Lee1977 7,206 #11 Posted November 23, 2021 (edited) The only thing you need the number for is the mower blades and belts I'm sure someone can help you with that. It has metric 17 mm spindles the bearing are number 6203. The pulleys and Idler will be the same as any 42" Metric WH deck.

I was looking thru the blade selection pdf and noted many different 42" RD decks. I would assume something would have changed between models. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,475 #13 Posted November 23, 2021 Early bearings for decks with 3/4" blade hole is 6203-12 (12/16" = 3/4" ID) Late bearings for decks with 3/4"center hole is 6203-RS or 6203-2RS depending on the number of seals. (17mm ID is .669 ID) The OD of the 6203 is the same - 40mm Many years ago bearings used in North America were mostly inch sizes and in Europe they were metric. The metric won out so we ended up with many hybrid bearing sizes so older equipment with inch sized shafts could be maintained. Fafnir and New Departure are two very old companies that supplied North America. Share this post Link to post Share on other sites
