The Nissan Stagea C34 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. This tubular dowel is positioned on the rear face of the RB26, RB25, or RB20 cylinder block in the lower machined hole near the transmission mounting surface. Measuring approximately 13mm long with a 13mm outer diameter and a hollow center, it is pressed into the block to protrude slightly, providing accurate alignment during engine-to-transmission installation.
The hollow design of this dowel ensures critical vertical plane stability, allowing proper input shaft seating, accurate clutch and flywheel alignment, and secure gasket sealing. Its slight flexibility accommodates installation tolerances while maintaining rigidity under torque, making it essential for the drivetrain integrity of high-performance applications like the Stagea C34 260RS. Misalignment at this joint can lead to clutch issues, leaks, or premature wear, highlighting the importance of using the correct OEM component.
This lower engine-to-transmission dowel is routinely inspected or replaced during engine rebuilds, transmission swaps, or high-performance upgrades. Choosing genuine Nissan parts from Terra Firma Automotive guarantees precise fitment, long-lasting durability, and reliable performance. Installing this dowel ensures your Stagea C34 260RS maintains optimal drivetrain alignment, protecting the integrity and longevity of your RB26DETT, RB25DET, or RB20DET engine.
