The galling in the piston bore is very common. Fortunately it doesn't much
matter as the pump makes sufficient pressure to operate the unit despite
small amounts of leakage. The hard part is getting the piston back in the
bore with out braking the VERY delicate rings. Make sure the splits are all
at 90 degrees to the adjacent rings, just like a piston in your block. The
bore is aluminum so do not try to hone. Clean the small inlet holes around
the circumference of the housing. Wet the new O-rings with grease or oil
prior to re-insertion.
