Hello, I have not posted before. I hope this is found useful. I recently updated my 56 greenie with a used 1.25 HP emerson motor. The rear bearing was odd like JPG40504 said. I found that Emerson uses a .625 centrifigul switch on the rear of the shaft neccitating the use of a .625 bearing. I could not find the Nachi bearing 620310 NSL but did find this which seems to work very well from VXB bearings
rear emerson motor bearing 6203-2rs-10 sealed.
The front or "fan" motor bearing is a standard 6203
Hope this is a help.
It is also correct(1 1/8hp).:)

This thread was started in March of 2009 and the first post contained,
"The control/idler shaft bearing is >>>> Water pump shaft...shaft and bearing are one and is not repairable by the average joe. Anyone found an aftermarket replacement? Also, the small bearing on the speed control sheave is pretty much not repairable as near as I can tell."
Are there aftermarket replacements for these two bearings? If so, what are their specs so I can order them?
Why did the poster say they are not repairable? Does it take special techniques or tools?
I have a 500 of mixed vintage (not sure who the father is). In some post there was a comment about SS making a change to the eccentric. Did this impact the bearing?

It replaced the modified water pump bearing with two standard ball bearings and a new shaft design. The eccentric was changed at that time.
The control sheave bearing is also modified making it 'unique'. SS does not sell it separate from a sheave. I believe the water pump bearing is now obsolete. IMHO the new design is better!!!
