1957 Wiper Motor (again)

[Kurt Kjelgaard]

The vacuum wiper motor was the same for 1957 and 1958.
The coupler (or coordinator, depending on the source of information)
fitted to the motor has two version acc. to the Parts Manual.
One version for early 57 cars prior to car no. 2333 (Trico 89100-1) and one version for
later 57 and 58 (Trico 89100-11).
I can, however, find no illustrations to show what the differences are.

Therefore, I would be happy if anybody has pictures of both types to upload here.

Thanks,
Kurt

The firs coordinator was a large black cylinder like you can see on the red car. The second coordinator was much smaller, like on the blue car. The blue car is a '56 Biarritz; I don't remember why I have the small coordinator on this wiper motor.

Hi Roger,
Thanks for the pictures.
I am a little confused, though.

What year is the red car?
Never seen the coordinator in the red car picture.

However, about the second picture - 1956 and early (pre 002333) coordinator
have the same parts number acc. to the Parts Manual so the blue car picture (if original equipped) must show the early version, or?

I am looking for (original) late 57, 58 pictures.

[Roger Zimmermann]

The red car is a 1956 de Ville, it was the original wiper motor (I sold the car years ago). Another picture from my ex '57 Brougham. It seems that the are some differences with the coordinator, but I'm not sure. The car was sold two years ago.
I I wrote, I don't know if I replaced the wiper motor from my '56 Biarritz, it's too long ago.
Maybe other poeple will chime in.
If you are looking at Lincoln or Mark II wipers, you have also that long black cylinder. Confused? Me too!

[Kurt Kjelgaard]

The 57 Brougham coupler/coordinator on the wiper motor looks like what I think is correct for a late 57.

Anyway, that is the one showing up most when you google.

So, maybe the long black one is 56 and early 57, while the one with the heavy rod going down the side in your 57 Brougham is late 57 and 58.

Could the one in the blue car (not the Lincoln) be from a Chevy?

Can others confirm this?

Thanks,

Kurt

Well, Kurt, I doubt it, but when the car came in Switzerland, it was more or less a ruin! Impossible to know what happened before I bought it in 1986. I even don't remember if I replaced the wiper motor. I bought long ago a '56 NOS wiper motor, I'll have a look at it.
Had Chevy cars at that time a windshield washer coordinated with the wiper motor? I know that an electric wiper motor was an option...when Cadillac had not this luxury!

[Kurt Kjelgaard]

At least the electric motors had the coordinator - don't about the vacuum motors.
The pictures I have googled seems to have provisions for the coordinator.
Maybe when the US members wakes up we will get more answers 😎

 Hey Kurt,

 The coordinator was only used if there were a washer unit installed, regardless of the type of wiper motor.
 I did more digging through my parts and found another one that looks like the one I have mounted on my electric motor. One of these did come from a 56 Cadillac, but I don't recall anymore which one it was.

As promised, two pictures from my NOS wiper motor for 1956. The coordinator is solid with the slider as can be seen on the second picture.
The motor has no GM part number; it was sold by Trico and has the designation CPD 1-4.

[Kurt Kjelgaard]

Beautiful NOS part 👍
Is there a Trico part number on the endplate of the coordinator?
Could be 89100-something...

[Roger Zimmermann]

Yes, there is the number 89100-14.
As I did not have my camera yesterday when I was in my store room, I took the box with me. This is why I can write right now that number...
The casting number from the coordinator's body is P-89101-19.
If you need more details, just ask.

[Kurt Kjelgaard]

As I mentioned in the first post, the early version (-56 and early -57) would be 89100-1 and the later (later -57 and -58) 89100-11.
Your 1956 version says 89100-14....now I am even more confused.

About the big, black coordinators - do they have any Trico markings on them?
They do look a little "non-Trico" to me.
Could they be a generic, aftermarket part?

Unfortunately, I cannot answer, the car which had this coordinator is sold since some years. This was an original part to the wiper motor: the '56 shop manual has a picture with that coordinator.

[Kurt Kjelgaard]

Roger,

I have been searching for pictures of motors with the big coordinator
and it looks like this a 1955 thing - so probably carried over in 1956 until the
smaller pot metal version (89100-1) is implemented.

Just a guess.........
