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.
I would encourage you to inspect and probably change #19 in the drawing. Part# 124035X. There may be a lot of slop where the metal column goes into the plastic part. If you need to replace it be sure to index part #23 and #27 before disassembly. Photo, scribe mark or something. I changed one on a Poulan/AYP last summer and it tightened the steering up a lot.
