Thanks Tractorholic. Hoping I don't have to exercise that idea!Rims can rust tight to the keyed axles and be a bear to remove without damage to them or the transaxle..If you try using a hammer and block of wood to whack the inner side of the rim,often the axle shaft will come right out of the transaxle with it--it is only retained by a flimsy snap ring inside the transaxle case..
I've had some stuck so good heating up the hub with a torch after deflating the tire didn't help,using a steering wheel type puller bolted to the wheel weight holes in the rim--tightening the screw just started bending the rim centers..
One tractor transaxle I had I was determined to get the rims off of,I needed the transaxle for another tractor,and had the rims off the original one,so I didn't really care if I wrecked the rims getting them off,but would have preferred not to,so I'd have spares--I heated the hubs up bright red several times and tried the puller again,with no luck..
Then I had an idea--I tack welded a 5/8" nut to the rim hub,and put a 5/8" bolt that had long threads in it and used my air impact gun to tighten the bolt against the 3/4" axle,and the rims came loose,the bolt pushed against the axle shaft and shoved them right off ..worked slick..getting the welds off to remove the nut required some patience and careful use of the cutting torch but they were not scarred up badly enough that they couldn't be used again..
