The Honda 23453-743-000 Countershaft Second Gear (37T) 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 exact tooth count and dimensional specification required for proper engagement within the transmission. This part is confirmed for HS522 and HS622 snow blowers — always cross-reference your unit's serial number against the fitment table to confirm you have the correct version for your production range, as Honda supersedes parts at serial breaks.
Key Features
- Genuine OEM Gear Integrity — manufactured by Honda with the correct 37-tooth profile to maintain proper gear mesh, drive ratio, and smooth power transfer through the snow blower's transmission
- Exact Replacement for Second Gear Position — replaces the countershaft second gear directly, restoring correct drive engagement without any modification to the drivetrain
- Fits HS522 and HS622 Two-Stage Snow Blowers — sourced from Honda's own parts catalogue for these specific models; check your serial number against the fitment table to confirm applicability
- Transmission Performance — a worn or damaged second gear causes slipping, grinding, or loss of drive selection, leaving the machine unable to maintain consistent forward or reverse movement through heavy snow
The countershaft second gear is a core element of the two-stage snow blower's transmission, transferring engine power to the drive wheels at the correct speed and torque ratio for the selected gear. It meshes with the main shaft gearing to provide one of the forward or reverse drive speeds the operator selects. When this gear wears or breaks — through normal use, contaminated oil, or impact — the affected drive range becomes unreliable or fails entirely, reducing the machine's ability to propel itself through demanding conditions. Replacing it with the correct OEM gear restores full, predictable drive performance.
