Has anyone rebuilt the 1917 through 1927 open car door latches. It looks pretty simple to open them up but how do you re-seal them, and where do I get new springs?
Fred, if you can send me a picture of your spring, I have a lot of different ones. I've rebuilt early locks but not later ones.
I seem to remember some of the Model A springs fit that are available at Snyders. I know I had to replace ne on the coupe.
Really simple to open them up, sandblast and repaint, then reseal them. The springs are simple coil springs that can be bought at your local hardware store. To reassemble, push the two tabs at the end of the spring holder bracket into the latch, then use a pair of pliers or c clamp to latch the remaining tab in place, then tack weld the tab to keep everything in place.
Langs has a spring kit for the 26-27s.
When disassembling the latches I carefully mounted the latches in a vise and used a chisel to move the braded tabs up in to a upright position. You don't have to remove the braded metal. There isn't much of the tab to straighten. Just be careful.
The latch can then be opened up to repair it.
Put the latch back together and rebrad the tab.
That's how I did it.
Here is a couple of pictures.
And I used to take NOS latches to swap meets and could not get $5.00 for one??????/
If you have a Right Rear for a 25 Touring, I'll take one. Will need one when I cut-in the left front door.
Fred when repairing the latches I have also found that sanding and smoothing the inside surfaces of the moving parts and where they slide makes a real difference on the action of the latches.
If you have an Ace hardware store in your area they have some springs that are pretty much identical to the ones that's used in the latch.
I do have a few good latches but without taking them apart how do I determine the spring sizes.
Does anyone know what the original spring sizes are?
I guess I could take apart a good latch and hope that the springs are not fatigued then measure those but I hate to mess with a good one.
Boy I wish I could have run into you Dan as I have looked for these for years and still have a hard time finding good ones.
