Question:

I’m looking for bearings/races/seals for Dico 15638-A hubs. I picked up a caliper to measure the existing ones. The inner bearing has an inside diameter of 1.37” and the inner race has an inside diameter of 1.93” and an outside diameter of 2.36”. The outer bearing has an inner diameter of 1.06” and the outer race has an inside diameter of 1.63” and an outside diameter of 1.98”. The inside seal has an outside diameter of 2.57”.

Thank you for the info on your Dico 15638 Hub!

The info you gave tells me that your hub fits a #84 standard spindle so you just need the Hub Bearing Kit # BK2-100 and you're good to go!
