Turn signal cancel cam

[Laker]

Where can I get this part? I believe this is what I need as my turn signal will not return to neutral. I’m half deaf so I don’t hear the signal still flashing until the wife mentions it.

I just ordered a replacement switch from Toms; haven't installed it yet.

You can get the cancelling cam for the steering wheel:

Or if the tabs are broken off your turn signal switch, you can replace the whole switch or sometimes find a repair kit to replace just the moving part with the tabs.

So bringing this up again.... I see there are turn signal cancel cams that have one hump and others that have two humps.

Is there a reason for this? Mine turns off on right hand turns only and it's a one hump, so guessing I need the two hump???

Thanks all!

The two hump one will cancel the turn signal sooner as the wheel returns to neutral.

If yours is not cancelling after a left turn, you probably have a broken arm on your turn signal switch.

Two humps were from the factory. One hump is typical aftermarket parts not matching stock.

The 1960's Ford OE turn signal switch has to be one of the "worst ever" designs by any manufacturer.

Back in the late 1960's, it was a daily service department item replaced. The hot Arizona temperature, and the poor design made them fail even when they were still relatively new vehicles.

I had it down to about 10 minutes max, to install.

I used a home made tool made from a 3/16" welding rod, sharpened to a point. Hook the tool's point into a wire end, and push them one at a time down the column. It took longer to go to the parts department and fill out the work order.

Learn something new every day, didn't know the turn signal wasn't completely manual, mine sure is!

 

[DirtDonk]

hah! Yep, probably a lot of owners in your boat. Most of them have broken long ago, and it was up to the PO's to change them. And a lot never bothered...

In my area it was always the cold that got them. Not hot enough for an early death, but after they get old the cold makes up for that longevity when the plastic gets brittle.

I wonder which vehicles had the single cam and which had the double? As mentioned earlier the Broncos had doubles, but maybe the really early Mustangs had singles? Everybody tries to sell Mustang parts as original Bronco parts, but that only works some of the time.

I recall that as well...

Just installed mine yesterday. Plastic cancelling cam is very tight on steering wheel hub. I got mine from Tom's, #3797. Had to use a snap ring pliers to open up the cam so it would fit on the steering wheel hub. Good luck!

I have a 1964-1/2 Mustang that was built in the first three weeks of Mustang production. Double hump cam on the steering wheel.

So much for that theory then!
Maybe they just lost something in the translation between the English and Chinese languages.

call it double hump right haha

 

[jckkys]

It's kind of personal preference. I like the single hump that doesn't cancel in lane changes. Ford got around to fixing the turn signal switch in '78. They last several times as long as the earlier ones and the have a momentary or lane change function.

Well looks like the arm broke, hence the issue. Frankly I couldn't fully understand that article http://www.stratadrome.com/bronco/steering.htm as the pictures aren't clear at all. Regardless I need a new switch, which I just ordered from Nick. FYI I do have a grant wheel... Is the answer to grind down the tabs so they're more like an arrow? I had all that clicking noise previous to the destruction.

 

[omureebe]

Well I'm slowly learning.... I didn't understand how all this worked and re-reading posts I can see the roll pins (now I get the two black "rolled" pins) have the same effect as the cancel cam, and you replace the pins with the cam. Next step is to replace the broken switch, and swap out the pins for the cam and see if that works fine. If not, maybe I'll have to grind down the plastic arms that historically caught the pins.

I had better results with the roll pins than the stock cam on a grant wheel adapter. YRMV. Good luck.

If using the roll pins some, if not all the time you need to tweak/ bend the pins to get the roll pin to arm contact clearence just right ..not enough clearence and the arms break premature ..
