High-torque operations on a Detroit Diesel DD5 demand a mechanical lock you can trust. The ATCW936589014000 provides the secure engagement necessary to prevent rotation during your most critical engine services. The Necessity of a Mechanical Lock When you're breaking loose crankshaft bolts or torquing a flywheel on a Detroit DD5, "holding it by hand" isn't an option.
