I was asked by a friend to help him with his 10 year old Scag truck loader. I do not have the model number as the tag is missing. He blew the Vanguard engine and bought a new one. I took it apart and now reassembling. My question is does anyone know the correct bolt torque for the tapered hub (#484819) to the impeller. The threaded holes (to press the impeller off) in the hub were already a bit beat up before I got to it (I tapped them out) so I dont want to overtighten the impeller and have it not come off next time. It was originally a 29hp and it has an impeller that is about 12inches in diameter. Thanks
