Description
Overview:
This Genuine Honda Governor Assembly (16510-ZE3-000) is an OEM engine control component for Honda GX340 and GX390 series petrol engines. Built from a mix of robust metal parts and engineering‐grade polymer, it uses centrifugal force to regulate throttle position and keep engine speed consistent under changing loads. By preventing over‐speeding and stabilising RPM, it protects the engine and improves drivability of equipment. The assembly is a direct replacement for worn or damaged governor components and restores reliable speed control without modification. It is suitable for Honda-powered machinery such as generators, pumps, pressure washers and compactors that use GX340 or GX390 engines. Manufactured to Honda standards for fit and function, it helps maintain performance and longevity in everyday site and garden equipment.
Key Features:
- Genuine Honda OEM part for assured compatibility and quality
- Direct-fit replacement engineered for GX340/GX390 families
- Maintains steady RPM under load for smoother operation
- Helps prevent over‐speeding to safeguard the engine
- Durable metal and polymer construction for long service life
- Accurate factory tolerances for reliable, repeatable control
- Pre-assembled unit that is straightforward to install with standard tools
- Works with the original Honda governor arm and spring set
- Suitable for routine maintenance or full engine rebuilds
- Clear Honda part numbering for easy identification
Typical Applications:
Used during servicing or rebuilds of Honda GX340/GX390 engines in equipment such as site generators (including EC5000), water pumps, pressure washers, plate compactors, tillers and other light plant. Ideal where engines exhibit hunting, unstable RPM or poor load response due to worn governor components.
