'Electric wiper motors..again
I have done a search of the forum and haven't found anyone that has converted a stepdown vacuum wiper motor to 12 volt electric. There has been references of the late Clay Hannah, but I don't see any new ads in the new WTN. Perhaps I missed one? Anyway..I don't want to have to reinvent the wheel .It would be nice to get of on the right foot at least with the right motor to look for in a salvage yard or an address of someone that already has a kit put together... By the way...it's raining here again..:D

Not to raise an old argument, but have you tried rejuvenating your vacuum wipers, at least temporarily until you find an electric conversion? Otherwise, when it rains, "a Hudson meet is a terrible thing to miss." Mine work tolerably well in the rain, with an accessory vacuum booster. Though of course nothing can beat an electric for dependability.0

Jon,
Yep, tried all the tricks. Mine work marginally. rebuilt by Ficken a year ago and were useable. I tried a double action pump, but for some reason it didn't make much difference and then it sprung a fuel leak.Probably bad to begin with although touted to be "rebuilt". I put a new AMC single action pump on (actually three of 'em until i got a good one). I could get along if I hadn't put the new really low number rear end gear in. Now in OD the vacuum isn't enough to work the wipers at 70 MPH. The cruise control has enough vacuum to hold, but the wipers are a pain. I use Rainex to GREAT advantage..Yea I know... slow down. Not so easy to do here in Fl on I-95 where 70 IS slow!0 -
check back chat again... Patrick in OK ... posted the fellas name that bought out the Hanna stuff and the engineering to facilitate new builds. At this time I donot remember the name but I believe it is a HET Club member living in western OK.

Sorry, but you'll have to find that wiper info on you own from another source. Not to sound like a jerk, but I will have no dealings with the individual that does those conversions in OK, and will not help him advertise his product. Good luck.0

I Was In A Salvage Yard Several Years Back And The Owner Was Telling Me He Had Used A Volkswagon Bug Wiper Motor To Replace The Vac Wiper Motor On His Stepdown,but I Didn't See What It Looked Like.i Was Busy Trying To Find A Trim Piece.0

I don't have personal experience with these units, but it looks like a good product.

Sometimes in our frustrations little things get overlooked. Even a small amount of Binding in the linkage makes a BIG differance. Try to get it "free' at both ends of the stroke. If your running off a "T" that's a no-no. Either make it BIG or seperate them,you can tap a new hole. You can also drill out fittings to increase supply. The bigger your supply line right up to the wipers the more vacume you get at the wipers. You get far more vacume off the manifold than the carb.0

Any of the conversion units I have seen use 12 volt motors. They will run on 6 volts, but you get faster wiping action from a vacuum motor.0

Jon, Care to say more about your 'accessory vacuum booster' ?
Thanks0 -
SuperDave,
I have electric wipers on my 52 Hornet, but I didn't install them. They were on it when I got it from my uncle a few years back. I would be glad to take some pictures of the motor if you think it would help. I can look for parts nos. also. My uncle is deceased, so he won't be able to give us much information
on this.
Let me know,

I remember, there was a tech session at Salt lake City National about converting 6 volt vw motor, but I don't have any details on it. It looked like an easy conversion, if anyone has details of it.0 -
Seems like I heard somewhere that a '57 Chev motor was a bolt-in swap, but you had to adapt the linkage to the Hudson cable system. Is anyone else having the same hallucination?0
-
Also Studebaker and Chrysler products had electric wipers , standard equip I think, as far back as 1940. Don't know how easy they'd be to convert to Hudsons but it's something to consider.0

Try Newport Engineering I think they have them . Hudson Dave:D0

I was supposed to send these to New Zealand (or was it Austrialia?). I have 4 of these. Old VW 6 volt motors. My computer crashed and I lost all my emails. I then put the motors under a box in the garage and forgot about 'em. Anyway, I never really tried to see if I could make them work in a stepdown. If anyone wants to try, I'll send one to you for $10 plus shipping.

Yes, a picture could be very helpful. Mostly how the linkage is connected. All the 12 volt wiper motors I have seen have a full circle rotation. I would like to see how that is converted to a back and forth motion. I have sketch I made, but rather than to have to cut and try.. I'd rather take short cut this time. The R&P steering was character builder!I don't want to go through that again..LOL

Delvin Albers is the guy in OK that took over Clay Hannah's wiper motor conversions. I bought my electric motor from him while vacationing in Ok back in the summer. He seemed like a nice enough fellow, even though all he does is make them, he cannot offer any technical help. He's in the HET directory.0 -

