The Honda 91555-V09-A01 Idler Pulley Bushing is a genuine OEM component designed for HA4118 and HA4120 lawn tractors. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a proper fit within the deck drive system of your tractor. Sourced directly through authorized Honda channels, this bushing carries the confidence of genuine Honda engineering for a lasting, trouble-free repair.
Key Features
- Genuine OEM Fitment — manufactured by Honda to match the original bushing dimensions exactly, so the idler pulley seats and rotates the way it did from the factory
- Correct Bearing Surface — maintains proper running clearance between the idler pulley and its mounting point, preventing premature pulley wear and belt misalignment
- Designed for HA4118 and HA4120 Lawn Tractors — confirm your tractor's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks
- Drive Belt Integrity — a worn or degraded bushing allows the idler pulley to wobble, causing uneven belt tension, belt slippage, and accelerated belt wear across the deck drive
The idler pulley bushing is a small but critical component in the deck drive system of the HA4118 and HA4120 lawn tractors. It sits inside the idler pulley and provides the bearing surface that keeps the pulley spinning smoothly on its mount, maintaining consistent tension and alignment of the drive belt. When this bushing wears or fails, the idler pulley loses its true running axis — leading to belt flutter, slippage, or premature belt failure — making timely replacement essential to keeping the cutting deck performing correctly.
