The Nissan Skyline R32, R33, and R34 Engine to Transmission Lower Locating Dowel is a precision-engineered hollow steel pin designed to ensure accurate alignment between the engine block and transmission bell housing. This tubular locating 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, allowing precise alignment during engine-to-transmission installation.
This hollow dowel’s design provides essential vertical plane stability, ensuring proper seating of the input shaft, accurate clutch and flywheel alignment, and reliable gasket sealing. Its slight flexibility accommodates installation tolerances while maintaining rigidity under torque loads, making it critical for drivetrain integrity, particularly in high-performance applications such as the Skyline R34 GT-R. Misalignment at this joint can cause premature wear, clutch issues, or leaks, emphasizing the importance of using the correct OEM part.
The lower engine-to-transmission dowel is commonly inspected or replaced during engine rebuilds, transmission swaps, or high-performance modifications. Choosing genuine Nissan components from Terra Firma Automotive guarantees precise fitment, durability, and long-term reliability, ensuring your Skyline R32, R33, or R34 continues to perform at the highest level.
