I got caught out in the rain the other day and decided to get electric wipers and ditch the vacuum operated type. As with most of my adventures with the 46, I don't have a clue where to look or what to look for. Has anybody here swapped to electric and what do yall recommend?

Ive been looking for some also. I know that disassembly of the original chain from each transmission is impossible. So if you want to use your originals and they need to be re-chromed, they have to be done with everything intact, chain & all!
They have conversion kits where the motor fits on your originals from around $200. there was an article on the internet on a guy who did make his own bracket & bought a wiper motor for $20.
Sounds like a good project, Im guessing a lot of time.

Thanks!

Newport Engineering is a bolt-in replacement for the vacuum wipers. Connects up to all the stock mechanicals. I've had their 2-speed motor in my '46 for 15 years and never a problem. I believe they now have an motor with an intermittent setting. Specialty Power Windows has a cable operated system. A little harder to install but a friend with a '41 Chevy loves his. Both are a tad pricey but well worth the change.

Ok, I looked into the electric conversion and found out that I can't use my original A.M. radio if swapping over. So, that set me on the path of trying to get my vacuum wipers working better. Some of the ideas/suggestions were an accumulator in line with the vacuum hose, an electric vacuum pump to power the wipers, or changing out the mechanical fuel pump to one that a vacuum pump built in. All of the people I talked with had NO experience with vacuum wipers but each one thought they had the perfect fix. Any ideas on the suggestions? I was hoping to drive the 46 down to South Louisiana, but I will definitely need a good wiper system to drive there.

I grew up with vacuum wipers, and would be the first to say that the technology definitely has its shortcomings. A conversion to electric would always be my first choice, but I haven't until today heard of a situation where this was incompatible with a factory radio.

If you must keep the vacuum system for whatever reason, the combination fuel/vacuum pump is a patch that offers only a minimal performance improvement. IMO, it's not good enough for a car which is to be regularly driven in the real world.

A standalone electric vacuum pump is a much better choice and would be my preferred solution if I had to keep the vacuum wipers. Now with that said, the electric pump is not a fix for a vacuum motor which is presently working less than optimally.

Do your wipers operate satisfactorily when the engine is idling? If yes, go ahead with the electric pump and you should be done. If no, then the vacuum motor must be overhauled and restored to as-new performance. A search will bring up specialty shops which offer this service. If you would rather DIY, parts kits with instructions are also available. Google is your friend here.

Ray, The size and location of the original radio is the problem. I have an original 5 tube radio that works and just for the " I've got a 70 year old radio that WORKS!" bragging rights, I'd like to keep it.
I've found a vacuum pump online, but all it says is it is for a Ford 250 and gives a range of years, but doesn't give the application, or the psi it pulls. Right now, at idle, I have a 18 psi vacuum and the wipers work great. The wiper motor itself looks to be recently overhauled, ie, nice and clean and "tight".
What do you think of the canister idea? Like maybe a gallon paint can?

Ford vacuum pumps that are belt driven like the one on the diesels usually pull around 21 inches of vacuum---some of the cars in the 70's used a can for a vacuum container--might try that

Canisters are fine for power brakes but useless for wipers because of the airflow volume through the vacuum motor. Remember, a PB booster doesn't flow anything. It is blind, just like the vacuum advance on a distributor.

Is the Ford pump electric or mechanically driven from the engine? If electric, is it 6V or 12V? I assume your car is still running on 6V if you have the stock radio.

It says 12 volt electric. The car was converted to 12 volts but I use a resister to get it down to 6 volts for the radio and heater motor

Jack, sorry to poop on your party, but the pumps you linked to appear to be for power brakes rather than wipers. Consequently, they could very likely have the same flow rate issue I mentioned earlier regarding canisters.

I just found that out. I got the one from AutoZone, hooked 12 volts to it and realized there was not the volume I needed. Took it back. Oh well, still looking!

Scratch the canister idea, too. Didn't work. Looks like I'll either have working windshield wipers (electric) or a working original radio.

Jack, how about one like this?
http://www.ebay.com/itm/Trico-Electro-Vac -Vacuum-P...

Not necessarily this particular one, of course. Ideally, you would find one which you know is in working condition. However, this is definitely the type of pump you want. It was made for vacuum wipers.

If you are more adventurous, you might want to consider one like this if you can devise a way to mount it and drive it from the engine. I presume the stock setup had some way of clutching it so it didn't have to run all the time. You could also drive it with a 12V motor.

Ray, Those look like they would do the trick, all right. However, I am an impulse type of person and after the two "failures" I went ahead and removed the radio and ordered an electric wiper motor from Newport. I have a AM, FM, CD, Bluetooth, etc. do everything radio. I should be able to fit it in the existing radio hole with minor modifications. The old radio is self-contained, with built in speaker so I'll just hook up an antennae and a six volt power supply and use it in my shop.

Linkage and stuff are in good shape. Actually, the whole system looks to be in great shape but like I said, the vacuum design just don't quite cut it, no matter how good a shape it's in.
Hopefully, this will sort out my wiper problem then on to something else. Seems there is always something to do on the 46.

I got the electric wiper motor in and am really happy with it. Keeps up the wiping speed no matter if I accelerate or not. I would put this mod right up there with disk brakes for safety.

Has anyone considered using a stepper motors, and driving them with a microcontroller? It would be easy to control speed and angle. Plus they are used in higher torque applications like as stage motor on CNC mills. Plus they don't take up tons of space. Might be ideal for this application.
