I need to replace the bearings in my Bantam Mag 10xg that I have had since 1983. I need to know the size because I cannot find a schematic for it. Also does anybody know anything about a bearing modification kit for the older model Shimano's? I saw one on ebay and was kind of leary about getting it until I had more info. Any help will be greatly appreciated.

Buy or borrow a dial caliper, millimeter scal, and measure them. Most bearing dimension are given as: inside diameter X outside diameter X thickness

PM ReelMech, he can give you the best advice. And, probably get you the parts. I know he can do the work for you.

Cheers,
