Stike 204 #1 Posted August 28, 2017 Hi all, I am looking for a good source for the bearings and size for a freind who just got a 520h with 48 inch deck model 78360 serial 5901723, looks like bearing is toro no. 10966. Any help would be great, it's his first horse and in great shape, free from his father in law who bought it new, includes all original paperwork, I'm so jealous . Thanks for any help. I know everyone loves pics so even though it's just a deck this is before cleaning up, even the decals are nice. Can't wait to see the tractor. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,146 #2 Posted August 28, 2017 Should be a 6203 metric bearing. May have only one seal but often less expensive to get two seals and pop one out. Supply and demand. Garry Share this post Link to post Share on other sites
cleat 6,735 #3 Posted August 28, 2017 (edited) 6203 is correct. Looks like you need a new belt as well. Good looking deck. Hard to find without holes or welded on patches. Edited August 28, 2017 by cleat Share this post Link to post Share on other sites
Anglo Traction 761 #4 Posted August 28, 2017 Think your part # should read 109966 and as mentioned relates to 6203 series. The size is in inch and is stated as 21/32" ID. 1 9/16"OD. 15/32" HEIGHT in retail listings. Lots of options if search made by Toro Part #. One point that needs to be made clear. If the upper (old) Bearing from the Spindle(s) is found to have no Shields, then I strongly suggest he does a trial assembly on the Spindle to see if the replacement Bearing also needs to have both Shields/Seals removed if plan is to use Grease Gun in future. If the Spindle is like some others on WH Decks, the grease access point is above the top Bearing and if the upper seal is left in you will not get any grease to the bearings. Here is an example- The Example Spindle Ass'y is for a 1978 36" RD Deck (Double Shields were left in as there was no intention of future greasing), but is similar in layout with different dimensions and part numbers. Hope this helps. Share this post Link to post Share on other sites
skrusins 128 #5 Posted August 29, 2017 In Akron, Ohio there is a company Akron Wheel Bearing. They can cross reference any company's bearing and if you have the old bearing they will match it for about a third of the price. They sell all over the world. 2 Share this post Link to post Share on other sites
