Hi, I've got an 07 Sportsman 500 HO. I was working on some clutch problems and so I had the belt box housing off. I was riding around with it like that for a few hundred yards and this breather, which is normally held by a bracket that is held on with one of those belt box housing screws was flopping around, got caught in the primary clutch, and shattered. I put what's left of it back in the bracket but it makes a bad hissing sound now when I ride. WHAT IS THIS THING CALLED? The hose for it runs down to where the coolant lines are, but I cannot find a name for it to order a replacement. Any help would be appreciated.

 

Crank case vent(items 12-16) goes to the right hand side of the air box. Left side is the vent from the oil tank.
