Abstract
A tool that enables resurfacing of exhaust port flanges in the substantial absence of engine disassembly. An air motor that controls rotation of a resurfacing device is carried at the end of an arm assembly including an elbow like joint so that the motor is positionable over a wide range of positions. The proximal end of the arm assembly is mounted on a shaft and an adjustment knob enables the position of the arm assembly and hence the motor to be axially adjusted to facilitate positioning of the motor with respect to the port to be resurfaced. The shaft has a first part with a flat bottom that overlies a base plate that is secured to a cylinder head and spaced from the head by elongate spacers. Fine adjustment of the motor's position is achieved by rocking a preselected end of the shaft away from the base plate and by tilting the shaft laterally with respect to the base plate.
