Oversize Steering Column Pivot Pin

[RussMcB]

My '91 seemed to have excessive play in the steering wheel (more than 1/4" down and to the left). I bought an oversized pin from Marc (http://www.zr1specialist.com/HAT%20W...lumn%20pin.htm).

I'm in the middle of the installation and I have two issues (not with the product):

1) The new oversized pin will not go all the way in. After tapping it with a hammer a bit, it still sticks out 1/8". Should I remove a little metal and try again?

2) A plastic part fell out (see pictures below) and I can't figure out what it is or where it goes. Any thoughts?

Thanks.

call or email Marc ... he checks his email late nite/early AM and he's usually at the shop by 10 AM

This exact same thing happened to me. The part that fell out goes between the turn signal stalk and the number 77 in the diagram. I had the same problem with the over sized pin too, sticking out just a little too much. I did not feel competent to tear down the steering column (which is required to get the plastic piece back in) so wound up taking it to my local Corvette specialist. He said the one over sized pin really wasn't going to fix my problem either. Ultimately, he wound up replacing both parts of the hub with NOS (He had a source. If I can find it I'll post it).

I found the source;

I don't have the phone number though.

Marc's pin worked for me. It does fit w a bit of an edge left.

I'm not finding fault w/ Marc's pin. By itself, it would have taken enough play out of my system to allow the car to pass inspection. But once it was in the hands of a "specialist", it was a case of "in for a penny, in for a pound", so I opted for the "pound".

I think t hat part is for the High/Low beam switch.. been a while since my column was apart

I did the pivot pin on the driver side of the column, I still have play. I have a complete telescopic column that I am really tempted to install and remove the air bag on my 90

Thanks for the responses. Good info.

I emailed Marc and he responded pretty quickly. Regarding the tight new pin fit, he suggested I look to see if the hole is oblong. I'll do that (hopefully tonight) then decide next steps.

Regarding the mysterious plastic piece, he said, "That's the high beam light switch cam. Reach down and move the high beam switch. The way that the rod moves should help you determine how to position the cam.".

This is a "typical earlier Saginaw column" BUT from a Fiero with different key release but all else should do well. Page 26, 43 and 44 are documented pretty well with snapshots showing dimmer actuator orientation. There's scattered others that are very valuable. I've posted this a couple other times and I posted a Corvette one many years ago also that was not as well documented but worked well.

In your FSM see 3F5-8 fig 16 for proper orientation of the dimmer actuator, it's a very minor difference in the end cap fabrication early to later. Make sure the dimmer rod is inserted and dimmer responds appropriately.

It really is an amazing document. Kudos to the author JAZZMAN. What really astounded me as I read through it is the engineering and incredibly complicated parts that go into such a seemingly simple device. Sometimes we forget why GM employs so many fine engineers who make such complexity seem ordinary and operate smoothly for the user. -Bob
