I need help fixing a spindle of a Bridgeport Interact 412, if anyone has a schematic or a manual I thank them very much, I have no information of the machine and I have to change the bearings urgent. Thanks guys.

I was in the clean room of the Bridgeport Spindle rebuild area. Please read what I just said. Clean room. Spindles are a science. Bearings are very expensive because they are precision and matched and preloaded. Even the amount of grease (kluber) has science behind it. Too much can generate friction and heat. My recommendation is that it be sent out to a spindle rebuilder who will guarantee his work.

Thanks George for your advice, I must also do the repair myself and that where I am (Argentina) can not find someone qualified for the job, so it is seeking information for the job is well done.
