I believe scot just sent you a link so you could look the part up.Its the hydrolic shaft that pushes the clutch plate out to dissengage the clutch.Little hole where the clutch housing bolts on.There should be 2 rods.Pute the first rod in and the ball bearing then the second rod which also is canected to the clutch presure plate.
