I am working on rebuilding a Bridgeport 2J head. I am disassembling the head to give everything a good cleaning and lubricating. I replaced the bearings on the small bull gear and noticed, after I reassembled, that the clearance between large and small bull gears is very tight for about 1/2 to 3/4 of the rotation of the large bull gear. I did not make note if this was an issue before I disassembled. The only thing that changed was I had to file a burr off of the bore where large bull gear raises and lowers. I'm assuming this isn't normal. Any tips or ideas how to resolve this would be greatly appreciated. Thanks!
