احصل على السعرValve grinding is administered with 3 separate grinding angles leaving the surfaces somewhat striated from the grinding action. The action to smooth out these striations is called valve lapping. This is where the valve is smeared with a little valve lapping compound placed in the valve pocket where the valve the valve seat meet.
احصل على السعرSpread a bit of grinding compound onto the edge of the valve. Stick the Rubber Cup On the Valve Face Once the valve is in the head, the next step is to wet the suction cup on the lapper and stick it on the valve face. Once the lapper is grabbing the valve, you begin the lapping process.
احصل على السعرLapping is only useful for fine finish work after the seats have been refinished and the valves finished or replaced with new ones. By lapping worn valves against a worn valve seat, all you are doing is transferring the worn condition of one part to the other. If you continue to have leaking valves, the head needs machine shop work.
