The crankshaft gear designed for the OM904 Euro 4/5 engine plays a pivotal role in the timing system, ensuring precise synchronization between the crankshaft and camshaft. Constructed from durable steel, this gear features a robust tooth profile with 45 teeth, optimized for smooth power transfer and longevity under high-stress operation. Its specific dimensions, including a 12 mm width and an outer diameter of 131 mm, are engineered for perfect fitment within the engine's timing assembly. The inner diameter of 79 mm ensures secure mounting on the crankshaft, reducing the risk of slippage or misalignment that could compromise engine performance. The gear's precision manufacturing minimizes backlash, contributing to quieter operation and improved fuel efficiency. As a critical component in maintaining accurate valve timing, this gear helps prevent engine timing issues that could lead to decreased power output or mechanical failure.
