Have an SM160. One if the wheels came apart. Looked at a replacement wheel from Cookshack they want $40 for one 3" wheel delivered. Went looking for one at Menards. Had to buy four 4" wheels because the mounting brackets are too small on the 3". Must be a custom part for cookshack. So I replaced all 4 wheels for less than the cost of 1.
Thanks for the link! Got the new wheels for $8 each and I got it done same day. If I dont get it done same day it never gets done!
