Here's a list of the roller bearings I installed on my 46 1/2 ton. If you're looking for the numbers and make, here they are:

Outer smaller bearing:

Brand--Timken #LM11919 and #LM11949 (one is the bearing, one is the race)

Larger inner bearing:

Brand--MBS #909052R (all one piece)

Seal:

Brand--Timken #6064

I think these will fit many other years as well, hope this helps you.
