I am trying to assembly my blower/vac, Husqvarna Model 125BV, X Series. The Tube Clamp Bolt (part #17) appears to be too short. Another problem seems to be that one end of the hole where the Tube Clamp Bolt goes through is cut out for a hex shape. However, neither end of the Tube Clamp Bolt is hex-shaped. The manual contains no real directions, just a diagram. Can you advise? Is it possible that we were sent the wrong Tube Clamp Bolt? Thank you.
