....and the link to some dismantling & refurbishing instructions

Hello, thank you for these instructions!!! Chris from Germany

[Wittsend]

Thanks....if it helps but one owner get their wipers going

I see atin of rocket wd 40, this will be an instant sure for a wiper motor refurb, but not a pemanent one as wd 40 is silicone,as it dries it removes all the lubrication with it...a lighter oil...i.e 3in1 a vastly superior lubricant, allthough wd 40 is excellent as a parts washer for smaller items

[Dinty]

G'day All, as mentioned re a can of WD40, it was used to ease the studs out of the housing thats about all it's good for. This type of windscreen wiper generally comes your way either siezed solid from lack of lubrication or it has been vandalized and parts souvenired usually the collet screw and parking handle, this effectivley *&%^$ the wiper (here in Australia) because the mud wasps will get in an build nests out of mud and they fill the nests with spiders that have been paralised and the young wasps eat them alive. That particular motor was dismantled and cleaned some small parts were cannibilised from other donor wiper motors, lightly oiled and greased and it is now doing sterling service when ever we get caught out in the rain (which is not very often) anyway cheers Dennis :sheepskip
PS lots of BA size threads in the wipers :teacher

Thanks for that! Just stumbling around the site and came across this. I have one wiper that works, (slowly), and the passenger one that is dead. Only had my Series 2A for a couple of weeks so still finding stuff out. Could be a project for the coming weekend. Do both wipers need to work for the MoT, (coming up in Feb.)?

[Wittsend]

Do both wipers need to work for the MoT

If both are fitted - Yes!

If the screen is folded down/removed, no wipers or washers to be tested. (What you do when it rains is another matter)

Only the driver's screen needs a working wiper and washer.
You can not just remove the passenger wiper arm.
You have to remove the motor and blank the hole. Although some have claimed that pedantic testers don't like that even .... bit of a grey area. Would all screens have both holes, even if only the one wiper option was ordered 

Ultimately it's best to have both working...the folded screen option is really for emergency testing only - your wiper goes AWOL on the eve of the test.
Remember, if you fold the screen to display your tax disc. Not good enough to leave it on the screen. Also, Jim here, has problems lifting the bonnet. So check with your tester that everything is OK before you start.

Given our easy to follow instructions here, it should be possible to get the motor working. 2nd hand motors are on Ebay all the time and shouldn't cost the earth....

how do you get the spindle out? i can see a pin at the motor end, if i have to knock this out, i?m having problems with getting it out, do i have to give it a good whack with the #1 ? or is there any easier way (kidding myself again  :chuckle )

[ragnar]

   hello! I did it with mine..eeeh, the one old wipermotor I have, and it works. Had to isolate the wire inside and move the parts, with w?rth rust off.
Thanks for a great forum, wish you all happy new year!!!! :party

[elsielandy]

Dopey !!!!, At the arm end of the spindle under the ali section that fits against the windscreen frame there is a circlip !!!!

[gareth]

hi new to site find this very informative as my wipers are not the best but did pass the m.o.t

[richardhill]

as a landrover mechanic now servicing hummers in Ansbach if u need any hands on assistance come to Bayern and borrow my big hammer8or email me richardhil@libero.it)

I don't know if this helps but I did the wiper motor job this weekend and took a bunch of pics.  I posted it here:

Thanks for looking.

[Dopey]

when i took mine apart, i cleaned it all with a can of brake fluid brake cleaner fluid, and used the small straw that fixes on to the nozzle (the pressure forces the muck out and de greases it) i put it all back together now and its running nice and fast now 3 times faster than before, and i used that white lithium grease in an aerosol , which it meant to be better in winter as it doesn?t thicken up

[fidrover]

Do you mean brake fluid, or brake cleaner fluid?

[Dopey]

 ;) cleaner fluid

Greetings:
Are the rubber seals still available for these motors?
Thanks,
Chuck

On your side of the pond as well!!

[smokey 11a]

WD 40 is not Silicone, nor does it contain Silicone, read the distructions on the can.

[kernowcam]

so is the cork seal the same as the remade rubber one?

i wonder how hard it would be to make a press to cut cork gaskets. I have seen in the past plywood plates with vertical knives cut into slots to make the gasket. If i can get the info i would be up for setting up for this sort of thing. any ideas?

[eviljames]

I took some photos as I did my motor, might be useful to others.......

Thanks, it all adds to the knowledge base 

How the wiper switch is wired up


 

[jason bourne]

Would it be possible to up load a pick down and out back up  of a wiper motor linkage . Its in the haynes manual but . some tips in  setting back up the fleible cable .to the wheel boxese would e nice.
i have a problem it that my flexible casing has rusted out bad.most of the parts in the middlde between the 2 wheel boxes are gone. so using and angle grinder i cut way the .  damaged parts . the side to the motor(left side passenger) is workign when i switch on  but when i connect to the  dirvers side wheel box it jamms.
any suggestions to how the second wiper wheel box should be connected.

None of these articles or posts ever mention the field coil.
I am in the process of repairing two motors. One ran, but very slowly. I discovered that one of the field coil wires was missing, apparently broken off inside the windings. I was amazed that it ran at all, but presumably it can run weakly just on the residual magnetism in the iron?

I confirmed this on the other motor. I got it running well after a strip-down, but then after putting the cover on it ran slowly. I discovered I had accidentally unsoldered one of the field coil wires.

Has anyone ever successfully rewound a field coil?

Anyone any tips on overhauling the switch? How do you get a good earth connection when the pivot has worn?
How do you limit the end-stop - mine runs off the track and switches off again when fully turned.

[Clifford Pope]

I have just answered my own first question - yes, it is possible to rewind a field coil without any special equipment.

You need ideally a large free space without any obstacles to snag on the wire. Attach the free end to something at one end, eg a table etc, then walk into the space unwinding the coil. Try and turn the coil former as you go so as not to induce twists in the wire. Let the wire lie in large loose bundles, and go on until you reach the centre of the coil. Wind a good few inches round the plastic lug, and then very carefully rewind, taking care not to let any turns ride up over the plastc guides.

Obviously it is impossible to get a nice neat job if you don't have a proper winder, and I found I could only get about 80% of the wire back on again.
I wondered whether it would still work, and it does. The motor has plenty of power, and draws the same 2.3 amps running as does the other motor with the original coil.

[Calum]

I know from looking into winding my own electric guitar pickups and stuff that it can be done at home quite easily, usually using an electric drill with the bobbin or whatever on the drill, and spun round to 'wind in' the wire. Many people who make their own pickups at home use this method.

[Clifford Pope]

I thought about trying to concoct something like that, but couldn't think of a way of clamping the rather awkwardly shaped metal on the right axis.

[jason bourne]

Okay so i had a problem with the Flexiline cable. (single motor wiper) the caseing of fleicable was rusty and broken in several places. When the wipers were connected only one would work by its self .and then both were connected the motor . gags and cut out...

The problem was thaat the rust and the outer caseing were not helping the fiel coil . i think you call it to move.

the solution i used was to use a hacksaw to remove  the  outer casing..
i was able to get a small aluminuim pipe size that match back to the outer casing .(local hard ware)
then i just measured the length bewteen the wheel boxes
cut the lengths and then tapered the ends to look back like the caseing i cut off
then i just slide the flexirivee cable through the pipe and then tighten the wheel box clamps.
i didint have to replace the line bewteen the 1 fisrt wheel box andthe motor so i didint trouble it  but i assuyme you just have to take your time and bend it to fit back and then tapper on side first and push it intothe