I've got a Newport kit on my '49, and it is a great product. I sent them my old pump so they could fit up the brackets onto the new one (and they of course returned my old pump), and they bolt up as clean and simple as can be. Uses the stock bracket off the firewall, and of course the stock cable drives. The Newport unit is not as big and cumbersome as some of the other ones I've seen. They work great too. The only problem I personally had was the delay type switch I bought with it doesn't fit into the space available on my '49, so I just used the plain, two speed switch. I put a Hudson knob on the it, of course.
Now I never have to worry about getting caught in a rain storm wishing I had better wipers.....and it HAS happened.0 -
If you have a 12 volt system the 57 chevy unit will adapt to the hudson with a little work. The chevy unit will bolt to the existing bracket, but you will have to remove the 1/2"X1&1/2" adapter to the wiper drive cables from the hudson vacuum motor and fasten it to the chevy unit including a 1/4" spacer. The chevy electric unit is cable actuated, same as the hudson vacuum motor. The electric wiper motor used in the 57 may have been the same used in chevy trucks until 59, I'm not entirely sure. Also you might look at pontiac from the middle 50's, buick was different and cadillac had some sort of cable drive of its own. I'll try to get some pictures of what I'm describing posted.

Here are a couple of pictures of the wiper motor in my Hornet. Sorry about the poor quality of picture. Other than "Made in the U.S.A." I couldn't find any identifying markings on the motor. It is 12 volt. I hope this helps a little. If you need any pictures from a different angle, I can try tomorrow.

Could you use a 8 volt battery With a 12 volt wiper moter, Would they move faster? Just a thought. Thanks John drivergo20

A 49 Hudson "custom" just showed up on eBay.

One of the pictures clearly shows a 55-57 chevy electric wiper motor installed in place of the vacume motor.
I posted the picture below along with a picture of one of those motors....
And the beat goes on.....LOL

FYI
As detailed in a previous Thread I have converted my '37 & '47 Hudson's to Electric wipers using motors from JC Whitney and sense a need for Stepdown conversion's. So I took a look at my '53 Hornet (which I only drive a couple times a yr) and noticed the JC Whitney Motor may be even easier to install in a Stepdown than in the 30's & 40's Hudson if a person was least bit mechanically inclined.
Stepdown's have plenty of room without the cowl recess to deal with and the 'control cable' could be utilized to turn the electric wiper Mtr's rear Knob On & Off, however, I would wire through an Intermittent switch to vary the speed then Fuse.
Actually, even the original firewall bracket could be utilized by bolting an 1/8 X 1' pc flat steel across the bracket drilling a 3/8" center hole for the Electric Mtr Mounting 'Stud'. Regarding Linkage, the Vacume Mtr Link Arm 'tack weld' could be easily ground off then the 'Arm' fitted onto the electric Mtr shaft. I have both ground/filed fit the electric Mtr shaft and threaded another shaft. Either way will work.
There is a 6V Mtr available listed for '41 Chevy that appears Identical to the 12V Mtr except for an additional mounting nubin which would only require drilling a second hole in the strap bracket
Additionally, The Electric Mtr's thin outter 'Mounting Stud' outside of the shaft requires shortening to slightly longer than the vacume mtr shaft because of the nut now required on the linkage arm. Shorting the outter Stud can be done by hacksawing 360degrees or with a tubing cutter. Of course the inner 'Motor shaft' needs shortened too.
I have not done a Stepdown conversion and have no need to . I only wrote on my experience and observation to encourage someone to try the conversion.....

As per an earlier Thread I have converted '30's & '40's Hudson's to Electric Wipers using JC Whitney Motors. I only drive my '53 a couple times a yr and no need for electric wipers but took a look at the possibility after sensing the Interest. It appears Stepdown's would be easier to convert than the earlier Hudson's.
Stepdown's have a lot of room without the cowl recess pocket to deal with. A flat pc of steel could be bolted across the orig bracket then a 3/8 center mounting hole for electric Mtr drilled. The Contol cable could turn on/off the Knob on the rear of the Mtr, but i recommend wiring thru an Intermittent Switch.
The Vacume ARM can be easily ground off the vacume Mtr shaft then re attached to the electric Mtr by either threading the Shaft & Arm or file fittting.
The Electric Mtr has an internal shaft and external mounting hollow Stud and both need shortened. I used a hacksaw going 360 around the thin outter Stud.
Jc Whitney has a 6V Motor listed under Chevy that appears identical except has an additional mounting point requiring another bolt.
I wrote after my observations and experiences from the earlier installs to encourage someone to try the conversion if they are the least bit mechanically inclined..

I have the Clay Hannah electric wiper conversion that I installed in Queenie. My understanding was that it was a maritime motor that worked in 6v, 12v & 24v. It is a neat conversion and I thought that a club member had taken over providing these after Mr. Hannah died? Unfortunately I have lost the documentation that came with it, so I really can't say much about it, except that it beats the vacuum wipers by a long shot. I came up the continental divide in a monsoon on my way back from the Nashville, national and that is when I decided that vacuum wipers were a joke. They would only work when I let off of the gas which I wasn't real interested in doing. By the time we got off of the hwy in Gallup, NM I felt like I was driving in an aquarium!!!0
