For anyone else who runs into a Powermatic 87 bandsaw......
Powermatic 87 bearings. Beware there are a couple different transmissions for this model, not all bearings are the same among the variant models, the manual for ” maintenance instructions and parts list” ( from last page ,May 1979) shows the bearing for my model 87;(should show on page 34, transmission assy 87 lbs 0340058 on lower right of page ). There were no numbers to denote the correct manuals ( !*&#@), go figure

Bearings are easy enough to replace, a little tough if your bearing press decides to blow a seal when you need it, like mine; resorted to plastic hammer to get the bearings installed, needle bearing needed a blind bearing puller.
My Powermatic was from an auction, was not used a lot, almost all the bearings needed replacement, only 2 still had functional life. A couple bearing were bad enough to slightly score the shafts they were on, though no major damage. Damn these machines were mad to last hundreds of years. If the Pharaoh's had these around, their tombs would have had one of these for the after life's man cave.
it's called "I.R.O.N." - "inspect and replace only as necessary"
I hear it is pretty tough replacing main turbine shafts bearings at 34000 ft.
