Re: Steering question
I agree with Pete, please get the terminology right if you want accurate answers. I suspect you are trying to remove the bellhousing from the Gimbal ring. If you have already removed the drive, undone the nut that holds the steering cable to the guide tube, removed the split pin from the pin that holds the end of the steering cable in the tiller and pulled the steering cable ALL THE WAY OUT of the guide tube, then the steering wheel should turn effortlessly. If not, the steering cable or helm unit has a problem. With the steering cable COMPLETELY removed the gimbal ring can sometimes be quite stiff, usually due to the bellows resisting your efforts, but it should move, and then 'spring' back to the straight ahead position. I usually wedge it with a chunk of lumber so the hinge pin remains accessible, remove the pin and lumber, chock the other side, Bob's your uncle....
This description assumes you have a later model power steering. If you have an early model engine, then you may have a drag link between the end of the steering cable and the tiller arm. If that's the case, remove the split pins holding the drag link in and remove the drag link before pulling the steering cable out.
If you have power steering and the power steering unit is still attached to the tiller arm, that WILL stop the gimbal ring from moving....
It would have been a whole lot easy if you had given us a model, year, serial number in the first post....
