Mike,
The steal gear is the replacement as Plastic ones Did have the Occasional problem of the gear breaking off a tooth.
I modified the squirrel cage Intake area by grinding the case out and put a Radius on the front where the oil was picked up... one slow pick-up area that HD designed poorly in my book. But that was long ago, 97 was my ride...
The other thing that I would recommend ON next change; is to Bleed a little OUT the drain tube AFTER filling tank with new oil..... There CAN be an AIR Lock to the pump at times that Can Cause the oil Not to Flow... Drain Just enough out the drain tube to clear air out...
AND remember, always check the oil when put away AFTER a ride Hot... FULL when put away, not seeing any on the floor...It has to be full.. USUALLY the oil tanks up high on the side (sportsters and softails) will drain a LOT Down into the engine... Sitting over night my Sport is WAY Low in the oil tank, looking 80% empty... BUT FULL when checked after last ride...... SO when it is first started, NO Blipping the throttle and in about a minute or so of Normal warming (Evo's need that warming) at an IDLE the oil will Pump back into the tank... ESPECIALLY now that the return Squirrel is there and Working.
When you changed oil, the oil was Down into the engine sump and I'd bet it never got a Full oil change because of that.
Careful on Over Filling... and do the above running then check it properly AFTER it is repaired...
Too much will show up and maybe over flow with the Plug out of the tank...
Take Mama's turkey baster and remove Over full condition... Shussssh,,,,, don't get caught...
PS....
I know it IS Not your bike BUT let the owner Know what you Learned here...
