Default Re: Tom Endy: Transmission Bearings (Hyatt style)

I will leave room for Tom to answer, but it is apparent the difference between your repop and your original is:

The repops (Hyatt?) have hollow "rollers" that turn on shafts captive in the retaining rings.

The original (Bower?) have solid "rollers" that have their ends "necked down" to match a hole/recess in the retaining ring.

Do I have this right?

Edit: I have now in my hand a set of bona-fide originals. They are marked "Hyatt" on the non-roller cage connectors (5 of these) and the rollers are hollow and "spiral" in Hyatt roller style. The rollers are space 3-2-2-2-2 as with your Bower bearing is above.
