Re: Replace existing Shifter for a Center Console
Jake,
The mechanical assembly of steering systems usually is composed of piece parts, two of which would be the outer housing (with internal bearings) which mounts to the dashboard of the boat and the other the steering shaft upon which the steering wheel and steering mechanism is mounted.
The shaft is manufactured as a single element so at some point in time the steering mechanism up under the dash is attached to it, and then it is inserted into the housing mentioned and the last thing would be mounting of the wheel.
On plastic wheels, there is just a pin which is inserted into a slot on the under side of the wheel. On metallic or more sophisticated wheels, there is usually a splined interconnect (like you would find in your car) consisting of 10 or so teeth. On both types, the steering shaft is threaded and a nut locks the wheel in place.
There is usually a cap on the center of the wheel which can be removed, exposing the nut. The cap could be just pressure fitted, may have plastic spring clips, may have a metallic retainer ring, or may have a set screw on the side of the wheel to hold it in place. A wheel puller is usually required to remove the wheel. Sometimes I have put my legs up under the wheel to help in applying pressure to the wheel during removal. A good penetrating oil surely helps. Also, a smart smack with a hammer certainly helps but don't ding up the threads. Use a brass hammer or add a piece of hardwood or something like that to protect the threads. Remember CCW on nut removal.
