The Honda 91551-743-000 Input Shaft Gear Collar is a genuine OEM component designed for HS522 and HS622 two-stage snow blowers. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a direct, trouble-free installation. Honda supersedes parts at serial-number breaks, so confirm your machine's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Precision — sourced directly from Honda, this collar matches the exact dimensions of the original, maintaining correct gear engagement on the input shaft
- Direct Replacement — engineered to drop into HS522 and HS622 two-stage snow blowers without modification, restoring the drivetrain to proper operating condition
- Serial Number Matters — Honda updates parts at production breaks, so always cross-reference your snow blower's serial number with the compatibility table to confirm this is the correct collar for your unit
- Drivetrain Integrity — a worn or damaged collar can cause inconsistent power transfer through the input shaft gear assembly, leading to erratic auger or drive performance during demanding clearing conditions
The input shaft gear collar is a positioning and retention component within the drivetrain of a two-stage snow blower. It locates the input shaft gear precisely along the shaft, maintaining the correct spacing and alignment needed for smooth, consistent power transfer from the engine to the auger and drive systems. When this collar is worn, cracked, or missing, gear alignment is compromised, which can produce excessive play, noise, or loss of drive — leaving the machine unable to clear snow effectively.
