Trunk Lock Cylinder - Separating Barrel from Extension Rod

[kbuhagiar]

Hello Folks,

I am in the process of replacing the trunk lock cylinder on my 1947 Plymouth.

The extension rod on the new replacement is shorter than the one on my old lock, so I need to remove my original and attach it to the new lock. However, I cannot figure out how to remove the collar that holds the extension rod to the lock barrel.

Can anybody help me out?

Thanks in advance for your assistance and support!

It appears that the collar does come off, but I've never figured

how to get it off.

Just tap on the square end of the shaft to force it out of the tubular retainer. There are 2 dimpled depressions on that tubular retainer. Rotate the retainer 90 degrees first if you can get at it, That will make it easier for the handle to come apart easier.

All fruit salad here, but a mix up between apples and oranges:p

OP is talking about the lock cylinder shaft collar.

I believe removal of that would be difficult.

Need to get the correct lock cylinder

You know, I was afraid you were going to say that.

That means the vendor sent me the wrong part AGAIN.

AARGH!!

Pardon me while I go off and simmer in my frustration....

Whoopsie-never mind-does not apply to lock cylinder repairs!

May be a case of door lock vs trunk lock.

I think I learned that lesson already. I bought a trunk lock with keys off ebay for my 40 plymouth sedan door and was assured that it was the same as the door lock ( it's not) the shaft is longer. I needed the door lock, but may be able to make it kinda work by shortening it. What years do the locks interchange if any?

I think the door lock shaft has a tapped hole in the end of it.

The collar can be removed using a file and or a Dremel grinder. I removed mine in order to have handles replated. What I did was to do some grinding in the area of the collar that had been deformed or dented in to the point where with the aid of either pliers or hammer it was possible to remove the collar. The same collars were reinstalled. Should you remove all of the indented area, you still have more than half of the collar remaining which can be reused and dented. There is probably a spring washer next to the collar that you want to save and reuse. You can do it.

Thanks anyway, Mr. Dodge b4ya - I appreciate the effort.

Thank you, Mr. shel_bizzy_48, your picture would seem to confirm that I received a door lock instead of a trunk lock.

Question - The cylinder of the replacement lock rotates 360 degrees - do the door locks operate that way also? Just trying to verify that it is a door lock, as opposed to, perhaps, the wrong year/model of trunk lock.

Thanks in advance.

Mr. suntennis, thanks for the input.

After further review I have decided not to alter the lock assembly.

I will call the vendor on Monday morning and ask him to take the part back and refund my money.

In the meantime, if anyone out there has a replacement trunk lock (and keys) for a 1947 Plymouth for sale, drop me a line!

Ken none of the pictures show the opposite side of the lock but I believe there is a little square piece that is the locking tab that holds that barrel shaped piece over the shaft. Some of it depends on the style of lock. They made a lot of these cars and I have seen 3-4 different styles of lock cylinders.

And here are a few different ones...

Thanks to everyone for all of the information.

Before I forget, does anyone know where I can find the round gasket that goes between the lock cylinder and the trunk handle assembly?

Thanks again.
