G506 transmission bearing part numbers

Post by jeepsntank » Fri Jan 11, 2019 3:15 pm

Does anyone have military or chevy part numbers for the front countershaft bearing in the g506 4speed transmission ? or a new bearing for sale ? I am restoring my june 42 truck and have sourced all the bearings except this one . The old bearing is a hyatt ORB 1206 caged roller bearing
Any help appreciated

In the parts book I have it lists the GM part number 142260, which further reads (Hyatt C-1206). I did a search using that number and found a couple of places that supposedly sold that bearing, in a different brand. I didn't link to them because the sites seemed a little funky and I can't vouch for em. Do a quick search with the part number and you'll see what I mean.
