My Bulldog was hammering poorly so I replaced the "O" ring. It is still hammering poorly. Do I need to replace the Hammer Piston?

Check the piston, and sleeve. Does it have any serious wear marks? If so, replace. I would put a whole service pack in it......all o-rings and grease. Not just the stiker o-ring.
