Specifications

Mahle Clevite 2231846 is an OE-equivalent piston wrist pin engineered for Caterpillar heavy-duty diesel platforms. Used in pistons for the 3406, 3406E, and C15 families, this pin is manufactured from high-strength, hardened steel and precision finished to support stable piston motion under extreme combustion and inertia loads. Proper wrist-pin geometry is critical for quiet operation, ring sealing, and cylinder life, especially in Cat engines that see sustained high torque. If you’re rebuilding a CAT 3406-series or C15, 2231846 provides the correct OE-matched fit and durability.
