First,
do you have the correct tools to remove and replace these precision parts?
Presses and plugs? Master Machinist available ?
I am not sure how they are configured, but just put them back the way the old bearings came out. If you didn't look, likely I would change paths and buy a reman spindle. You need special tools, precision reloads and assembles in a clean room environment. Any contamination inside the spindle will spell a short life. FadalCNC.com has both new and reman spindles in stock at the best prices on the web.
