Just picked up a "new" to me Rockwell 28-200 band saw on Craigslist, paid $400 so not a steal but once I sort out a few things hopefully it will be a solid saw. I assume it's the same as the Delta 28-200 although the name Delta doesn't appear anywhere. Serial number is 191740 made in Guelph Ontario. It has a Baldor 1 HP 110/220 V motor (not original) and is almost complete with original parts, missing the table pin- easy to replace, and the fence. Has a riser kit installed but the blade guard on the right side is original, not the longer version required with the riser. Includes miter gauge and a shop made fibreglass belt guard. As best I can tell it was made somewhere between 1972 and 1984, can anyone narrow that down?

Now the issues. Main issue is the upper wheel. The ID of the hub appears worn and the bearing is loose in the hub. The ID of the hub measures 1.389" vs the bearing OD of 1.378" and there is a spacer between the bearings that doesn't show up on the parts diagram in the manual. There are signs of wear on the back of the hub with some matching wear on the housing and shaft hinge (but minor), there is also signs that the rim of the wheel has rubbed on the inside of the housing (more noticeable than the wear near the hub). The shaft has c clips to locate the bearing outer races. What's the best way to resolve this worn wheel hub? The bearings themselves seem good but I will probably replace them while I have it apart. The front bearing is off but the rear bearing is still on the shaft with the wheel off. Despite the worn hub it runs smoothly (smoother than my Asian copy) although I haven't cut anything with it yet.
