I am trying to finish up this last piece of the electrical set up. I am trying to put in the turn signal unit on my 51 Commander with Automatic. I purchased a unit a little over a year ago which is the first two pictures. It has 52 Comm written on the tag. The unit itself is very nice and complete. It works fine. However it does not have the other half cover. I posted something before and some guys said they may have the cover. This unit and cover does not match what is in the parts book.

The other unit, pics 3-5, I have matches the parts book and is complete but as you can see it needs a new arm and knob. So I am reaching out to see it I can find a cover for the first unit or an arm for the second unit.
Thanks,
Jim

Hard to tell from your photos, but the first switch housing looks like the one used on the low-end 51s with the skinny steering column tube.

I think the switch itself is the same. You should be able to use the housing halves from the second switch on the first one.

I thought of that and looked it over. The first signal attaches to the housing horizontally and the second attaches vertically. They will not interchange.

I wonder if the first one was for a standard shift, where the steering tube and shift tube were separate, and the second is for an automatic, with a single steering/shift tube.
Speculation on my part, as I don't know.

The first one is for a 52. You can tell by the diecast turn signal lever and the non-metallic grey color. The second one looks like it is from a 50 as it only has five wires. That is for the separate rear turn signal lamp. The 51 and newer should have six wires because the brake light and rear turn signal use the same filament.

They are both for the "fat" steering column and neither of then are from the skinny column.

The 51 and newer should have seven wires because the brake light and rear turn signal use the same filament.

Thanks Roy, I couldn't tell from the angle of the photos.

The second one came off of a 51 Champion with an Auto. It actually has six wires. One was hiding in the picture. I am turn trying to get one of them to work. They both work electrically. The 52 is missing the half cover and the 51 needs the arm and knob. Looking to see if I can find something to make this work.

If they both have six wires, either one should work electrically. The challenge will be mounting the case and finding the complete case. The arm and knob for the 51 should be the same for all 50-51 turn signal switches.

So will the 52 signal work mechanically with the 51 column? Meaning will the auto cancel work? It looks different than the 51 mechanism.

It looks like the copper disks that ride on the column are missing from the 52 switch. Have you looked at the chassis parts catalog to see the differences between the two years?

Edit: I just looked in the 51-54 chassis parts catalog. The parts catalog lists a different number for 51 and 52 turn signal switches, but the steering post that has the cancelling nub on it is the same part number for 51 and 52.

The illustration in the parts book shows the copper disks on both 51 and 52 switches, which makes sense because the cancelling nub is the same for both years.

It looks like neither switch you have is complete enough to do the job. Personally, I would repair the 51 switch. The handle from another 51 will fit and so should the 50 handle, although I did not pull the 50 catalog to confirm that.

OK found the info needed here.

I "THOUGHT" like most of you that:

(1) The Huge Automatic Column Jacket would have a different Turn Signal Base and Cover than the Std. Trans. with a tiny Jacket.

(2) The 1951 is Different than the 1952.

BOTH Wrong! :ohmy:

As usual the 1951 to 1954 Studebaker Chassis Parts Catalog tells us what we do not understand.

The ONLY Difference in these Covers & Bases as far as '51 and '52 are concerned, is that the C1, F1, W1, and Q4 Champion "Customs" used a different Base and Cover: 519967P & 519968P than ALL other Trim Levels.

The '51 & '52: Champion, Commander, Std., Auto, all "Other" higher level Body Types use the 530593P Base and 530594P Cover.

I am assuming that with those Low Part Numbers, these '51 Champion Custom models probably use the '47-'50 Units.

I am wondering however if Jim has attempted mounting this unit to the CAR Yet, that should tell if the Switch & Base is a C1 Body Type or the Cover is, because ONE will be wrong.

I have placed it on the column and the holes line up. I have not hooked it up because there is a manual box on the column. I took it off but not disconnected the wires yet.
After looking at the 51 switch the fiber disk is cracked and will need epoxy to hold it together so I do not know if it will work. So I could use another 51 internal switch mechanism or a parts one to replace the fiber section. When you look at the steering column it has nubs(like cubes) sticking out at 180degress(opposite). The 51 has wheels that go along the column to click it off and it looks like the 52 has a fork the gets clicked up or down. If the column is the same it seems it should work. I will take the plung at cuts the wires and place the 52 on.

A "Manual Box on the Column"?
Does that mean that we have been trying to figure out how to rig a Automatic Column and yours is a Manual Trans. that could be for a Champion Custom? And not correct for your Automatic CAR? :confused:

If it is a Aftermarket Manual NO Cancel Turn Signal Switch, THAT needs to be GONE before you can do ANYTHING!

No, I am not making myself clear. It had this turn signal box on it. Yes, Jim has now cut the wires and pulled it out and bolted the 52 signal in.:D It does seem to cancel but the left signal does not stay down well. Maybe an adjustment. If this will work hopefully I can find the correct cover. I get frustrated because the 51 switch would have worked except for the arm which was rusted in the hole. The arm is out but I cracked the fiber disc but have since used epoxy on it. PC7 epoxy, good stuff.
