I had a lot of play in the steering wheel on my 1476. Found it to be the steering quadrant bushing that was wore and allowing the quadrant to lift and twist. Took a lot of soaking and a new 15/16" open end wrench to get the bolt out. I found the bolt used has threads running clear to the head. The bushing was a two part bushing with bronze on the outside with a steel bushing inside. The steel bushing had threads wore into it from the years to turning. When it is put back together I will use a longer bolt without thread to the head so there is no threads inside the bushing. Will cut it to length and apply plenty of grease at the wear points so it will last for 50 years and more. After everything else wears out the steering quadrant will still be tight.
