I'm trying to reseal an old Ramsey 200 PTO winch. I'm disassembled to the point where the main gear housing is open and the gears need to be removed. I'm not sure which gear to remove first or how to do it. I don't want to break anything if possible because everything is in great shape and most of the hard parts are no longer available. I can press them out if necessary I just need to know which gear to remove first and if there are any tricks I need to know. All details would be helpful.
