The Stovebolt Site Forums The Shop Area The Electrical Bay Guide D2-53 turn signal switch

I picked up a spare D2-53 guide turnsignal housing at a swap meet. The price was right and I was glad to have a backup. It turns out the truck housing and the car housing are different.
Here is the difference:
Car-
Housing-544125
Mechanism-5944865
Mechanism where you screw in the turn signal is shorter
Turn signal switch hole is smaller and round

Truck-
Housing-544126
Mechanism-5948512
Mechanism where you screw in the turn signal switch is longer
Turn signal switch hole is larger and taller

1) The truck housing is egg shaped on the side where the hole is. Not so on the car one as it is perfectly round. Is it possible that my housing was damaged at some point or is this supposed to be that way.

2) Both turn signals have a lot of play around the column. Was there ever some sort of shim in there it keep the housing from moving around? Part of the reason I am doing this work is because my turn signal switch moves a quarter of the way around the column in both directions when I use it.

No one?

There should be a tapered nut that is forced against the column when it's screw is tightened.

Thanks Cletis, I have one of those wedges but it doesn't seem to be making up the space. The previous owner fashioned a shim out of a copper.

is this for the TF truck? a factory unit? if so the wedges in the factory units get worn from years of slipping, but they're available repro and should fix the problem if in the correct position and tight

Thanks Bill, I got to work on this before seeing your response.

I did some looking around and noticed a small channel at 12:00 on the housing and a corresponding metal roll on the column. After years of too much play as a result of a bad block they wore grooves into each other. I fashioned a channel shim out of some scrap metal and eased it into the channel in the turn signal housing.

The channel shim now holds the housing in place on the steering column roll. This shim also stands the housing off of the column to make up the difference the old block wasn't able to make up. The whole this is pretty happy now. At some point I'll throw in a new block just for better measure.
