clueless 2,963 #1 Posted October 16, 2019 (edited) Is there a sealed bearing that can replace the 109966 deck bearings? My 1974 B-80 36rd deck had non greaseable bearings, and they lasted for years. Edited October 16, 2019 by clueless Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,921 #2 Posted October 16, 2019 I think the 109966 is a 6203 bearing. Add -RS for one seal and -2RS for 2 seals. Bearing dimensions .669"x1.575"x.472" (17mmx40mmx12mm) Garry Share this post Link to post Share on other sites
JoeM 7,871 #3 Posted October 16, 2019 Just bought 6 of these, for a 48 inch deck, from Ebay, Timken 6203-2RS-C3 Double Sealed Ball Bearing, 40mm x 17mm x 12mm, 6203-2RS $4.97 plus shipping. Might be able to do better if shopping around. Unbranded or knock offs are cheaper. Seem to be all Chinese made. I like sticking to SKF or Timken, just used those two brands when I worked and had no issues with quality. Share this post Link to post Share on other sites

I had a Yard Man for some 20+ yrs mowing with it a lot and it also had sealed bearings and IIRC I had one failure and changed them all out another 2 times when I had the deck down for other probs (aluminum spindles were prone to break) So, for the last 3 times I have went into a horse deck I just use sealed (seems they come that way anyway and are told to remove the shields if needed) Am presently running a 48" on my D200 with about 4 yrs use on the sealed ones --- MUCH better than that grease glob packed in the spindle housings!! 1 Share this post Link to post Share on other sites
FAST 87 #5 Posted October 19, 2019 Is this the sealed bearing size for all the spindles? I have a 42” deck on my c141. Looking to just have this not break down on me. I would rather do some preventive maintenance now so I can possible avoid a broken part. Thanks for the help. Share this post Link to post Share on other sites
pacer 3,160 #6 Posted October 19, 2019 Youre wise to do some 'preventive' maintenance -- especially if you have never went into your deck. If the bearing fails and is not caught quickly it can mangle the shaft and/or the housing. I would think that is the bearing you would use, they arent really all that expensive. Prowling the bay I found 10 of them for less than buying them one at a time -- 2-3$ apiece IIRC.... I get a ziploc bag and a paint paddle and start scooping that old grease out of the cavity - its usually a HUGE mass of it, and then with a roll of paper towels finish the clean-up ---- Ahhhh! Sooo much better!! 1 Share this post Link to post Share on other sites
