Bearing part numbers

Recommended Posts

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.

Axle tube seals are 42x58x10

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

Left rear seal

Rear brake drum bearing

Brake drum inner seal (inside of brake drum, going into axle tube)

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.
