Truly Awesome
...and not the way you'd think. It seems to still work, except the moment you hook air up to it, it fires up like you've got the trigger pulled full time. Trigger moves, and I've knocked out the roll pin to expose the rod ("valve stem") behind the trigger, and pressing under it with a punch does seem to make some movement on the mechanism inside the tool. I've oiled, re-oiled, messed with it for too long and it hasn't changed.
This is the Husky "Pro" 550 (model HSTC4140) I bought for the shop around 12 years ago and it's truly not been used enough that I'd expect problems out of it.
I don't see anything in the parts diagram behind the valve stem (#34) so I'm confused as to what is moving back there when I press on it. There's a tiny O ring (#33) that sits in the middle of the valve stem, and while I guess it could be worn and cause problems, there's no way this one tiny O ring is meant to hold back all the pressure? Is it? I've never repaired an air impact before.
