40x74x40 bearing

I have to replace my wheel bearings and carrier bearings and I was wondering if anyone knows the sizes of the bearings and seals. So I can get them before taking everything apart.

not sure what Quad you have.
My 2001 Polaris sportsman 500 HO 4x4 has a rear bearing size of 40x74x40
not sure on the front ones yet as I have not taken them off yet but will post sizes as I change the front bearings

I just got my front hub bearings off ebay from Lytleracinggroup. They do have a website. Their ebay was still cheaper. Hope this helps.

Hey SlimShadie what size are the bearings? and what year type of bike are they for?

I already installed the bearings and cups. I know they were the AB25-1500 kit by Alls Balls, $11.80 each hub. I can't find the sizes any where, but it says its for 03-07 Predator.

The best reason to know the sizes is so you can go to a generic bearing shop and pay less money for the same thing!
so if we made a list of bearings sizes for different quads we could use it as a reference for all of us
