I have these hubs on this keyed shaft that im trying to remove. I bough the go kart/buggy so I didn't install them. I'm using wd-40 and letting it sit but I don't feel good hammering the crap out of my hubs. Any ideas?
Maybe it's just the pic, but it looks bent to me. Instead of WD-40, try PB Blaster. Try applying every day for about a week, then try again. If all else fails, try heating the hub with a torch.
PB Blaster can help almost instantaneously, it depends on how bad it is.
Harbor Freight sells a propane torch attachment, and they'll hook up to a standard propane cartridge. Might try that.
The 4 hole lug pattern is a pretty standard utility setup, race karts use a 3 lug. Measure the distance from center to center between two opposite lug studs. Usually it's 2 13/16", although some big ones are 4".
