ttttrucks Posted June 30, 2017 Share Posted June 30, 2017 Hello every one I have a cracked Hub on my 1954 B Mack I have looked for a cast # I have read up on and believe the # is 8Q414 does anyone know if that is right? Also where a guy might find one? I might have a guy with one but he wants me to make sure of the cast #. Any ways hope some one has the answers I am looking for. Thanks Mike.

thomastractorsvc Posted July 8, 2017 Share Posted July 8, 2017 Salvage yard take it with you or to your buddies to compare. Probably won't find a casting number unless you sand blast it and then it way be worn off Quote Robert"I reject your reality and substitute my own."

Maddog13407 Posted July 8, 2017 Share Posted July 8, 2017 more than likely its a 507 or 508 or the like rear and they all used the same hubs, some had different bearings. might end up swapping out your races. Quote Link to comment Share on other sites More sharing options...

I have an 8QJ414 on my B46. Flickr photo below There was a couple of these in the Northeast area for $200 each plus shipping. I had a hub (not the 8QJ414) with what I thought was one crack - it had three cracks that I welded with a MIG welder. Cast steel, not cast iron so they weld without too much worry of cracking. It was a really poor casting that had a lot of factory welding/repair work - which gave me confidence in repairing/welding https://www.flickr.com/photos/emack/34284586823/in/album-72157684558130216/ 1 Quote Link to comment Share on other sites More sharing options...
