Blinker cancel cam
 

I replaced my blinker wiring and cancel cam on my 65 GTO. Now my blinker cancels right at straight ahead in one direction and doesn’t cancel in other direction unless I turn the wheel considerably more than the turn requires.
My question is what is the correct procedure for fixing this ?

Did everything work correctly before? Is your steering wheel centered when driving straight down the street? If your car's front end was aligned with the steering wheel crooked it will make the canceling different turning right from left.

Does it have an aftermarket steering wheel and adapter on it?

Add a picture of the installed cancel cam with the tires in the straight ahead position.

Update with more info
 

I bought the car about 4 years ago. Blinkers worked fine. I did a complete wiring job except for blinkers about 1 year after buying the car. Blinkers still working fine. I never really pay attention to where each direction was canceling at because they were working. They started not canceling about 2 or 3 months ago. I decided to replace the switch and cancel cam. We could not get the new cancel cam to work in one direction so we put the old one back in.
I noticed when we took steering wheel off the horn lug was around the 2 a clock position. The aftermarket steering wheel can only go in one position to align with all mounting holes and horn lug. If we index the horn lug to about the 10 a clock position the cancel cams work in both directions but the steering wheel will not be aligned correctly for straight ahead. I am very confused how this ever worked but I know it did.

Pretty sure I noticed this when I swapped over to aftermarket starring wheel. Grant to be correct.
Hub had the horn contact in different position so when trying to align new hub with cancel cam it got confusing.

It is a Grant aftermarket steering wheel.
How did you correct it?
I am thinking about re drilling the holes in my steering wheel.

My wheel has serval different spots where the wheel can be bolted to the hub, so I got it close. Then I believe I had an alignment done afterwards
and made the steering wheel centered during the alignment. Putting the cancel cam in original position And did alignment ETC after.

Thanks for the info.
I believe I will re-drill my steering wheel.

Where can one purchase this spring seen in the 67 GTO steering wheel diagram? See attachment

Do you have the correct adapter for the year car that you have? When I bought my adapter it came with a spring.

Yep, Grant steering wheel issues........ the standard adaptor has the wrong position for the cancel cam. With the wheel straight ahead, the cancel cam ends up at the 2 o'clock position. The proper position is 10'oclock. I called them up and they sent a different adaptor. I ended up not using it and redrilling the wheel and using the standard adaptor. I posted a lengthy thread years ago related to this issue.

One would think they (Grant) would have figured this out over the years.........

No I have a stock 67 deluxe steering wheel on a 67 GTO. I think a previous owner and one time had an after market steering wheel on this car and now neither the horn or cancel cam work. The horn wires coming off the spokes are cut off. I have the aftermarket part to fix this but as you can see in the diagram there is a spring in the assembly and I do not have this.

Check out this diagram and the spring I have an arrow too

I have 1 if in need send PM
