A few hours ago I was going to ask for hints on removing a reluctant steering wheel, but I have managed the task, so am posting some information.
After removing the the nut and security washer underneath it, I tried a 2 jaw bearing puller with the jaws going between the first pair of holes in the steering wheel arms. That was unsuccessful as my puller kept tipping over. Then I found the steering wheel shaft could be pulled vertically upwards about 1 cm. This allowed me to support the steering wheel in that position, and using the largest pin punch that would fit inside the half wound on nut to give some sharp hits on the shaft. After about 5 good hits I thought I was not succeeding, but when I tried turning the steering wheel hard against full lock I noticed there was now some play in the steering wheel on the shaft. More wiggling and lifting upwards by hand I soon had a loose steering wheel in my hand.
The steering wheel attaches onto a taper on the shaft. There is also a slot cut in the taper to take a woodruff key. The slot for the woodruff key on the steering wheel itself is not cut all the way to the top. My key has a slight bit of play in the steering wheel slot.
Attached are photos showing a close up of the steering wheel hub, a photo on the taper and thread of the top of the steering shaft, and a photo of the nut, the washer, the woodruff key and the collar that attaches on the shaft below the steering wheel.
Well done Jon I tried with one a few years ago, had it in my press and had to give up because the only thing that was going to happen was a broken wheel.
