Technical 1939 Plymouth Door Regulators Help

Does anyone have a diagram for the factory installation of 39 Plymouth coupe door glass regulators. I am pretty well stumped after trying numerous ways to install these things. Unfortunately the doors were bare when I got them so I have no initial clue. Thanks Joe

 

If there anything lik the regulators for a '37 Dodge, I can tell you there a pain in the ass to install. I have taken them in and out of Dads coupe more then once. every time i have to re learn how to put them back in.

 

They are the same. And I don't know which one is which. I have tried all the different scenarios and only get so close

 

Might find some help at the vintage Power Wagon web sites. Dodge used the 39-47 truck cab from 39 into the mid 60s on the military trucks. I would suspect that with the military following those trucks have, parts, pieces, and pictures would be easier to find.

 

Does your regulator looks like this? This one is pictured right side up.

 

I have a 40 Chrysler Shop Manual that shows how to R&R the window regulators.
(I had to use it to get the darn things apart; it's not the easiest thing to do)
The guide may be close enough to the 39 Plymouth to be of some use.
Of course the task is made much easier by sticking one's tongue out on the respective side; i.e Left/Driver's side: tongue to Left. Right side/passenger side; tongue to Right.
And gloves are recommended.
PM me and I can send the 8 pages in jpg files if you'd like.

 

My regulator is different then the one pictured. I think that is for doors with a vent window

 

Maybe you could post a picture of your regulator and someone here can help you figure out which way it goes in and how it might attach to the door frame.

I have messed with my share of window regulators in old Mopars plenty of times over the years. They include a 35 Dodge sedan, a 39 Plymouth coupe, a 39 Dodge pickup, and several 40s & 50s Dodge and Plymouth cars and trucks. Given the vast number of them, and the years that may have passed since having my hands on them, remembering which regulators were in which vehicle is a lost cause, but seeing the regulator can bring back a lot of memory. There are 2 primary different operations a window lift can operate. Either the crank section is stationary on the inner door frame (like the one posted above), and the lift arm swings to the side, or there is an "X" bar with the crank section stationary and at least one (but often 2) of the "X" legs are also stationary and the other part of the "X" lifts the window. The "X" nearly always has rollers set in slide channels. There are also regulator systems that combined both methods listed above. Pictures of what you have can help a lot.

For the record, not many Mopars had crank open vent windows until much later. a crank open vent window has to have a 90 degree turn between the crank handle and the mechanism because the function operates at a 90 degree different direction. Door windows go up and down, vent windows pivot right or left (or open and close to the side).

 

I wasn't aware these cars could be had without vent windows, but im no expert. I wonder if who ever chopped the roof was also converting the doors to a one peace windows with a different regulator? Is there a chance the regulators are not correct for the car?

 

I took the regulators out of a stock coupe a while ago. I should have taken a video. I will take some pictures when I get through COVID.

 

I assumed he was thinking about the GM style crank open vent windows.

If his car was chopped, anything could have been done. My 48 Plymouth coupe has the window regulators from a modern Dodge in it, all the original stuff was rusted into one piece.

All of the Mopar vent windows were push open and pull closed unless it was the real high end Imperials. Many GM cars had crank open vent windows from as early as the mid 30s as in grab the window crank for the vent window and crank it open or closed.

 

I have a 37 plymouth 2dr sedan. If your car doesn't have vent windows it probably has smokers glass. The windows come straight back about a 1 1/2" before they start to come down.
To help figure out which reg is the right and left you could put them in a vice with the side that bolts to the car facing you and roll the reg up and down. Theres a big hook that hits a pin (the pin is on the glass channel and the hook is part of the reg) as you get close to the top of the glass travel. With the mounting surface facing you the drivers side glass channel should go to your right. And the passenger side should go to your left with the mounting surface facing you in the vice.
I hope this helps.
These smokers glass window regs were probably in the top 5 hardest things of this car for me to get working correctly.
Thanks Mike

 

I appreciate all the info and the jpg from Gatz. When I got this car it had the vent windows with a lot of stuff missing. I took the regulators for non vent windows from a junk car. I marked them with a marker but thought I got them wrong because of the difficulty. So now with all this info I think I can work it out. The chop just really affects the glass size which after two patterns I am close. The chop gets kind of odd at the front with the glass curve so I had to adjust so it works. Thanks for the help I will update once I get back to it after getting over this freaking COVID. Joe

 

I'm No help , there is a 40 Ply coupe in my possession but stored in 40 ft container far in back , All the 39-41
I have seen had vent windows , Not to knowledgeable of Mopar ,
Any one with Hollander interchange books ?? Is there a web sites for Pre WWII MoPar cars/ vehicles ?
I was watching Bullet, afew days ago in car chase @ beginning I spotted what look to be a 40 parked on left facing down hill in up hill chase , many old cars / trucks in the 1968 movie ,
I know No help with your Question

 

Any idea what side this is ?

 

Is that from a 39 Plymouth?
I’d guess it was from the passenger door, as the crank square would be forward with the lift arms being above as it lays in the picture.

 

It is definitely 39 Plymouth Coupe. I took it out myself from a junker. I wish I would have taken the doors off and kept intact. Here is that regulator rolls up to the right and down to the left. Seems it is the passenger side.

 

When I took out the window regulators of the '40 Chrysler and disassembled then to clean them up, I was very intrigued by the clever design of the 2-way "clutch" that Chrysler engineers came up with.
I'm sure it had been used previously to 1940; and after for that matter, across the Chrysler product lines.






The crank handle would be fastened to the crank square at the right in the above pic.
The coiled spring shown bears tightly inside the stamped housing with 3 holes.
Riding inside the spring is an inner piece staked onto the crank square, with 2 ears that are near the tangs of the spring.
When the crank is turned a certain direction, one ear of the inner piece causes the coiled spring to unwind inwardly allowing the crank square to rotate with ease and in turn rotating the reactor/gear to raise/lower the window, usually with the help of a second heavier coiled spring attached to one of the arms to help overcome the weight of the window assembly itself.
When the crank is NOT being rotated, the spring opens up to bear against the stamped piece once again.
This prevents the window from creeping down (or up for that matter)
The spring acts in both directions so that it keeps the window stationary in any position.

 

Chevy used that style of clutch for decades...I wonder when it was invented?

 

I'm building a '40 and about to install mine. I found this guy on YouTube doing a detailed how-to. If your '39 is like the '40, this should be a huge help. Incidentally I put Ford power window motors on my Plymouth mechanisms. Gears mesh perfectly. There is a slight bump in the upholstered panel, not bad.
