  • Pneumatic tappet adjustment tool
    Patent number: 7600452
    Abstract: A tool for adjusting the tappet clearance in the valve actuation system of an internal combustion engine includes a screw adjustment portion that is driven by a pneumatic powered screw driver. The pneumatic power to the screw driver is regulated to cause the screw driver to position the screw so that the desired biasing force is present. The screw driver bit passes through the head portion of a torque limiting wrench which is used to loosen and tighten the jam nut that secures the tappet adjustment screw. The tool also has a pneumatic driven gripping mechanism to hold the screw driver bit in position and prevent inadvertent displacement of the tappet adjustment screw while the jam nut is tightened.
