A weak or broken plunger spring or a sticking plunger may also contribute to this problem. This problem is not too unusual on Delco starters. When the solenoid is energized the plunger is drawn into the solenoid and causes the switch under the cap to close. When power is no longer applied to the S terminal the spring moves the lever and in turn withdraws the starter drive from the ring gear. It also allows the switch to open and the starter motor stops turning. The load on the drive gear as it meshes with the ring gear keeps the drive from sliding back on the armature shaft. If there is a problem with the stop collar on the armature the drive may engage too far and there is not enough movement to allow the switch to open.
If the starter is removed from the tractor the load is no longer there and the starter will work like it should. Likewise it would most likely not show any problems if the engine were started. In that case as the engine started the load on the drive would be released and the solenoid plunger spring would be able to retract the drive.

We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
