I just got around to replacing my turn signal switch on my 68 with standard column.

I though there was supposed to be both a spring and canceling cam on the steering shaft, but I only have the canceling cam. Do I need to worry about having a missing spring? I'm assuming it's there to put a little pressure on the bearing so that the c-clip isn't taking all the load, but I've never opened up the column before.

If a Delco switch there a left and right cancelling springs. I do not remember on the Boyne switch.

the spring I'm referring to would go over the steering shaft itself, underneath the canceling cam to apply pressure to the bearing (I'm assuming). Jim Shea's guide to replacing the switch mentions removing the canceling cam and a spring, I just didn't have a spring.

The steering wheel was replaced and switch was broken when I bought my bird, just finally getting around to replacing the switch versus hanging my arm out the window...

It's been many years since I replaced my turn signal switch so I can't recall. I looked at the Parts Illustration Book and found this: http://www.thefirstgensite.com/library/partscounter/illustrated/misc/steer1.html

If I am interpreting this right, the tilt wheel has a spring under cancelling cam and the standard over a different cancelling cam.

And... I wonder what percentage of drivers in 2017 know what "hanging my arm out the window" means? Is it even in the states' DMV rule books now? And finally, I wonder if the driverless car software recognizes a hand signal?

Thanks for the pic! I have a similar one but it didn't have the parts tagged.

I don't think anyone paid attention to my hand signals :-). The only people I've seen in the last few years were motorcyclists, but I doubt people paid attention to them either :-)

Drivers nowadays do not pay attention to normal signals on vehicles.

ok, one final question. The press fit bearing in the signal switch housing is pretty gummed up. Anything I should know before cleaning it and re-lubricating?
