Product Overview

This high-quality Aftermarket Oil Pump Gear Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2025), XMAX 125 (2021-2025), and Tricity 125 (2021-2024) models.

The Oil Pump Gear Assy is the gear-driven assembly that transfers rotational power from the engine to the oil pump, ensuring continuous circulation of lubricating oil under pressure to all critical engine components. When the gear teeth become worn, chipped, or damaged, oil pump output becomes inconsistent, leading to fluctuating oil pressure, insufficient lubrication, and accelerated engine wear. This Aftermarket replacement is designed to match the original part, restoring consistent oil pump operation and reliable engine lubrication in your Yamaha scooters.

Complete Part Guide

Any drag or lash in the oil-pump drive can reduce lubrication pressure and oil flow when the engine is under load. This aftermarket Yamaha NMAX125 Oil Pump Gear Assembly (B6H-E3300-01) for 2021-2025 models drives the oil pump to maintain consistent lubrication where it matters most. Built as a trade-grade aftermarket replacement, it's engineered for fit and function, delivering steady operation and dependable performance. Direct fit installation with no modification, aligning perfectly with factory mounting points. Available now from Part Hive's London hub, order before 1 PM for same-day UK dispatch.

This is one of those small components that can affect the entire engine once it starts wearing. On the Yamaha NMAX-125, the oil pump gear is responsible for maintaining proper oil circulation throughout the system. We often see worn gears reducing oil flow consistency, which increases internal friction and operating temperature over time.

In workshop inspections, we check gear condition closely whenever lubrication-related wear is present. Left too long, the damage spreads beyond the gear itself. Fitting a trade-grade aftermarket Yamaha oil pump gear assembly restores proper oil pump drive and helps keep the lubrication system operating reliably.
