I’m changing the cutter knife head in my old Bridgewood 15” planer. It’s a typical 4-post Asian planer. From 1990. Started in on it today and everything is going fairly well. My main hold up so far is that I cannot get the old cutter head apart from the gear box. I have the gears out and I’ve tried hammering on the cutterhead a few different ways and it won’t budge. A few of the gears were difficult to break loose as well but I did eventually get them. Any ideas on how to deal with this? Would a squirt of PB blaster help?
Other questions are, should I replace the bearings and oil seals inside of the gear box? I am replacing the gasket and have new bearings for the cutterhead. My gear box has unshielded bearings. Would shielded ones would be fine to replace with?
Thanks everyone!
