Nissan Pulsar GTiR RNN14 Transfer Case Locating Dowel (Lower) SR20

The Nissan Pulsar GTiR RNN14 Transfer Case Locating Dowel for the SR20DET is a precision-engineered hollow steel pin designed to ensure exact alignment between the engine block, transmission bell housing, and integrated transfer case. Positioned on the rear face of the SR20DET cylinder block in the AWD RNN14 GTiR, this tubular dowel measures approximately 20mm long with a 10mm outer diameter and a hollow center, protruding slightly to engage precisely with the transfer case housing during assembly. Its placement near the lower transmission mating area ensures the transfer case bolts correctly to the engine block, maintaining critical alignment across the drivetrain.

This dowel provides reliable positional accuracy for the transfer case, preventing misalignment that could cause binding in the torque-splitting mechanism, uneven power delivery, or fluid leaks in the Attesa E-TS system. The hollow construction allows slight flexibility during installation while preserving shear strength under torque, which is essential for consistent performance and longevity in high-stress AWD applications. Over time, these pins can wear or become damaged during service, making inspection or replacement a necessary step during AWD conversions, transfer case repairs, or full engine-transmission rebuilds.

Using genuine Nissan components from Terra Firma Automotive guarantees precise fitment, proper drivetrain alignment, and reliable performance. Installing the SR20DET Transfer Case Locating Dowel maintains smooth power transfer, protects internal drivetrain components, and ensures the RNN14 Pulsar GTiR operates at its intended efficiency and reliability.
