Stormin 9,984 #1 Posted July 26, 2023 The nylon bearings in the three rollers on my 42" RD are past their sell by date. Also the spindles are worn. One very badly. Today I replaced them with rollers and spindles salvaged of a scrap SD. The deck was bent. Now the rollers are different diameters. 2-1/2" on the RD and 2-3/4" on the SD. I very much doubt that it should make much difference. Unless someone knows otherwise. May have to make adjustments to the deck height of course. One future day I may make some new nylon bearings for the 2-1/2 rollers. 2 Share this post Link to post Share on other sites
