ABSTRACT:
A valve seat forming tool includes a pilot rod that may be inserted into the valve rod opening of an engine block. A cutter assembly including a pair of cutter blades projecting radially outwardly from the assembly is rotatably positioned on the rod and may be rotated to cause the cutter blades to engage and resurface a valve seat. The tool may be placed in a calibration block to calibrate blade position. Subsequent to calibration, the assembly is positioned over a valve seat of an engine block. The cutter blades are then radially adjustable by means of a micrometer and subsequent to adjustment the cutter blades are rotated manually to cause the blades to reform the surface of the valve seat.
