Hi Team,
not sure if we used to machine out the old sheaves to accept the upgraded sealed bearings, something tells me we did, but, I may be wrong again--think box is slowing and missing on a few cylinders these days.

Or as someone was heard to say "I still have most of my marbles, they just roll slower these days"

This Product Bulletin Article from March 27 1961 may allow the Dealers to supply these bearings, if available still, to adapt old sheaves.

3F861 is now a 3F0861, and 3J168 will be 3J0168 to suit the computer technology 6 digit part numbers of today.
Your mileage may vary.
Cheers
Eddie B.
