Here’s some pics of a Caterpillar Grader circle drive motor we’re rebuilding. The pinion gear, brass gear & worn drive gears were all worn requiring their replacement. The clutch assembly was pretty well hammered as well. We had to heat the housing to remove the bearing races as they were spun & fused in place. After we get all the bores & machined surfaces welded & machined back to spec we’ll get it assembled with the new parts that required replacement.
