Here’s some pics of the internals of a Caterpillar grader circle drive motor while we were assembling it during the rebuild process. This one had a damaged bored internally that we had to repair & machine to give the bearing the proper press-fit. In these pics you can see the new bearings, gears & the large bronze gear that all had to be replaced.
