Starter/Bendix Questions - Tractor Won't Start

The 8N (12 volt) ran/started fine one day, and the next wouldn't turn over. Suspected the Solenoid, so replaced that and the starter switch. However, still wouldn't start, but made a humming noise (like something was stuck). I tried jumping straight from the positive pole of the battery, over the solenoid, directly to the starter, but nothing. I have since removed the starter and cleaned it. The motor turns freely. The bendix was gunked up, so I took it apart and cleaned all parts with mineral spirits. Everything seems to move freely. I did have to file down a "lip" of metal that had formed where a couple of pieces come together near the rear spring on the shaft. I also notice that the bendix does not appear to be returning all the way back to it's original position. I see wear on the shaft that makes me think it should go back farther towards the motor. I don't want to go through the pain of putting the starter back in the tractor without knowing if it's completely shot. Is there any safe way to test the started while it's out of the tractor? Any insight is greatly appreciated. Thanks. Karen

Not an expert, but something else to think about. Sometimes the starter will hang up on the ring gear and lock the starter up so it just clicks or humms when the button is pushed. If you had trouble removing the starter, like having to force the starter away from the motor after loosening the bolts, and then it suddenly released, that may have been your problem. If it was, and all else seems ok with starter, it can be replaced and will work fine for now. This is not the cure, but may get you by until you are ready to rebuild the starter and break the tractor and replace the ring gear. Some say, and it has worked for me a couple of times but not always, that when this happens, you can put tractor in 4th gear and rock it as violently as you can forward and back and starter gear and flywheel will disconnect and the starter is free.
Another thing: Make sure ALL your electrical connections from battery to starter and ground are clean and shiney and tight. HTH

IT SOUNDS LIKE YOU SHOULD REBUILD THE STARTER. YOU CAN APPLY BAT VOLTAGE TO THE STARTER WITH JUMPER CABLES. HOLD YOUR FOOT ON THE STARTER BECAUSE IT WILL PRODUCE ALOT OF TORQUE. THE BENDIX MECHANISIM SOULD FLY OUT TO ENGAGE THE FLYWHEEL. NO LOAD CURRENT WOULD BE ABOUT 70 AMPS, I EXPECT.
