14. Independent Product Description
This rugged marine pinion bevel gear serves as a reliable aftermarket replacement matching OEM part number 3B7‑64020‑0 and cross‑reference 3B7‑64020‑1. It is engineered for Nissan 6HP outboard motors of NS4, NS5B, NSF4, NSF5 and NSF6 series for lower‑unit transmission repair. Built from wear‑resistant quenched alloy steel, this component goes through accurate CNC machining alongside thorough heat‑treatment steps. Its solid construction maintains steady structural rigidity under continuous torque loads and salt‑spray marine surroundings. Hardened bevel gear teeth hold up against chipping and scuffing during repeated forward‑reverse gear shifts. Every shaft‑hole measurement and spline dimension closely meets OEM tolerance benchmarks. Fitters can complete quick, exact installation, and no trimming or secondary rework is necessary. This practical service‑grade aftermarket part resolves common gear‑case troubles, such as choppy power transmission, grinding gear noise, gear jumping and heavily worn‑down tooth surfaces. Swapping out the aged pinion gear restores stable power transfer inside your outboard gear case. Be sure to refer to the official factory service manual for proper mounting and gear‑oil top‑up. Once assembled correctly, your Nissan outboard will deliver reliable power‑output performance on open water.
