The rocker shaft assembly for outlet valves and spacers plays an essential role in translating camshaft motion into valve actuation, ensuring precise timing and movement of the engine’s intake and exhaust valves. Constructed from durable thermoplastic, it combines strength with resistance to wear and thermal stress. Its dimensions, including an inner diameter of 36.10 mm and a height of 11.20 mm, are engineered for accurate fit and smooth operation. Proper functioning of this assembly is fundamental for maintaining optimal engine performance, fuel economy, and low emissions.
