I used to have a pair of Morris Mags in 1990. My little brother lost the rear wheel in 1999 or so. I have always kept my front wheel. I just now started looking for a rear wheel. I can not find one so I bought the yellow N.O.S. front wheel off ebay. So now I have two front wheels. I have found out the front and rear wheel have the same U.S Pat. No. D232717 but are machined different the rear being bigger with a steel sleeve pressed in. This piece also includes the bearing races cut into it. I have a picture of a green wheel without the guts and also a paper add with an empty wheel. These are all I could find but I also have two pictures of a Motomag that used the Bendix 76 coaster brake, it's pretty much identical in the hub to the Morris Mag which also used the Bendix 76. My front wheel is 3.175" wide at hub with a 1.125 bore. I will have to have it bored out, My old hub is 1.600" (pic IMG_0608) so a little less -.002" or what ever the machinist thinks it takes to have a press fit into cast aluminum. Once bored out the rim will be narrower at the hub measuring 2.450". If you look at pic IMG_0613.jpg it shows how much will be cut out, losing the raised unpainted portion on both sides making the rim measure 2.450" at the hub. There is a picture called hub insert showing a aftermarket freestyle hub for a motomag. It has knurled parallel splines with a flange on the non driven side. I thought maybe I would do my Bendix 76 28 spoke hub like that but mine is not wide enough. It measures 2.025" inside spoke flanges, pic IMG_0610. It measured 2.250" outside the spoke flanges, pic IMG_0609. It measures 2.475" total width past flanges with it totally disassembled, pic IMG_0614. So. that is .025" twenty five thousandths more than the wheel. Once pressed in it should have .0125" hanging out of both sides. This will work. I might have splines cut in mine if the machinist thinks it needs it. Before I commit to doing this, are there any experts that know better than me about the Morris or Motomag Bendix 76 coaster brake design pertaining to the steel race insert in the wheels. Are there any broken mags available anywhere that I might get the bearing race sleeve out of or is that probably a pipe dream and go ahead and commit to my idea.
