I had a major oil leak from the gearbox of my Monarch Ser.60 lathe (13”, no Power Rapid Traverse) and, finally, became ready to find the source and fix it. Before starting, I met with Mike (Draglineguy) who shared with me his experience in removing the gearbox of his Monarch. His help was invaluable and saved me many hours of guessing. As a result, the actual gearbox removal took less than two hours.
I would like to share with you the step-by-step instructions and provide photos of the process.
I used Monarch Series 61 Parts Catalog and will provide part references/page # for those parts that are in the catalog (not all of them are). Note that the Ser.60 Parts Catalogs are worthless and only show a few parts, so don’t waste your money on them. Get the Ser.61 parts catalog instead.
Let’s begin.
1. Completely remove the oil plug from the gearbox oil sump (J56, p.20) and drain the oil.
2. Remove the round lid and gasket (H103,104, p.18) covering the cross shaft located in the lower right corner on the face of the gearbox. Remove a snap ring from the end of the shaft, if present. On the back of the lathe disconnect the cross shaft from the articulated arm (watch the key!) and pull the shaft away toward the back of the lathe.
