Default Re: How do you install a new piston?

Make sure you line up the anti rotation pin in the ring groove with the end gap of the ring.
Use some motor oil on the ring/piston when you replace it into the cylinder.
Use an extra set of hands to let the cylinder down onto the piston while you hold the ring in place unless you have a ring squeezer.
