The Stovebolt Site Forums The Shop Area Paint and Body Shop Doors Door relay/lock

I just acquired a 53 3100 that has been 95% fully restored. Just some minor tasks left to complete.

One item, the door locks. It has a keyed lock on the drivers side that works. No key on the pass side.

Neither side locks from inside. The owners manual says that both doors should be able to lock by putting the interior handle in the forward position. But there is only two positions available on both latches.

Is there a different door relay mechanism that has the 3 position (unlatch,latch,lock) than what is installed on my doors?

Are your door latches original style? The lock feature of the interior handles is all done inside of the door latch, not the handle or the relay arm.

Yes, I think original. There is no button on the door or latch. The lock would be activated within the mechanism. Photo added above.

For a '53, it looks like your inner door relay is upside down. Sorry I don't have a clearer picture. Even though the relay looks like it should fit in the indent, it doesn't. Installing it upside down will limit the travel of the relay.

Thanks. I will give that a try. On a related question (and to reconfirm that I wasn’t the restorer 😉)... what do you call the drive bit necessary for those large screws holding the relay in my photo!?! The ones that look like a circle with it’s top and bottom sliced off?

Cuz, I’m going to need to buy one of them. Lol!

I believe that he has an earlier model relay. They were "push forward to open and pull rearward to lock" and did ride in that indent in the door.

I looked at this thread last night and dug out my service manual. There are pics of the door relay mounted in both positions, so that's a bit confusing. I haven't looked at my doors to see which way they're mounted, although my truck is a '51. I'm assuming they changed with the outside door handle change to pushbutton type in '52.

I thought they changed after 1947 due to a safety issue of pushing forward to open the door.

Those are called clutch head screws. You can get a set of 4 different sizes from lots of the vendors or on Amazon. Car parts stores may or may not have them.

Thanks Kevin

MN Smith - you nailed it!

Here’s the after photo...all latch, unlatch and lock functions in working order. Thanks to all!

Your rod is in the right place, the controller is still upside down. Three bolts attach it. The top one, the difficult one.

His "problem" is that he has a '47 relay, however his solution of mounting it upside down will work as long as you don't worry about it being held on by only 2 bolts.

Thought about getting the correct relay online, but they are only held on with two screws as well (the top of the triangle is eliminated). So I made the 47’s work. Thanks
