Re: Drum brake interchange

[farna@xxxxxxx]

The important thing to remember is that the backing plates must be changed also. If the axle is the same (AMC 15 to AMC 15, or 20 to 20) you should be able to pull the hubs (not an easy chore, and make SURE the axle nuts are torqued to 250-300 lb/ft when reassembling!) and swap backing plates and drums easily. Pulling the hubs is the only hard part. Swapping from 20 to 15 might require spacers between the hub and drum and filing the center hole. I can't think of why a drill might be required, unless it's to mount small screws to hold the drum on -- something that would be nice if spacers are required between drum and hub. 

Washers can be used for spacers, but NOT the garden variety hardware store type! Get GRADED (even grade 3) washers -- they should be of uniform thickness. Garden variety aren't.
