The Nissan Laurel C33 Engine to Transmission Lower Locating Dowel is a precision-engineered hollow steel pin designed to ensure exact alignment between the engine block and transmission bell housing. Positioned on the rear face of the RB20 cylinder block in the lower machined hole near the transmission mounting surface, this tubular dowel measures approximately 13mm long with a 13mm outer diameter and a hollow center, protruding slightly to provide precise alignment during engine-to-transmission installation.
Its hollow design plays a crucial role in maintaining vertical plane stability, ensuring proper input shaft seating, accurate clutch and flywheel alignment, and secure gasket sealing. This slight flexibility allows for installation tolerances while maintaining rigidity under torque, making it essential for drivetrain integrity in performance applications. Misalignment at this joint can lead to clutch engagement issues, leaks, or premature wear, emphasizing the importance of using the correct OEM component.
Commonly inspected or replaced during transmission swaps, engine rebuilds, or performance upgrades, this lower engine-to-transmission dowel guarantees precise fitment and reliable operation. By choosing genuine Nissan parts from Terra Firma Automotive, Laurel C33 owners ensure long-lasting durability and consistent performance. Installing this dowel preserves proper alignment, protects drivetrain components, and maintains the integrity and longevity of the RB20 engine, making it an essential component for any rebuild or high-performance application.
