The flywheel with copper sleeve is one of the main parts of J23 mechanical rigid clutch drive punch. After removing the flywheel, lay the flywheel flat and make it high and flat.

        Remove the mounting screw of the copper sleeve on both sides, insert the cushion sleeve into the middle sleeve with a cushion sleeve smaller than the inner hole of the middle sleeve on one side, hit the cushion sleeve, and remove the copper sleeve and the copper sleeve on one side together.

        Then the flywheel surface, with the flywheel hole slightly smaller than the sleeve or take turns from 90 degrees from the direction of four points on the other side of the copper sleeve inner edge, to remove it.

        During installation, press the middle sleeve into the inner hole to ensure equal distance on both sides, then press the copper sleeve into the hole from both sides respectively, and finally drill the tapping seam screw hole again and tighten the screw.
