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.
