The x-feed motor on the mill I bought has burn out and given the flange and length of the shaft, I decided to get it rewound. In order to remove the motor from the gearbox, I had to get to worm gear off the shaft, which necessitated stripping out the whole gearbox. Turned out well in the end, as the thrust bearing was shot and the other bearings had seen better days. The alignment also needed some attention.
Well it is all back together and I have a couple of questions. The filler is about an inch above the bottom of the gearbox, meaning that only the two lower shaft bearing and the thrust bearing would be constantly lubricated. Is this normal, or is this actually a drain hole?
Second, the bevel gear on the output shaft has 4 holes spaces evenly around the hub, which had a ball and spring in each, with the spring between the ball and the shaft. I cannot see the purpose of these and as they were virtually impossible to get them back in they are still sitting on the bench. Can anyone enlighten me?
