To install a BONEHAM serrated press-fit bushing, press it into a drilled or reamed hole in the jig plate using an arbor press or hydraulic press. The serrations on the outer diameter bite into the plate material, securing the bushing against rotation. Ensure the hole diameter matches the bushing's outside diameter tolerance.
