Fits many Cummins 6BT, 6BTA, John Deere, Caterpillar (Cat), and other diesel boat engines that are standard rotation and have an SAE 11.5 flywheel. For use with 26-spline input shaft, common to many ZF, Hurth, Velvet Drive, and other transmissions. Handles up to 738 lb-ft of torque. Dimensions are 13.126 inch (333.4 mm) bolt center-to-center, 13.874 inch (352.4 mm) overall outside diameter (OD). 8 bolt holes.
Installation note: These are designed for standard-rotation engines only (left-hand, counter-clockwise when viewing the flywheel). The plate must be installed with the arrow showing the direction of rotation. The arrow and part number stamped onto the plate should be facing out from the engine (towards transmission). Incorrect installation will cause the damper to break apart.
