The model number is 917.270821 and the clip number is 12000029. There is a large pin that holds the steering wheel and gear together at the bottom. There is a clip pin that holds 3 thrust washers on. There was only one washer and the clip came off. I tried to put a thicker washer on but the clip didn't have enough room at the end of the pin. A crow bar wouldn't move the pin out far enough. Any suggestions? Thanks.
