I recently rebuilt a Bobcat 371 skid steer and have found the rims were very loose after minimal use.
Originally the rims were held on to hubs using wheel bolts, but the threaded holes in hubs were worn enough that I went with bolts through the hubs and lug nuts. However, it appears that the rims don't have a deep enough "dimple" around the lug holes to let the cone of the lug nut center and hold the rims tightly.
The rims were new with the rebuild, and now one has had the lug holes reamed bad enough to need replacement. I'm thinking of welding the bolt heads on the back side of hubs enough to hold tight (and prevent backing out) and going with lock washers and nuts (and Loctite) to get more clamping power around rim hole.
Sorry for the long post. Any thoughts or similar experience?
