Ion Solenoid armature?

[DocsMachine]

I've been going over my lists of projects, and came across one I've had on the table for... I think about two years now.

I'd been told the "armatures"- the center poppet portion- of the Ion solenoid eventually wears out. The seals go bad, and SO/GOG is of course no longer manufacturing replacements. I had an MCB'er send me a complete solenoid, and I have a functional-last-I-checked Ion, so I think I can dupe the part fairly easily.

I'm wondering, before I do, if anyone else had started making them, and/or is it even worth trying to re-make? I know SP used to brag they'd made something like a quarter million of them, but it's also been a while, and I can see a bunch being tossed or parted out (or mech'ed) if parts can't be easily had.

Anybody have the straight poop?

There is a gentleman by the name Keion Doss making new armatures.
Very well known/saturated in the Facebook smart parts community, but he is the only one, and only deals via Facebook.

Keion Doss is a great guy. I bought some armatures from him last year to fix a customers ION. The first batch I bought from him had some sealing problems. It turned out to be a material spec mistake, and he sent out some corrected ones quickly. You can buy from him off of Facebook if you email him directly at keiondoss at yahoo dot com.

I've seen them on FB, but I would buy some if you made them. I have a bag of old boards that are otherwise useless without new armatures.

IRT SP making millions of them, there is an individual on Ebay who I beleive ended up with SPs inventory when they closed down their Latrobe location. He's sold around 1K of new old stock for the last few years. Understanding that the failure of these is due to the sealong material breaking down over time, I bought a pair and they were in decent shape but, I know they could go at any point.

I would avoid those. I bought ten from him in 2023, hoping at least a few would be good. They weren't, as they were all suffering from age problems. He tried to blame it on the lubrication I used, even though I never even installed most of them. I checked them for soft/sticky right out of the box. I only installed the "best" two of the ten, hoping that they might work. They didn't. I also gave him a lesson on lubes that I'm sure he TL;DR.

Keion Doss's new ones are the only way to go right now.

If those seals are urethane, age related decline is to be expected. Urethane o-rings have a typical shelf life of 5-10 years.

A couple years back, either an MCB'er or a Guilder pointed out there's two kinds of polyurethane- ester base and ether base.

Ester is cheaper, and undergoes hydrolysis- basically, it depolymerizes- much more readily than the more expensive ether base.

You can't tell by looking at them- you'd need to get a spec from the manufacturer, but I know I'm still using tank O-rings out of a big bag a field-owner gave me when he closed his indoor down in 2001. Those tank 'rings are as good today as they were when he gave me the bag.

The Ions were very much made to a down-to-the-penny price point, so you can guarantee that SP used the cheapest O-rings they could get their hands on.
