So USPS turned a linear solenoid into a non-linear solenoid?
Well.... There's a interesting thought on that. I don't think they actually "damaged" it. Deformed maybe, but not damaged. Here's why.
The Seller is sending an exact replacement without issue (there are great sellers on eBay!!), So I figured I'd take a look and see just what the fuss is all about.
There are several tutorials on disassembly of these, so I grabbed a pair of my flush side cutters from my electronic kit and slowly peeled back the roll on the non-valve end. It unrolled easily and in a few minutes I had it apart.
I was surprised by what I found. The actual shuttle for the solenoid doesn't extend into the valve further than maybe 3/16th. There's a separate piston that does the work and the two meet at a rounded point. So where it was bent was actually between the joint and it was still capable of moving... Maybe not at 300hz it normally does, but it was still rattling back and forth. The actual work part of the solenoid was unharmed. So I straightened out all out. Gently rerolled the valve end of it and checked for accuracy. Perfectly straight. Proceed to clean it as many of the tutorials show and then rolled the far end back over. A gentle shake let's you know the actuator is free and moving that little bit.
Now.... I'm not using it since I have another coming, but if it was a ride or walk consideration, I'd have no issue reinstalling it and powering it up. They really are quite simple and I see exactly why they load up with particulates and fail. The only issue is their static adjustment and I have found several videos showing how to clone your original settings and another showing what the OEM (valve mfg) setting is which is where most all of them are set unless there's an issue from the build floor.
So although I was a little down about the delay, I was able to explore a little and gain a little more insight to these slush boxes and hopefully that will pay off in the future as I am looking to build a mid-engine street car and I am planning on a Volvo power plant as I can take the entire sub frame and bolt it into my frame.
