Lapidary GemLap 5A - bearing removal

[johnataylor]

Hey all, I’m trying to replace the bearings on this old flat lap, but I’m having a bear of a time separating these final pieces. I got the first bearing and the whole shaft out of the housing using a my brother’s hydraulic press. I’m hoping to learn a bit more before trying to press this apart. Don’t want to break something I don’t have to.

Thanks in advance!

slide something over the 5/8 shaft that extends beyond the aluminum cup washer that will press on the inner race of the bearing . set that in the press . protect the threads on the other end & press it out
what is the ID of the bearing, 1/2 or 5/8?

The bearing ID is 5/8”. The steel flange/washer is not a part of the shaft, is it? That would not have been milled that way, right? If the steel washer moves it will have to come up over the threaded part because its ID is 1/2”.

my suspicion is that the washer is pressed on the 1/2" shaft , up against the 5/8" lip

That seems right. Thank you!
