Turn signal cam
« on: May 03, 2024, 12:31:50 PM »
Ok, after centering the new gear, the steering wheel, and getting a shop to align the wheels, my turn signal cam is off a bit - when I turn right it clicks off too early, but when I turn left it clicks off way too late...any ideas?  Can I pull the hub and adjust it?

...and it's the stock rally wheel with the six screw attachments...

If nobody else responds I’ll try to take apart the spare column I have. It’s been a few years since I pulled one apart and I can’t remember how the cancelling cam is oriented or if it can be repositioned.

No worries, I can pull mine - I was just being lazy to see if anyone could remember replacing their cam...I'll probably just pull the hub and be 100% sure the cam isn't damaged; it is about 20 years old...

It may be the cam is bad?  I have taken apart a few columns and do not remember there being any adjustment. It seems to me everything locks into place. There may be a millimeter side to side but I dont think there is any alignment or adjustment built into them for fine tuning.

I think you are correct about the inability to adjust; I need to check to make sure I didn't damage the cam during my new steering gear adventure...it's even possible I misaligned the hub a bit, which will suck because I'll have to re-straighten the steering wheel if I made that boneheaded mistake!

Unfortunately I need to replace mine as well. I had rebuilt/restored the column for my 79 a few years ago. I finally got around to putting it in a month or so ago and lo and behold the turn signal stalk moves freely :shock: There is no stop or centre position for it. I dont know what happened to it as I am pretty sure it was ok when I did the initial work. You will probably get to yours before I do mine though.

If I remember right in the 79-81 columns there is a little arm that attaches the stalk to the turn signal switch. It screws in to the switch but only sits in a hole on the stalk side. It probably came out or wasn’t in the right position to start.

 8-) Thanks - I'll check that out when I get back home in a few days!

Sorry man, I was replying to Kerry’s post. As for your issue, if I remember right the horn contact is part of the cancelling cam. The contact protrudes through the lock place and only has a limited range of motion and the lock place can only go on one way followed by the hub which has a hole for the contact but can be adjusted a tooth or two depending on where the cam is in relation to the lock plate. So it might have a little adjustability but I’m thinking like 1/8 of a turn if that.

I finally figured out all the issues, replacing the cancelling cam and realigning the steering wheel properly...that's what I get for not remembering what I did almost 30 years ago!
