Have an older Murray Wide body riding mower (model 40507x8a) and am in process of rebuilding and restoring it. The steering wheel is held to a splined shaft by a 1/4 / 20 small bolt and washer. Have removed bolt but can not remove the steering wheel from the shaft. Been soaking in various rust busters, oils etc. off and on over the last year. Got it to move about 3/8 inch with a pretty heavy puller and with a 3/4 inch 3 ft breaker bar. But can not get to move any further. Even a heavy duty impact wrench stalled. Been looking at all the various posts about this problem everywhere and I thnk I'm going to have to do what many have ultimately ended up do, which is to cutt off the steering wheel and buying a new one. Since this is a plastic steering wheel on a metal splined shaft I wonder if anyone has found some kind of "secret" anti-zeize chemical that could work better with this plaastic that is sorta welded to the metal shaft.
