A friend gave me a old Penn green 700 for parts it has a frozen main bearing in the spool any tips to help unfreeze the drag bearing from any of you older wiser gentleman? It is a classic left hand retrieve.
Use the stuff posted above, heat the spool in oven to 300 degrees, place spool in a press with the area around the bearing supported and press out. Freeze the new bearing and heat oven to 200 deg. and press back into spool. Just a note... when Penn presses these bearings in, they don't use heat. It's just a light press fit so it won't take a lot of force to press out.
