A.K.A. as Ground Sleeve Bushing
There are no apparent tracks on the outside of the bushing or the inside of the inner gear caused by the exit of this bushing.
If this bushing "fell out" there is no indication on the outer surface that it did so a little at a time. It would have had to "fallen out" very suddenly.
The wear pattern inside seems to indicate that it did indeed rotate on the race of the ground sleeve.
There appears to be extra wear on the outer edges of the wear surface.
Could this bushing have been released by thermal expansion of the inner gear due to the obvious overheating while the bushing its self was cooled by the mass of the ground sleeve?
Did the bending tangs just jerk it out?
The bushing was found intact but detached from the inner gear.
It was still around the ground sleeve but obviously not on its race.
It was in the "grip" of the bent tangs.
The discoloration indicates that is did reside in the inner gear for a long period of time.
Note the wear mark on the right side of the stakes.
The current outer diameter of the bushing is 2.995 inches. The inner diameter of the inner gear is 2.993. The bushing will not slip back into the inner gear.
