Valve Seat Face Cutter

The current price for this tool (part # 06-3969) is $0.00, as of 12/14/17.


If, when the valves are removed, the Valve seats are found to be excessively burnt or pitted, they must be recut to restore a smooth, even face before new valves are ground in. The most important part of cutting new faces is to remove as little metal as possible while removing all traces of burnt material. Pass the cutter into the valve seat with the pilot into the valve guide. Using firm, even pressure to avoid chatter, take the first cut for about 90° to 120°. Repeat until the faces are free of any pitting. Thoroughly clean the combustion chamber and port areas. Repeat for other burnt seats and grind in valves normally.
