I feel like a fucking idiot but…
I have stripped 3 fucking Thunder kingpins back to back and I genuinely don’t think they should have stripped out. Is this all caused because I use the included washer from my bones bushings or what is going on? As Mugatu once said, I feel like I’m taking crazy pills.
Hollow kingpins?
Seen a lot more hollow kingpins have issues, but I know any kingpin can strip for various reasons.
One of the guys I skate with went through a tighter truck phase and he would try to tighten the bones bushings down that would then rebound in such a way that would push the kingpin nut off the kingpin from the forces of doing tricks.
And no it shouldn't be happening, but some things like that example above do have adverse affects on product, that would not usually happen in other situations.
Hollow kingpins yes. I skate the hard bushings but I had them basically flush. Took em apart to throw a bones medium and a bones hard together and then it wouldn’t go back on
Maybe you cross threaded on accident last time you put your kp nut on?
could easily see that happening if your kp had been ground down a bit already, damaging the top threads.
The two things that helped a bit (but not entirely enough to salvage the kingpins after a few of these same occurrences) were to get a decent rethreader for kingpins, more so than just the Ace tool, as that was a bit soft in the metal on hollow kingpins, and a wire brush, to brush out the bits of the nuts that were left in the threads that prevented the new nut or even sometimes the rethreader from getting a lock and doing what they were supposed to do.
After half a dozen kingpin nuts popping off, especially the last one or two, it was give up time on the kingpin and switch out the baseplates entirely, as the first set he tried to remove the kingpins just ended in misery.
Bones hard bushings are good at putting so much pressure on the kingpin nut, whatever the quality of metal it may or may not be, so that it would push it off even half a thread, which then left metal on the kingpin itself and blunted the future efforts to remove and replace the nuts.
That is what we worked out, but still not 100% sure about the whole thing, but he ended up going with other bushings and then not having them half as tight so bones hard bushings work again, but doing the trucks up as tight as he had them meant they were popping the nuts off with enough force and time.
Sorry probably repeating a bit there, but just getting it all out.
Still a bit of a mystery, but at least it is not happening, or not happening as much as he regularly changes out kingpin nuts now as well.
