jeepwm69 7,600 Posted December 9, 2019 Since bearings and finding decent bearings at a reasonable price are something that comes up often, I figured I'd post up some bearing sizes that I've run into doing projects. 350D rear end bearing part numbers Axle Pinion big bearing is 63/22 2RS Seal is 38x64x11 Two ring gear bearings are marked 6007RS Seals 35x49x6 and 35x54x6 Small pinion gear NK14x24.5x15 Axle tube bearings are 62/28-2RS and 60/32-2RS, two of each.

jeepwm69 7,600 Posted December 9, 2019 I did nose around on a somewhat-local place's website and found Koyo bearings cheaper than Honda (same bearings) for most Foremans and Ranchers. Left rear bearing https://www.thebigbearingstore.com/koyo-60-32-2rsc3-radial-ball-bearing-32x58x13/ Left rear seal https://www.thebigbearingstore.com/42x58x10tc-metric-oil-seal/ Rear brake drum bearing https://www.thebigbearingstore.com/koyo-62-28-2rsc3-radial-ball-bearing-28x58x16/ Brake drum inner seal (inside of brake drum, going into axle tube) https://www.thebigbearingstore.com/34x58x6tc-metric-oil-seal/ Rear drum outer seal...this is a 14mm thick seal and the factory is 19mm thick I THINK it will still work but I'll let the experts chime in. https://www.thebigbearingstore.com/41x76x14tc9-metric-oil-seal-w-lip/ Share this post Link to post Share on other sites
