How to get out JP3 rudder bearing
This top flange looks like it's threaded into the body. I've removed the set screws, soaked with PB blaster and took a chisel and hammer to try and get it to spin....no luck. It's real close to fiberglass, so I don't want to heat it with a torch. Any ideas?

Re: How to get out JP3 rudder bearing
Some of the roller rudder bearings are epoxied into place. Check with the manufacturer for installation/removal procedure.

Pipe wrench on the edge of that flange. If the flange is important, the trusty sawzall will ruin it.

Re: How to get out JP3 rudder bearing
those two holes in the top of the flange look like they are meant for a pin wrench, and that kinda implies that it is screwed into the hull.

Re: How to get out JP3 rudder bearing
Typically these bearings have holes in their flanges for mounting and adjusting a compression-type rudder shaft seal.

The holes in the top of the flange had set screws in them, which I removed. I tired using a an adjustable style pin wrench used for removing fuel/water caps, but it was going to break before the flange budged.

A blast of CO2 on the inside or pack it with ice inside.

Re: How to get out JP3 rudder bearing
Do a search on the JP3 website for drawings of the bearing. I have a different model which uses a self aligning plastic bearing. It was secured from the exterior by a plate with set screws etc. The top is glued in from memory and not removeable. My bearing was so stuck i had to drill/destroy the cover plate and drill/destroy the plastic bearing to remove and then wait 4 weeks for them to manufacture a new bearing. I dont know what grade of aluminium they use but it was almost as hard as stainless steel!
Good luck with that.

Re: How to get out JP3 rudder bearing
Sawzall can be such a useful tool when delicate work is needed.
Check the removable, composite Jeffa bearings. No metal plus they are easy to inspect and clean.
