VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Wiper Motor

Does anybody have a good idea for what can be used for a wiper motor on a 1929 closed car. My vacuum motor can not be rebuilt

Just out of curiosity why cannot it be rebuilt other than it is disinagrating, is the case? Just curious becasuse I have the same motor. I have seen them on e-bay before anyway

I will send you a PM about where to repair the vacuum motor.

:vcca:

I should have mentioned that the wiperman said it could not be rebuilt I'm open to ideas

Since the wiper bodies are made out of pot metal, they are usually warped. If so, then the wiper motor cannot be rebuilt.

Some of the warped wipers can be rebult. There are techniques that can take the warp out at least for a while. However there will be no guarantees as the time to warp out of shape again maybe short.

Hello Andy29,
had the same problem with my 31 Chevy. Did try to repair the wiper, am experienced in old church organs with pneumatic systems and vacuum is vacuum, makes no difference between a wiper and an organ. But I had no sucsess because of the pot metal in poor condition.
wiperman said sorry rebuilding is impossible, so I bought about 10 old wipers at ebay.com in hope to be able to fix one working wiper together with all these parts. But before I did begin I found a brand new one with guarantee as well at ebay.com about 90.- USD and I bought it. Had to make some changings on it because it is a big wiper for a truck, but now it is done and it works powerfull and I am happy...
So, dont feel pressure to find one, just search in ebay frequently and soon you will find a possible one in good condition.

Good luck!
Stefan

We are searching e-bay and other places so I see I'm not alone thanks everybody for the help

Andys29,

When I bought my '29 coach a few years ago it came with a bag
of used Trico vacumn wiper motors. One of them fits the half-moon bracket that the '29-'30 wiper motor uses to mount to the header on the outside of the car above the windshield. It fits it perfectly and the vacumn hose connection is in the same general direction as the correct Chevy wiper motor. There are some minor differences in the motors, one being the
non-Chevy motor has an on/off push/pull switch (like Model-A
u-know-whats)on the wiper motor body itself. This could pose a problem, but all you would have to do is leave the switch in the on position and trim it down some. The letters and number on the wiper body in yellow paint (appears factory applied) are: KCX_9 or KGX_9. I have a feeling that this is a
replacement wiper for a Model-A, but I'm not positive. I hope this helps and sorry, but I want to keep this one for myself incase I may need it. For now I'm going to "go on the hunt"
on eBay and see if I can find one like it for you. Bob

Andys29,

On eBay look at item #'s 350152271590 & #360123928330. The first one is an original Model-A Trico with the screw mounted oval cover. The second one is the Trico replacement for the original with the clip on cover. The only difference between the two on eBay and the one I have is the mounting "ears". The ears on the wiper I have are exactly like the original '29-'30 Chevy one. The one's on Greed-Bay (sorry, had to put that in, I don't have Paypal)are longer or deeper
by 3/8ths of an inch?? Distance between the mounting ear holes I bet are the same, but I have no way to check. If they are then maybe the greater length or depth on either of the two eBay wiper ears can be shortened to match the Chevy wiper?!?!
Also, maybe Mr. "Wiper Man" can do some cross checking if he
has any Model-A wiper motors in stock.....good luck. Bob

"Greed-Bay"? That's a good one and oh so accurate too!!!

JYD,

How ya' doing? I've been away from the web site and my '29 coach for a while. Got kind'a frustrated working on the clutch
so I put down everything and walked away. The gas prices were
skyrocketing at the same time so that didn't help any. Things are starting to rust up in my shop so I thought I better get back on it so to speak. Good to see you haven't changed!

Welcome back Captain! Yep, the old dirty mutt is still here and things have been great. Still got the same old fleas though, and this old dog is about due for a bath near the end of this year.

Anyway, glad to see ya back and good luck with your '29.

