I first thought it was an HO72 but the bolt pattern is different than a HO52 that I have and I thought they were the same I might be wrong though. Also there is no thrust pad that I thought all the Eaton HOs had. Thanks Pics of axle | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy spectra, that is a Timken rear axle. Are there any numbers on the tag? Does it take the same wheels as the front axle? I'll look in my books and see what I can find. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy spectra, can you tell us your series designation? A 57 250 series with a V8, lists a Timken B100 as standard equipment, could that be it? | | | | | Joined: Aug 2010 Posts: 11 New Guy | | New Guy Joined: Aug 2010 Posts: 11 | 3B thanks for the replies it is a V8 250 series the numbers on the axle are B101HX1 and 176497 it has a 5.14 ratio. and yes both front and rear are the same eight bolt. Do you know if parts are available like seals and such? Thanks
