Manual hubs: Pathfinder Equipment Co., Dual-a-matic, Selectro.
External and internal hub style found on many Pathfinder vans. There have been a number of manufacturers of this type of hub, with minor changes in design depending who was building it. Easy to take apart and reassemble. There is one universal rule to obey when disassembling this hub. There is a group of three screws that attaches the cap to the body of the hub. There is also a set a three screws with tamper proof heads that hold the cam in place. If you take these out, make sure you line up the holes in the cap with those in the cam. If you don’t, you will shatter the cam when you tighten the screws and your hub will be no better than a paper weight for your desk. Cams are hard to find, so be careful.
