That's not from a Hayden tensioner. I can't remember who but somebody makes a hydraulic dampened tensioner. That looks like a piece of a valve for one of them.

You're thinking of the Southern Oregon Hotbikes HB125 Hydraulic Automatic Primary Chain Tensioner.
Here are a couple more pics. The top one is how the apparatus was sitting in primary. With the springs still in the hole in shoe. Sitting on bottom of primary with chain riding on shoe. Useless. No tension on chain whatsoever.
The second pic is how I guess the piece of aluminum went. As a shim between the springs and the bottom of primary. Maybe. It doesn't look like the ones pictured in the ads.
And. Yes. Before you ask. There is a bar that goes on the out board side of the shoe. That sandwiches the shoe in. I just left it out for clarity.
I consider myself getting off lucky. Just have to replace chain and adjuster.
Hayden, somebody probably removed a couple of the retaining ears to slip the tensioner shim in instead of dropping the side off and wrestling with it like you are supposed to. There's nothing to lock the adjuster shoe in place just the springs tensioning it. So what happens is the primary chain is bouncing around with a lot more slack than you think under load, so the goobered up shim spits itself out when the springs get to vibrating & bouncing around and gets chewed up rattling around inside primary like you see in the first picture. All that crap on the clutch spring & pressure plate is the ground up fine particles in the oil getting slung out in the gap between the two when assembled like a centrifuge.
I've been dicking with Haydens since they first came out, seen many a shovel with them and they never stayed in very long they just don't work It's a lazy man's gimmick for those who think they can get away from proper chain maintenance. It will not hold the primary chain at the proper tension, it's always going to be tight standing then run loose once you get some RPM's up and the springs compress. I've seen them allow the chain to hit the upper part of the inner primary.
That's the latest design, operates like the stock later harley units do. That looks better than the old style but till I have hands on with one I'll reserve judgement on whether it actually works this time.

As per my photo above in post #20, there are a lot of parts missing in these pics, including the mounting bolt and a large piece of thick steel! If you didn't find them when taking off the primary cover the darned thing wasn't installed correctly, so its no surprise it 'failed'. Looks like operator error with a PO.
