Alignment of turn signal cam with steering wheel

[bgrisi]

I had the steering box on my 79 spider replaced in the spring of last year, and since then I have experienced that when I try to engage the left turn signal, it felt blocked from moving into place. I finally have removed the steering wheel and gotten down into the turn signal unit. When I look at the alignment of the pin on the steering wheel that turns the cam, it doesn't seem that it is aligned properly. It seems to me that when the steering wheel is straight, the cogs on the turn signal cam should be situated at the top and bottom of the turn signal assembly. However, when I look at the pin on the steering wheel, the only way that this can be lined up with the cam hole is if the cogs are on the left and right side of the turn signal assembly. This position puts one of the cogs right in between the two spring loaded levers that move upright when the turn signal is put into a left turn or right turn position. This means that the cog gets in the way of my left turn signal being set unless I turn the steering a bit to allow the spring loaded lever to move upright. Does anyone have a picture or diagram of the alignment of this cam relative to the turn signal assembly?

Thanks for any help you can offer, even if it isn't a picture.

And you did not take it right back to them for not aligning the steering box to the steering column or pitman arm correctly because?

You probably need to start reviewing the installation of the box to ensure its lash was adjusted properly and lined up with the bottom of the steering column and pitman along with the tie rod ends centered properly before going too far trying to correct a bad install or alignment via the steering wheel.

Make sure you have exactly the same amount of turns left to right. If not, that needs to be addressed first.

Yes, I had this exact same problem! Only one turn signal would actuate or turn off. felt like there was a mechanical blockage and there was. The return mechanism in the column was jamming the turn signal. The issue is that a PO alignment was done without the steering system at dead center. Thus one tie rod was shortened excessively while the other was lengthened. Get the wheel exactly dead center and then do it and the turn signals will once again line up ok. I marked one steering wheel bolt with a piece of tape to help get the lock-to-lock center determined. On mine, the center of lock-to-lock didn't exactly line up the bolt pattern for the steering wheel, but after finding center, just rotate the steering wheel whichever direction is the shortest to get it (the steering wheel) to center and then do the rods and it will work out.
