The turning ball isn't replaced often. But when it needs replacing it must be done immediately or it will ruin your keel cable. We keep a spare in our tool kit. Each time we replace the keel cable, we remove the keel cable hose and check the turning ball carefully. If there is any indication of wear at the bottom of the groove, replace it and order another spare. If not, keep it in your tool kit for use after the next inspection.
This C-22 keel turning ball is an improved design with a Delrin bushing. The ball is a rather small diameter, especially when measured at the bottom of the grove. Any wear or debris will prevent the rotation of the ball. We have added the Delrin bushing so the ball will turn more freely and to eliminate corrosion between the ball and the pin. Fits all Catalina 22's and the Catalina 22 Sport.
The keel turning ball rotates on this pin. The pin is held into the bronze through hull tube by the keel cable hose. This improved pin is made of type 316 stainless steel for better corrosion resistance than the original pin. 1/4" diameter, 1-5/8" long.
