on "enough" to feel secure.
Upon re-assembly, "Shark" runs smooth and with power!

That's great.
It's good to know that the MU-2 armature will fit.

If you can't fix it with a hammer, you've got an electrical problem.
