MTU 5500500334 Exhaust Rocker Arm Assembly – Series 396 Diesel Engine

Product Overview

The MTU 5500500334 Exhaust Rocker Arm Assembly is a valve-train component designed for MTU Series 396 diesel engines. MTU parts documentation identifies 5500500334 as the exhaust rocker arm, while 5500500333 is the corresponding inlet rocker arm.

The exhaust rocker arm transfers mechanical movement from the engine’s valve-train mechanism to the exhaust valve, enabling the valve to open and close at the correct point in the combustion cycle. Proper rocker-arm operation is essential for correct valve timing, exhaust-gas discharge, engine efficiency, and reliable operation.

The part is documented across multiple Series 396 configurations, including 8V396, 12V396, and 16V396 engine variants.
