<p>A tool for resurfacing a counterbore of a cylinder bore in an engine block includes a holder fixedly attached to the engine block using existing threaded holes, and a cutter rotatably supported by the holder and axially movable while being rotated. The cutter is positioned to cut and resurface a counterbore in the top of the cylinder bore. A plurality of springs bias the cutter head axially toward the engine block while rotating the cutter, thus providing a uniform force while cutting and resurfacing the counterbore. A ratchet wrench matably engages the upper end of the shaft to rotate the cutter, with the ratchet wrench extending in a single lateral direction from the shaft. A related method is also discussed.</p> |
