The ATC 12‑102‑02 Engine Barring Socket is a precision-machined tool designed for rotating and positioning heavy-duty diesel engines during service procedures. Purpose-built for MaxxForce 11/13, Navistar N13 and International A26 engine systems, this tool enables safe, controlled engine barring via the timing window opening.
Manufactured with durable steel and supplied with the necessary mounting bolts and washers, the 12-102-02 makes engine service more efficient—whether verifying timing marks, setting valve lash, performing piston replacement, or preparing for component removal. The tool’s simple slip-fit design couples to the flywheel via the timing window, allowing a standard ½″ drive ratchet or breaker bar to rotate the crank with confidence.
