I have an older vermeer 1000. Serial # 101. I have the drum out and I'm replacing the bearings. From what I can tell on a dial caliper and a tape measure the diameter of the shaft going through the drum is 2 3/16". Could someone give me re assurance. And any advice on bearing selection etc...any other things maybe I need to do before I install it back in? Thankguysz. I'm in a time crunch as well.