Captain Harley. I bought a wiper motor for a Model A F0RD on eBay and mounted it on my 28 chevy, later I found a NOS wiper motor for a Chevrolet closed car. The differance that I can see is that the F0RD wiper has the wiper control (on-off) on the top of the wiper motor and the inlet tube is pointing in the opposite direction from the one on the Chevy wiper motor, also the Chevy wiper motor don't have the control on the wiper motor, just a tube to connect the hose to, the Chevy control valve is mounted on the dash. The mounting extensions appear the same to me. I built a half moon shaped mount for the model A motor, then mounted it to the strip above the windshield. I mounted mine a bit high , the exterior visor barely clears the wiper arm. I'll try to get a couple of pictures next week if you need one.

Mr. Mack,

The Trico replacement wiper that I have talked about might be for a Model-A, I don't know for sure. But comparing it to the
two on eBay that I pointed out. It is the exact same except
for the depth/length of the mounting ears. The vacuum inlet
is facing the same side as the original 29-30 Chevy Trico wiper that I have too. Model-A closed cars "I think" might
have run with the wiper motor 'flat side up' as opposed to the
29-30 Chevy wiper that is run 'flat side down'. I know the Model-A manifold vacuum connection is on the right side of the motor. On the wiper mount on/off switch I would just leave it on and use the Chevy dash control for the vacuum line. And, yes, please do post some pics of your wiper mounting set-up. I always like looking at "vintage" Chevy's
and their particulars. Bob

Harley, I think you are right about the length of the mounting ears and yes I did mount the flat side up, probably opposite of what I should have done.

Gentlemen,
I,m new to the restoration world so I joined this organization and have been reading as much as I can on this forum. I soon recogized how dedicated the knowledgeable people are that aswer all the questions. In my ignorance I posted a question a while ago about installing a 33 chevy engine in a 32 coach temporarily while a collected all the original parts for the 32.I very quickly discovered how true most of the guys are to being " correct " on everything down to the screw in the ring that holds the headlight lens in place . I was waiting to hear that the slot needed to be vertical and not horizontal.Having an open mind I know that car collectors have mixed models in there collections. Chevy is my brand of choice and I would sooner fabricate a bracket to manually operate the wiper blade than attach anything to my car associated to ford.
sincerely, Denis

If the motors you have have the KCX-9 number on them you have the correct motor for 30-31 chevys and I think for 29 too

1931Chevy,

The Trico wiper motor I have that I beleive to be a replacement for Model-A's has KC(or G)X_9 in yellow stenciled
paint on the main body. Again, I am not sure if the wiper motor is for a Ford or other make. But, it most definitley was not for a '29-'30 Chevy passenger vehicle. It has an on/off switch on the wiper itself. As far as I know all '29-
'30 Chevy passenger vehicle vacuum wipers were controlled by a switch on the cars dash. I could be wrong, it would not be the first time nor will it be the last either, if I am. Bob

The wiper motor for '29 & '30 were a Trico model Sp. 903A on the closed cars. The replacement (or alternate) was Trico model RSX-2. Later a "K Type" was available as a replacement. The "R.S, Type" can be identified by the two small screws that are used to attach the Trico logo plate and kicker assembly cover to the body. The later K Type had a snap on cover. FYI the RSX-2 is also listed as standard for '27 and as optional for '28

The Model '30-'31 Model A used a KCX-1 and the '31 Chevy a Trico Sp. 956-A or CX9 (screw on cover). Later the KCX-9 (snap on cover) was used. The Model A wiper motors are most easily identified by the thicker round ends on the mounting arms. Those ends are also tapped for machine screws to secure the wiper. While the Chevy wipers have screws that go through the ends to the taped threads on the offsets on the bracket.

Thanks the Wiperman said that the KSX-2 is correct for a 1929 Chevrolet and needs a mounting bracket. He also said that the KCX-1 for a fXXd had the same mount holes spacing but the depth on the part the bolt/stud goes thur would have to be trimmed. I think I stated this right.

The Wiperman is mostly correct except the KSX-2 is a later replacement.

I know he is or has a lot of info that is why he is the Wiperman

Chipper,

Thanks for all the proper nomenclature on the wipers. Important info. for future reference.
