Subject: [atlas-craftsman IO] Craftsman Lathe 101.07403

Greetings,

I’m working on getting the subject lathe up and running. The Timkin tapered roller bearings on the spindle were made in June 1946, so I figure the lathe was produced when Craftsman started selling lathes after WW2. I would like to know what precision class the original tapered roller bearings were. Would they have been Standard (Class 4 or 2), or would they have been Class 3. It is my understanding that Timkin ?Class 3 tapered roller bearings are no longer available for the subject lathe. Is that correct?

The product numbers for the Timkin tapered roller bearings are 16150 for the cone and 16284 B for the cup. This assembly is currently available in Standard Precision (Class 2), but what precision bearings did the lathe originally come with. There is a 3 engraved on the cup & cone of the bearing set. Could that be the class of precision?
