This view shows one of two set screws that retain the drive pulley to the motor
shaft.
This thin plate fits over the upright posts without any means of retainment
other than being captured within the assembly and by gravity.
Note the small diameter thrust ball at the bottom end of the motor shaft.
Diameter of the sphere is 2mm. It thrusts against a nylon pad that is
attached to the bottom of the motor end cap.
Still assembled, the end cap with self-aligning bushing.
with the rivets drilled out, we can now see the internal bits 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 the bushing to rotate within a matching
socket so that the two end caps with bushings may be adjusted into 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; gripped by pliers firmly enough to indent the soft porous bronze
material.
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.
