I have a PC model 220 TS table saw. The two bevel gears P/N 34PR need replacing. They raise the blade up & down. I have the new gears. The gear on the hand wheel adjuster is no problem. BUT I can't figure out how to replace the bevel gear on the vertical worm shaft P/N 3685. I removed the screw that holds the gear to the shaft thinking that then I can simply "unscrew the threaded shaft out of the motor casting which the shaft pass thru, remove the old gear, replace it & reassemble everything. I can't figure out how this vertical worm shaft comes out of the saw without taking the entire saw apart. There has got to be a better way. I don't think Porter Cable would design something so complicated to take apart to replace a single part that's prone to regular replacement. Has anyone ever done this repair or can tell me where I can find the info on how to do it. Can't find a single thing on Youtube or on the net so far. Thanks for your advice.
