How To - Converting Your 6V Wiper Motor Into A 12V Motor

Post by OxonPhil » Mon Feb 01, 2010 1:17 pm

Last year I bought a voltage drop resistor for the wiper motor, as this seemed to be the only way to convert your 6V motor into a 12V motor.......but not now :cheers:

I found the 12V armature on the Wolfsburg West website, and thought was the better way to go (more reliable over time).

It always seems to be really difficult to get to the wiper motor (due to the location), so a fix that will last a long time appealed to me.

This is a 'How-To' modify your wiper motor from 6V to 12V.

Note: The motor must be a SWF type motor.

I decided to buy the wiper motor armature directly from Wolfsburg West, as I was just in the USA (and this was the cheapest option), but these can be bought from Justin at Custom & Commercial here in the UK.

Image

Remove the spring and Split the contacts.

Image

Remove the contacts plate.

Image

Remove the old 6V armature.

Image

Old and new armatures.

Image

Image

I made sure that the shaft was greased (oh er..... 8O )

Inserted the new 12V armature.

Image

I rotated it until it fell into place.

Image

Refit the contacts plate.

Image

Reconnected the spring (that holds the contacts in place).

Image

And tested it to make sure it works OK.

I can't tell you how easy this upgrade was :D

This has to be the way to convert your wiper motor (and should make it last another 50 years).


:D :D

Oxonphil - you da man !

That certainly is a handy know how.

one question how will i know if mine is a SWF motor, I am to assume that it is the name of the manufacturer and will be clear to see on the motor ?

I don't like to assume- it makes an ass out of you and me.

A bit like assuming you don't need to convert your 6v van to 12v just because you IRS the back !

Will be interested to see the wipers in operation. ie to see the sweep rate compared to a stock wiper motor.

Oxon Phil

thanks for the photo, most helpfull. sadly this route might not work for me unless you can tell me otherwise-but you did mention this method was for SWF only.

my 6v is a vw one. a Black cylinder part number painted in white 2119551110 the part at the bottom of the black casing, where the terminals are- the ali mould, has in small letter swf.

what do you think ?

The truth is that I don't know......

But........my wiper motor is also a VW motor (SWF were the manufacturers I'm guessing).

Mine has the same part number written on the side as yours:

I think the best thing to do would be to open it up and have a look....

Hope this helps ??

Phil. :D

I have just fitted my 12v armature as described above, thought I should test it prior to refit, it was working fine as a 6v with a headlight bulb wired in line as described on here by peter Good. I connected the two spade connectors to the battery and nothing happened?? There is a spark at the brushes if i pull them away from the armature slightly, so feed deffo getting through...have i got a duff motor? Or should the casing be earthed on the chassis or what????

Hope someone can help?
Cheers, Goose

SWF is (or was) the OEM German manufacturer of mainly motors, switches and the like, and now part of the French Valeo group. The armature will only fit the type shown in the pictures, none other. Its a good clean way of doing a conversion. The supply of the armature can be a bit patchy. Wanted one for a customer about 18 months ago, just couldn't get one from anywhere.
Goose, you need to earth return the motor.

Thanks fore the tip Peter, turns out i was wiring it backwards, so the earth was the problem! :roll: Switched over the wires and it runs like a dream, much quieter too- though renewing all the grease probably helped!

For others that want to do this please remember that SWF made many different 'loaf' wiper motors - I have a collection of them (sad or what?). The WW armatures ONLY fit SWF motors from 1958-1966 Beetles and 1955-1964 Buses. They will not fit 64 - 66 6V motors because these have a different arrangement on the end that goes into the gearbox. They will not fit any Bosch made motor either.

You can modify early beetle and bus motors to fit later buses (with the flat linkages and full frames) by welding the longer and thinner linkage spindle from a late bus onto the early motor arm. I've done this several times, but it's easier to get a beetle 12v motor and fit the bus spindle on to the arm. Then you don't need a WW armature.

This is my bid for wiper motor anorak 2010, although I think Peter G will probably win on points. I'll get my coat.............................................

Brian,
As I said many times before we all know you have anoraks of many colours!


err....so I also have lots of wipers trying to solve the 12v route for eldest son...who had a Bay unit fitted by the PO to solve the problem..
My 12v armature came off thesamba.com from a private seller who found it did not fit the two speed 6v set up..
Works great!
