MTU 5500500334 Exhaust Rocker Arm Assembly – Series 396 Diesel Engine

Product Overview

The MTU 5500500334 Exhaust Rocker Arm Assembly is a valve-train component used on MTU Series 396 diesel engines. Parts documentation identifies 5500500334 specifically as the exhaust rocker arm, paired with inlet rocker arm 5500500333.

The rocker arm transfers mechanical movement from the engine’s pushrod/valve-train mechanism to the exhaust valve, allowing the valve to open and close according to the engine’s timing cycle. Because it operates repeatedly under engine load, correct rocker geometry, bushings and adjustment are important for proper valve operation.

Parts catalogs show 5500500334 in several Series 396 configurations, including 8V396, 12V396 and 16V396 applications; exact compatibility should still be confirmed using the engine model and serial number.
