Question Inner Horn Contact Scraping Turn Signal Handle

I am attempting to restore the horn system on my recently acquired '69 Z/28 RS. It's obviously not been working for a long time.

Refer to attached picture. In the upper left hand corner, you can see the phillips head screw that attaches the turn signal arm to the turn signal mechanism. The white plastic piece in the center (I'll call it the "inner horn contact plate") rotates with the steering wheel. On the back side, it has a circular contact plate that makes contact with a spring loaded button providing the Horn circuit.

When I pulled the steering wheel, I noticed gold-colored metal shavings lining the inside of the steering column shroud. It turns out that the "inner horn contact plate" is scraping against the turn signal arm and mounting screw. This is a dead short. All of the mountings look tight and correct.

Has anyone seen this problem?

Thanks in advance for any help.

Re: Inner Horn Contact Scraping Turn Signal Handle

You might have the wrong Cancelling cam. The 69's are taller than the 67-68's. Also, there is suppose to be a spring under the cam, it might be missing.

Re: Inner Horn Contact Scraping Turn Signal Handle

First, thanks for the quick responses! This is awesome...

The spring is present and seems to have nice tension pushing the cancelling cam (now I know what it is called!) out toward the steering wheel and away from the turn signal mechanism. You could be right that the problem is the wrong cancelling cam. I'll investigate that next.

Jim, drawings were very, very helpful. Thanks.

Re: Inner Horn Contact Scraping Turn Signal Handle

Quick update: The '69 cancelling cam is different from the 67-68. I found one in the drclassics catalog and ordered it. Awaiting it's arrival...

Mystery solved! It was, indeed, the wrong cancelling cam. New one arrived last evening and installed without problems. The '69 cancelling cam is taller than the 67-68 and clears the turn signal screw.

Everyone, thanks again for your help!
