Pump Gear Set - Inner Gear
This is the converter side of the inner gear.
Note the exit path of the bending converter tangs.
There is also a build up of material on the inner edge of the bottom portion. Perhaps this was caused by the tangs running against the un-turning gear?
Note also the pattern in the inner gear where the bushing should be.
A close up of the exit path.
There is a clear wear pattern where the gear ran against the pump body. Is this a normal pattern or is it excessive? The pump body surface this runs against shows some excessive wear which is shown on a later page.
Note the inner surface where the gear bushing was pressed into. Does this surface indicate that the bushing exited gradually or did it exit all at once?
