leversole Posted December 8, 2011 Share Posted December 8, 2011 According to the service manual I have, all of the FA-5** series axles use the Type III spindle...would it be safe to assume that the wheel hubs from any FA-5** series are interchangeable? That is the bearing sizes, hub length, etc?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/22017-spindle-sizes/ Share on other sites More sharing options...

Freightrain Posted December 8, 2011 Share Posted December 8, 2011 You trying to get budd hubs? You have the same axle as me, and Barry and I went round and round years ago with a few people trying to see what hubs crossed over. I gave up, I have all the bearing sizes and spacing wrote down. 10 years and still looking. Quote Larry 1959 B61 Liv'n Large......................

I gave up, I have all the bearing sizes and spacing wrote down. 10 years and still looking.If you post it I would love to have that info. When I redid the rear brakes I found a cracked spoke on mine. Hard telling how long its been that way because I didnt see it until hour six with the pressure washer and oven cleaner!

Rob Posted December 16, 2011 Share Posted December 16, 2011 ya,,,i would like to go to 5 spoke oil type bearings,,but wouldnt know where to start,,i suppose thiers a buncha differant ones urg!!!!!!...bobThere are oil, and grease seals. You can use oil seals with grease packed bearings but not the other way around. Of couse when using oil in the hubs you need oil hubcaps such as Stemco style.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

leversole Posted December 17, 2011 Author Share Posted December 17, 2011 What vendor did you use for the seals...the SKF site (who now owns CR) doesnt list that part number, searching by size (4.875 OD X 2.5 ID) gets nothing Quote Link to comment https://www.bigmacktrucks.com/topic/22017-spindle-sizes/#findComment-94448 Share on other sites More sharing options...
Freightrain Posted December 18, 2011 Share Posted December 18, 2011 I don't think I actually changed it when I had it apart 10 yrs ago? Just wrote the number down. I did the king pins, cleaned everything up, freed up the frozen brakes(been unhooked for years) and cleaned bearings. Don't really recall what I did with seals? Been a long time.

Rob Posted December 19, 2011 Share Posted December 19, 2011 The Stemco part number for the front wheel kit including inner oil seal, and wear ring is: 382-8011. The wear ring is Stemco 310-1051. The oil seal is Stemco 320-2031. These numbers are conversions from the former numbers of the Stemco seals that were installed originally, and are discontinued. I have oil hubs on the B67 these are for with an FA-517 axle. Hope they help you out.
