*The TD124 Motor: E50
*
Above motor assembly: As found on chassis #2128 The photo indicates that the motor, complete with wire harness, can be removed intact. No need to de-solder anything.

Photos are in order of disassembly.
*
This view shows one of two set screws that retain the drive pulley to
the motor shaft.
*
This thin plate serves as an EMI shield and fits over the upright posts
without being clamped in place, other than being somewhat loosely
captured within the assembly and gravity.
*
The fit is close between plate and posts. To remove - the plate
requires keeping it level while lifting over the post tops.
*

*
Note the small diameter thrust ball at the bottom end of the motor
shaft. Diameter of the sphere is 2mm. It thrusts against a
flat nylon pad that is to be found in the bottom of the case.
*
Still assembled, the end case with self-aligning bushing.
*
With rivets drilled out, we can see the internal parts of the bushing
assembly.
*
This one is nearly dry with only small amounts of lube still clinging to
the appropriate parts. The felt around the bushing is designed as an oil
resovoir. Bushing material is porous bronze (oilite). Also a material
that retains lubricant over a long operating life.
*
The spherical end of the bushing allows it to swivel within a socket of
matching form so that the two end caps with bushings may be adjusted
into concentric alignment over the motor shaft. More about that on
assembly.
*
*
*
*
These bushings aren't that pretty. Note the flat spotted surfaces on the
outer barrel, plane end of the bushing on the right. My guess;
inappropriately manhandled. The Oilite material is quite soft and does
not tolerate being gripped by pliers.
*
The bushing on the right appears to have suffered an "oops" at the
machine shop. I'll check the bushing inside diameters for size and wear
later. But right now, I'm thinking about how I'm going to source some
new replacement bushings for this motor. This will be an uncommon
specialty item.
