Slow Wiper Motor Refurb

[M@tt 77]

I thought as i had a few spare wiper motors i'd give it a go of refurbing them to get one to replace my current ailing motor which struggles to work when travelling at speed.

 

So heres a quick stp by step of what i did

 

1. Remove the black cylindrical motor windings case cover by undoing the 2x7mm bolts, which will leave you with this

 

2. Clean out the case and windings of any dust or dirt (compressed air is ideal)

 

3. Clean up the rotating spindle/bush surfaces with some fine wet/dry emery paper so that you are left with a shiney/smooth copper finish

 

4. refit the windings case and 2 bolts. you might want to put a bit of selant round the mating surfaces to pretect from any poterntial rain water ingress.

 

5. remove the cover of the gear housing by undoing the 4x7mm bolts

 

6. On the revers of the cover you will find a 3 pronged contact this may be covered in gunk. clean this up and lightly sand the end of the prongs so that you have clean fresh metal.

 

7. Then turn your attention to the contact surface on the top of the large gear wheel. Clean up any grease/dirt on the surface and lightly sand again with some wet/dry papr to bring up a fresh contact surface.

 

8. Its then just a case of reattaching the lid and 4 bolts, again using a bit of gasket sealant to stop and water getting in.

 

9. Finally i gave the plug connector terminals a bit of a cleanup with some wet and dry as well.

 

Only took about 10 mins or so and hopefully should give a lot fresher feeling motor, i'll post back once ive fitted the new motor.(tomorrow hopefully)

so how did it turn out?

 

Are you still marvelling at your speedy wipers?

[M@tt 77]

didn't get chance to fit them i'll have a bash today when i get home

That looks really good Matt I think I'll give that a go on my recently acquired 106 motor, before sticking it in my 205.

What kind of grease is in the gearbox? Is it standard LM or something else?

its looks like chunks of wax tbh so i'm not sure exactly what it is

but i reckon any grease would do

 

I'm hazarding a guess that the most likely bit to cause the motors poor performance is the layer of old powder over the contact surface between the bushes and the motor windings.

update

 

the refurb worked a treat

 

The motors wipe perfectly even when the screen is dry which is when it usually struggled. Haven't taken it for a spin yet to see what its like when travelling at speed but should be ok i think

 

this is what the motor i removed from the car looked like, the contact surfaces were really heavily covered

 

anyone who experiences this should give it aa whirl, well worth 20mins of your time

Excellent write up - it should be an article on the main site.

 

off to break my wipers!

Superb guide.....another thing to add to my list of "To Do" jobs.

I striped my 'new' 106 wiper motor earlier this evening. Was in slightly better condition than yours inside. The 'parking' contacts on top of the gear wheel were in great condition, but the commutator in the motor was in a similar state to yours Matt.

So I cleaned it all up, thanks to your guide Mine had a rubber gasket where the cover bolted on the gearbox casing, was this the case with yours?

 

Just need to install it this weekend, although we have a lot of rain predicted.

yes mine had a rubber gasket on that cover as well, however bits of it had perished around the bolt holes so i used a bit of sealant just to be safe

Good man will give mine a clean and refurb on sunday.

[steve@cornwall 100]

Agreed, ace write-up. I will also be doing this now

Somthing else that helps is oiling the 2 spindles that the wipers bolt to, made a bit of a difference to mine, im going to do this when i get a chance though as there still not brilliant,

 

Good write up, shoud deff be and article or a sticky

Dear M@tt,

 

My wiper blades jump very badly and I thought it was becausethe wire and relay are too old so changed them all a few years ago but no help. I followed your guide and refurbished mine last Saturday. The wiper blades no longer jumping even when the screen is DRY! And it is running very smooth too. I have to thank you for putting a guide up that I have never think of refurbishing the motor and all gears.

 

Thanks again!

[M@tt 77]

thats excellent glad it was of some use,

 

see how we are so pleased at sorting the little things out on these cars that we take for granted on all modern ones ie working wipers, non squeaking heater fan motors, non rattling sunvisor holders

One thing that is worth doing is putting some RainX on the screen too as it makes the wipers run smoother. Also clean your wiper blades with vinegar then RainX (if you are too tight to buy some one ones!)

 

Nice one Matt. At least there was plenty of rain to try it out! The write up is is something very similar the what I have done for my Alfa in the past here.

Beast of a guide, nice one. Tried this tonight as I wanna get my car perfect before it hits the road (may be some time), and this is one of many niggles my car has I actually refurbed them before I read this guide which i stumbled across about 10 mins ago :S mine was rusted to buggery!

I did everything apart from lightly sand those 3 prongs down which connects the the big gear wheel.

My wipers are much faster, but when I go to turn them off on stalk, they stop in the centre of the screen diagonally. And the arms are connected up properly could this be a bad connection with the 3 prongs??

defiantely agree with oiling/ cleaning/ refurbing the wiper spindles. Mine were almost seized solid they were that bad. There's a circlip at the bottom. Remove it and then pull the shaft out of the plastic housing. Mine was that tight I had to use a mallet and drift! Rubber the red rusty spindles down and plenty of grease later the the difference is amazing!

I think some of these motors are to far gone.

I tried the refurb on my car and it made them worse to the point that i got an advisory for the MOT!

 

However, i fitted the motor from a late model saxo and the wipers are now as good as you could hope from any car! only cost me £10 and the new motor is plug and play.

Mine is a very strange case. Refurbed mine and it did work very well, but only for the first 10 minutes when I switched it on everytime. After about 30 minutes it is only a little better than before. I guess it is because of the age of the motor is TOO OLD.

 

Found a wiper motor from a 306S16 and it looks almost identical even the gear set. Will try to put it on later when I have time and will report the result here.
