The Honda 23412-743-000 Countershaft Gear (59T) is a genuine OEM component designed for HS522 and HS622 two-stage snow blowers. As a direct Honda OEM replacement, this gear is produced to the exact specifications of the original, ensuring the transmission delivers the torque and drive engagement your machine depends on. Confirm your snow blower's serial number against the fitment table before ordering, as Honda supersedes drivetrain parts at serial breaks. This part carries the 59-tooth count that defines this specific application — verify that specification matches your unit.
Key Features
- Genuine OEM Gear Geometry — manufactured by Honda to the precise tooth count (59T) and profile of the original, preserving correct gear mesh and load transfer through the countershaft assembly
- Direct OEM Replacement — sourced from Honda and engineered to drop into the existing drivetrain of HS522 and HS622 two-stage snow blowers without modification
- Serial Number Verification Recommended — Honda updates drivetrain components across production runs; cross-check your machine's serial number against the fitment table to confirm this is the correct gear for your unit
- Drivetrain Integrity — a worn or damaged countershaft gear causes slipping, missed engagement, or lost drive to the auger or wheels; replacing it restores full power transfer and keeps the machine clearing snow effectively
In a two-stage snow blower, the countershaft sits between the engine and the driven components — augers and wheels — and carries gears that step down speed and multiply torque. The Countershaft Gear (59T) meshes with mating gears in this assembly to transmit rotational power at the correct ratio. When the gear wears or chips, drive engagement becomes inconsistent, often showing up as sluggish auger rotation or erratic self-propulsion — symptoms that make clearing heavy snow difficult and put extra strain on the rest of the drivetrain. Replacing this gear with the correct genuine part restores smooth, consistent power delivery throughout the transmission.
