I recently purchased a used 7x10. The previous owner faced off the chuck registration boss, so I have to replace the spindle. While I have it torn down, it has been suggested that I also replace the bearings and swap the plastic transmission gears with a set of metal gears.
I have done a good bit of research and have read the disassembly guide, but I still have some questions.
Is a hydraulic press absolutely necessary? I don't have one and really don't want to buy one. If I am going to need one, I will have to find a local shop to do that work.
Spanners for the spindle nut: I don't have 'em. Will I be able to remove these nuts without them, or do I need to track some down / buy a pair?
Metal transmission gears: are there any downsides to installing them? I understand that a spindle lockup / crash with the carriage can break the plastic gears. Since the metal gears probably won't break and that stress has to go somewhere, what will break?
Tapered roller bearings: is the seating / run-in / preloading process difficult? I've neve done it before and have no idea how difficult it is to do right. Also, the spacer needs to be cut down; how precise does this need to be? I can't very well tun it down on the lathe, so I will have to do it by hand.
Thank everyone, and sorry for the long post. I'm reasonably mechanically inclined, but have no real idea how difficult this will be. At least the guide makes it look easy...
