not sure about the FP cat,but generally rudder bearings fit in through a slot machined into the lower face of the ball shaped housing then are turned 90 degrees so the shaft hole lines up and the ball shaped bearing is locked in place by the shaft.

to remove; turn bearing 90 degrees vertically then it should be able to slide out

Re: Rudder Bearing Replacment on cat

here is a photo of this type of bearing and the housing,
the rounded bearing (lower right) fits into the elongated slot in the face of the housing(left) then is turned 90 degrees

Re: Rudder Bearing Replacment on cat

Hello Ram. Good to see your still around. Where are you in Greece?

My suggestion on your question is to send Yeloya a PM. His yard does this work quite often and will know the correct answer if it can be easily communicated. Good luck and btw - Santorini by boat sucks

What kind of bearings do you have? What atoll described is correct if you have JP3 Type 1 bearings.

Re: Rudder Bearing Replacment on cat

I have the same style bearings and housings and have replaced the spherical, plastic bearings and have helped other owners replace the housings. The only reason you'd have to "cut it out" is if you need to replace the bearing housing. The white plastic bearing will rotate inside the housing and you align the flat top and bottom with the slots in the housing to pull it out. It may be difficult to rotate, you just have to work it free. JP3 does not keep drilled bearings on the shelf - you specify the diameter of your shaft that sits in the bearing and they custom drill them to order. The housings come in different sizes and this is how you ID the bearings. To determine the housing size measure the OD of what you see and back track it using that dimension to pick out the size from JP3's online information. Replacing the housings is not that difficult. You would have to repair any hull damage from removing the old housing, then just glue in the new housing with 5200, taking care to maintain the same vertical dimensions.

Yes. That is what you need to do. A piece of wood and a hammer for persuasion help.

Re: Rudder Bearing Replacment on cat

Wow, that was easy, Iwant to thank you Guys I really appreciate the help...i had to cut through about a foot of stone as the rudder was longer than the ground,that took 4 hours the first time around, and was a disappointment that i could not do it, fearing id screw it up with out a housing, so i put it back together and figured next time, I came back here on CF and two hulls ,Dave your post allowed me to understand how it was done so i dug the hole out dropped the rudder and had the whole job done in 1/2 hour THANKS to Dave,Atoll SV Neko and the rest of you guys
