I've seen LAPPED Oil Pump Gear Sets for sale.
May I ask what is lapped on them and can one do it themself ?
I can see how the bottom face of the Gears that rides on the aluminum cover plate could be lapped so they are really nice and smooth when they are against the aluminum cover plate, but is there some other area that is also lapped ? like the faces of the gears where the mesh with one another ? or the outer tips of the gears which always seem to be awfully rough in my opinion, even though they don't actually touch the housing walls. Or is it maybe that one takes and old housing and spins the gears in it with a drill or something while lapping compound is on the gears to lap the gearts to one another ??? Just curious. Thanks (:->)
