iaink 346 Posted March 8, 2022 Share Posted March 8, 2022 Any one had issues with rust on the abs ring on their NC ? Looks like it is just galvanised. Can it be painted with zinc galvanised paint and would the abs still work ok ? Maybe it is time to change my bike 😀 Thanks Link to post

I reomived it, wire brushed it up and repainted with satin black paint. I don't think it's galvanised, just silver paint. I thought it looked better in black. It didn't rust again. I suspect just too little paint applied initially. Link to post
alhendo1 3,045 Posted March 8, 2022 Share Posted March 8, 2022 Yes..my 500x has it...I've just left it but might give it a wire brush at some point....see if I can shift it. Link to post

Sorry I used a light coat of silver, a light coat should not alter the air gap enough to alter the magnetic field, I stand corrected when @Andy m comes along! 😂 1 Link to post

Johnnie Mototrans 2,766 Posted March 8, 2022 Share Posted March 8, 2022 What's the sensor? If its a magnet then you would need to use some very metallic paint to confuse it. If optical then you would need some very very very thick paint to confuse it. Surely this is getting overthunk. Link to post
outrunner 4,457 Posted March 8, 2022 Share Posted March 8, 2022 I cleaned mine once and gave it a coat of clear laquer but it did not take too long to corrode again so I have just left it rusty, there is probably more rust on it now than there was paint when it was new. Â Andy. Link to post

If its a magnet then you would need to use some very metallic paint to confuse it. If optical then you would need some very very very thick paint to confuse it. Surely this is getting overthunk. ABS sensors are inductive. Just a coil that makes a low (0.3 - 1.5 V) AC signal.  The pole wheels need to be conductive and have clear gaps. Any sort of insulation over the teeth or conductive material in the gaps reduces the clarity of the signal. The specs call for clear squared off edges and minimal (0.1 mm) run out.  I wouldn't mess, if there is enough (non conductive) rust to give a bad signal they need replacing. ACF-50 the new ones. If you must use a brush, use a nylon or brass one, bits of random iron wire shrapnel embedded into the polewheel aren't great. Coatings need to be thin. If it is just cosmetic discolouration leave it alone, either go for a ride or take your OCD out on your bathroom.  Andy   1 2 2 Link to post
jeremyr62 2,554 Posted March 9, 2022 Share Posted March 9, 2022 (edited) Use a chelating rust remover if you must. Don't use an aggressive one with acid. Metal Rescue, Evapo-rust, Restore are some examples. In my experience these are fantastic at just taking off the rust and leaving the uncorroded steel alone. Or if you want to go cheap, Lyons black treacle (mechanism is the same)Â diluted with water also works but takes a lot longer. Edited March 9, 2022 by jeremyr62 1 Link to post
djsb 491 Posted April 18, 2022 Share Posted April 18, 2022 Would silver conductive paint (you can buy a pen type applicator for circuit repair) work ok after derusting with Evaporust? Link to post

Can you apply it evenly? Can you key the surface and do whatever prep is needed to make paint stay stuck?  If you fill the gaps between teeth you won't get a signal. If instead hi-lo-hi.... the waveform is more hiiiiiiiiiiii-lo-hiiiiiiiiiii..., because the coating is uneven or flaking off, it'll ping the light (and the dozier sort of tech will read the code description and then change the wheel bearings).  As someone who has never bought a new pole wheel, I have to say don't do it. Having seen the aftermarket mark up and can appreciate why you'd try. If the light goes off and stays off after reassembly it's job done, if not, get the paint stripper out.  Andy Edited April 18, 2022 by Andy m Link to post

Trev 18,625 Posted April 18, 2022 Share Posted April 18, 2022 Ah the old rusty ring problem, can't believe I missed this when was first posted 😳 4 Link to post
rjp996 1,091 Posted April 25, 2022 Share Posted April 25, 2022 rubbed mine down a bit and black spray painted last time I had the wheel off - looked better for another year and worked fine :-), now the rest of the bike looks like an 80k+ mile commuter bike that's used hard and put away wet ;-) - but its been a great bike 2 Link to post

You are adding a layer of magnetic insulation and narrowing)/rounding the gaps between teeth. If the coating is thin enough it will work but it will be less tolerant of airgap variation.  Andy Link to post

SteveThackery 3,090 Posted July 16, 2022 Share Posted July 16, 2022 I've been doing some research into this subject. There is no such thing as a material which will block or resist magnetic fields.  All materials have a quality known as magnetic permeability. A vacuum, and air, have a relative permeability of 1. Magnetic materials like iron have a permeability greater than 1. This means they "carry" a magnetic field more easily than a vacuum can.  There is no material I can find that has a permeability significantly less than 1 (ie which resists a magnetic field more than air or a vacuum). All the plastics I looked at have a permeability of 1. In other words, they look exactly like air to a magnetic field.  So, there would seem to be no reason why you can't paint or plastic-coat the ABS ring, provided the coating is thin enough to clear the sensor. I wonder if that is the main reason they aren't coated from new: the gap between the sensor and the metal ABS ring must be small, and plastic coatings take up a good part of that gap. Therefore they are protected from corrosion by electroplating instead (which is extremely thin compared with paint or plastic).  That's what my research says. Always happy to be proved wrong, of course! That's how we learn stuff. Link to post
Andy m 23,527 Posted July 16, 2022 Share Posted July 16, 2022 What's the airgap filled with? What's the airgap the equivalent of when there is plastic then air above the steel?  If you can get the sensor tip to run with zero clearance or the plastic is as accommodating as air for getting out of the way when a bearing wobbles you are sorted.  You have 0.3 mm to play with.  Andy 2 Link to post
