GS wipers, speed or lack thereof

[Stickyfinger]

and please spray the area with some rust preventive treatment/wax such as dinatrol...............sorry my OCD kicked in

[macplaxton]

It is indeed looking quite crap and neglected at the moment. It was never pristine, but was usually quite presentable. This car has a load of Dinitrol about it, it's just in the embarrassing state of needing a load more.

I shall go off and flog myself with a big stick for not doing it sooner.


I'll have a bash at bonding, but if I require another motor Malc, I'll only be after one.

Sorry it's just it looks so easy to get to. I am convinced it helps a lot in preventing micro condensation in large dead air area like that, which shows up as corrosion just like that does. Helps the alloy as well as it soaks into the oxide layer preventing oxygen transfer.

Update time! Bought some metal epoxy to stick the magnet back where it belongs. http://www.unibond.co.uk/en/diy-adhesiv ... metal.html" onclick="window.open(this.href);return false;

Cleaned the back of the magnet and keyed it up. Ditto the casing which was a bit surface rusty. Whilst the old adhesive was white, I couldn't see any around the other magnet, perhaps someone got there before me with a repair? Either way, I elected to plonk the magnet back where I found it, which was slightly off centre.

Still a bit lame, but they work without a racket now. I suspect the magnets could do with re-magnetizing. Being a closed-ended bucket I've no idea how you get a keeper ring in there.

Anyway, here's the vid. (c. 20 sec is speed 1, c. 30 sec is speed 2)



If you have a GS or GSA with quicker wipers, video it and show me what I'm missing!

Cheers.

Bit of a rubbish video - not familiar or practiced in same.

Wiper speeds not dissimilar to yours, but perhaps a little less 'strained':

That video is perfectly fine, we're not chasing BAFTAs!

I see yours has a a bit more oomph and it's on a dry screen too. I had a bit of drizzle to aid things along. I'll put up with it the now as it has always been like that for me, but I'll look into it again later.

Many thanks.

are the wheel box's (spindle housing's ) nice and free/smooth in there movement, maybe they are binding/tighter than they should be,
although i see in one of your picy's you have the cast alloy spindle housing's, they can still bind/cause drag even though they have a bronze bush through them,

otherwise maybe you dont have the same clearance between the armature and the re/glued magnet as the other, as i believe the clearance has to be equal

Rich,

I think the motor will have overheated because of the spindles seizing - this is a very common fault on the 2CV/Dyane/Ami and eventually will either cook the armature windings or damage the plastic insulators on the three contacts.

Hope you'll sort it by reattaching the stator magnet; might be worth a look at the other one to see if it ought to be re-glued.

Free as a bird. When disconnected from the motor the whole linkage is dead easy to move manually. No sign of seizing.

Well they work well enough (was raining today driving back from work), just being fussy really. My suspicions from the visible white epoxy on the loose weight was that it may have been messed with before. The other one doesn't have any visible glue peeking out and seems firmly attached. I maybe should of set the loose magnet dead opposite the non-loose one, but I elected on the day to just go by the lining up with white goo marks on the body and magnet and scribing a line and leaving it as I found it.

Having said that, the loose magnet does have some scuffing from the armature on the inside face, so there is a bit more clearance between the magnet and armature at that point in the cycle. The main thing is I can see where I'm going!

Mike, I hope you don't mind me asking, but did you read the second page of this thread?

[uhn113x]

Don't mind at all; 'twas yesterday though so I've probably forgotten by now! Read it again for good measure, though.

I wish I could remember what I did when I refurbed a few similar Ami wiper motors though, in respect of how the magnets were attached to the casing.

Good to hear the spindles are free as that's the bête noire in all these systems.

[citronut]

good the spindles are free, the metal bodied type do seem to be better than the nylon type, and i think easier to sort if need be
