kthelton Posted November 12, 2013 Share Posted November 12, 2013 Ok guys I've got an rd690s with Dayton style hubs and wheels and I'm thinking of converting to budd style has anybody done this? Just wondering how to figure out which ones fit when I go to salvage yard.

krismoriah Posted November 12, 2013 Share Posted November 12, 2013 measure the stud size on the axle cap, measure from the top outside of the hub to the first bearing race.doing my second conversion next week. $150 per hub with studs and nuts and a good drum is fair. Buying all the studs and nuts and drums...after the fact is very expensive..so keep a good eye on what u are getting from the salvage yard or it will cost u when u assemble.Also factor in new rimsX 8. Good used aluminums- $150 each. $2000 for a conversion on two axles is getting by cheaply once u figure in the 4 new seals.

gearhead204 Posted November 12, 2013 Share Posted November 12, 2013 also get the brgs. and race #s for the inner and outer and double check the seals. the parts are too damn heavy to do twice!

I thought you would measure the spindle and where the hub races would ride. Quote Robert"I reject your reality and substitute my own."

gearhead204 Posted November 14, 2013 Share Posted November 14, 2013 I had to read it twice but I think he's referring to the axle flange dia. and axle retaining studs Quote Link to comment https://www.bigmacktrucks.com/topic/33467-1990-rd690s-hubs/#findComment-216650 Share on other sites More sharing options...
felicello122 Posted November 15, 2013 Share Posted November 15, 2013 I got 4 budd hubs off my 2000 rd, the rears were 44000 pound rating, I changed the ass end to 38000 pounders, I have 4 axles also, my housings are cracked and my rears are tired, hubs are good though, I don't have the drums cause I reused them, call me if you are interested, 914 474-7383, my name is Dominick.
