Post '55 Chevy OEM electric wiper motor

I've been pulling my hair out, over this one, for quite a while now...

The built 350 in my '53 hardtop is NOT "vacuum wiper friendly." I heard the OEM electric's that came on the 55's would bolt right up and use the existing cable control. I picked one up for a price and WAHLAH! it worked perfect till the power wire came unsoldered from inside the motor, so I tore it down and resoldered it....

Here is the BIG problem - HOW DO I GET THE DAMN THING BACK TOGETHER?

There are no brush retainer holes in the housing. I've studied the thing till I'm blue in the face and, for the life of me, Can't figure out how to keep the brushes out of the way long enough to slide it together far enough to line the brush holders up with the armature. I'm sure there is a trick special tool on the planet somewhere.

Has anybody ever dealt with one of these nasty ol convoluted vintage wiper motors before?

What is it, that I ain't doin' right. Should I just get out the DRILL MOTOR and the paper clips? I hope not.

Get a copy of the 57 Cevy Shop Manual. The information you seek should be there. Make sure it's a 57 Manual as the 55 and 56 books won't have electric wiper information. The elec wiper was a 57 option. It does replace 55-56 vacuums but wasn't available for them until 57.
I love technology.

pasadenahotrod - My first thought, was to take it back to the guy I bought it from and tell him to "stick it." After shoping around a bit though I've found they are real rare. A working example is worth atleast $100, I got mine for $75.. I think I'll go for a 57 manual and try my hand at it, one more time besides, I don't drive the 53 in the rain much anyway. In Oregon, you just never know what the weather'll do...

Maybe you could drill a very small hole thru the casing into the area where the brushes are and insert a paper clip or needle into the hole to hold back the brushes similar to the idea that GM uses on their alternators. I've got a'56 chevy and I have herd people say 'don't open it up", but there must be a way to reassemble it as they do it when you have them rebuilt at an electrical shop.

I'm surprised that those electrics aren't worth more these days. 20 years ago we were scrouging them out of the junkyards and getting $100-150. They have always been rare since not all 57's had them and that's the only year application from the factory. I was just glad my son's 57 BelAir had them. I try to avoid vacuum if possible.
I imagine the reason for no price increase is that you can spend 3-4 times that for a kit setup from various aftermarket car companies now.

Since parts like that are almost unobtainable in holland we use windshieldwiper motors out of farmingvehicles, they are small and most of them have the degree of swing you would need on those 50style cars, just weld on a small plate to hook up to the wiper mechanisme and thats it, most of them are small enough to craft them into the old vacuumhousing so you will keep stockappearence.
just a hint.

Cool

The vacume wiper motor for my 53 chevy is not vacume friendly either. What did you find out about reassembling the replacement wiper moter? I was thinking of going to one of those pump/tank setups for power brakes but using it for the wipers.

bdv - you just might be on to something there.. although, I've never yet seen an electric motor small enough to fit inside an old OEM Vaccume unit, anything's possible..

454 - My power brakes are working great and I've already got the money out for the 55 electric motor or I'd seriously consider going with the electric pump and vaccume canister idea. I've kinda put my electric wiper motor dilemma on the back burner here lately. For lack of any other better Ideas, I think drilling a few brush retainer holes in the motor housing is the way to go - If I destroy my 55 motor I'll give your idea some serious consideration before I spring for the spendy, aftermarket under-dash setup.

Thanks for the advice.

Charlie

only one disadvantage these are mostly onespeed motors, the twospeeds are bigger, but they work just fine.

regards and good luck Bas
and they don't really fit in, but we craft the housing over the new motor (hope this makes more sense.) <img src="confused.gif" border="0">

bdv, The Netherlands - Wow! I bet hotrodders down home where you live are down right genius when it comes to improvising and "Making Do" with what's available. I'd love to see a PIC of one of those farm equipment wiper motor retrofits.. I think it would be rather cool to see Massey Ferguson or Allis Chalmers tattoo'd all over everything under the hood instead of Moroso or Edelbrock.

No.. Really man, I admire a guy who can make anything work. This is how most custom streetrod parts were eventually developed - out of desire and necessity.

Thank for posting.

i will get a picture up shortly, i have made the same thing for my own 1955 coupe, as for the rest thanks for the compliment,
we don't have too much choise, if we want to build a bolt on rod from a catalog we would all have to be millionairs over here, so a little tinkering gets you a long way.

i will get some other pictures too on odd applications wich are rather common here due to a lack off parts.

while doing so i once build a nissan laural steering rack on a 1956 F100 truck, drove it out of my shop turned left , the car turned right, put the whole damn thing on the wrong side of the frontaxle. which was really a shame since it was practicly a bolt on.

but any way thanks and goodluck.

regards Bas
