The Honda 23451-743-000 Change Gear (17T-31T) is a genuine OEM component designed for HS522 and HS622 two-stage snow blowers. As a direct Honda OEM part, it is manufactured to the same specification as the gear originally installed at the factory, ensuring correct tooth count and mesh engagement within the drive system. This part is designed for the HS522 and HS622 models — always confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct gear can vary by production run.
Key Features
- Correct Tooth Geometry — the 17T-31T tooth specification is the defining detail of this gear; an incorrect tooth count will prevent proper mesh and damage the surrounding drivetrain components
- Genuine Honda OEM Construction — manufactured to Honda's original specification, so gear pitch, bore dimensions, and engagement geometry match what the transmission was designed around
- Fits HS522 and HS622 Two-Stage Snow Blowers — confirm your machine's serial number against the fitment table, as this gear applies to specific production ranges within these models
- Smooth Speed Transition — a correctly functioning change gear allows the operator to shift drive speeds cleanly; a worn or chipped gear causes rough shifting, slipping, or loss of drive engagement
The change gear is part of the transmission that controls ground drive speed on a two-stage snow blower. It meshes with adjacent gears in the gearbox to transfer engine power to the drive wheels, with its tooth ratio determining how speed and torque are delivered through each selected drive range. When the gear's teeth wear down or chip — common after seasons of heavy use — the transmission begins to slip or jump out of gear, reducing the operator's ability to control forward and reverse movement through deep snow.
