The Honda 73551-743-000 Driven Gear (55T) is a genuine OEM component designed for HS522 and HS622 two-stage snow blowers. As a direct Honda OEM replacement, this gear is manufactured to the same specification as the original, ensuring correct tooth count and dimensional accuracy for proper mesh and load transfer. This part is built for HS522 and HS622 models — verify your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one version of this gear may exist across the production run.
Key Features
- Genuine Honda OEM — sourced directly from Honda, matching the original 55-tooth specification for correct gear engagement and drive ratio in the snow blower's auger or drive system.
- 55-Tooth Count — the tooth count is a critical match point; installing a gear with the wrong number of teeth will cause improper meshing, accelerated wear, and loss of drive.
- Confirmed Fitment — designed for HS522 and HS622 two-stage snow blowers, including models across multiple serial ranges.
- Serial Number Check Recommended — Honda updates parts at specific serial breaks; confirm your machine's serial number against the compatibility table to ensure this is the correct version for your unit.
In a two-stage snow blower, driven gears are part of the gear train that transfers power from the engine to the auger or drive wheels, converting and transmitting rotational force at the correct speed and torque. The 55-tooth count on this gear determines the gear ratio in that drivetrain, directly affecting how efficiently the auger or drive system operates under load. When a driven gear wears or loses teeth, drive becomes inconsistent or fails altogether — restoring it with the correct OEM replacement brings the snow blower back to its designed operating performance.
