Re: disc wheels split rim 28-31

Dear Sanford:

The original method was to use two bars and a hammer. One had a groove in it to catch the cut out and then push against the rim so that the second bar could be used to work the snap ring off of the rim. The same way as a tire machine using the hammer to move the ring along.

You will need to make these. The work off bar will work best if polished. Extra bars will come in handy as well.

Now care needs to be exercised because aggressive use of those bars can crack the rim lip. Use of tire assembly lubricant will also help.

Finally, when you put wheels together do not inflate them facing the snap ring because it can fly off and kill you. George Jepson owned a Shell station and saw an arm blown off. I adjusted the air in a set of snap ring tires and used safety straps to prevent my being blown up. Five mintues after I took the straps off a snap ring flew across the building and smashed a parked car. (The lock bolt broke).

Inflate the wheels with the snap ring facing the wall or floor using a rubber valve stem extension. (available from NAPA). Inflate the wheels in steps of 15-20psi, deflating the tires at least once to seat the tube. Now let the tire sit for an hour or two before removing the extension. Next lay out a blanket and let each wheel fall on the snap ring side. Then let them sit for at least a day.

Hope this helps and remember: another term for snap rings and lock bolts is - widow makers.
