The Honda 76122-V09-D01 Tensioner Spring is a genuine OEM component designed for the HA4120 lawn tractor. As a direct Honda OEM part, it is manufactured to the exact specifications Honda requires for proper belt tension and drivetrain engagement on this machine. If your tractor is showing slipping, inconsistent blade engagement, or excessive belt wear, this spring is a common place to start. Verify part number 76122-V09-D01 against your serial number using Honda's fitment table before ordering, as Honda periodically supersedes parts at specific serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring matches the original tension rating and geometry specified for the HA4120, ensuring the belt drive system behaves exactly as designed.
- Direct Replacement — this part is a like-for-like swap for the original tensioner spring, with no modification needed to reinstall it on the HA4120 lawn tractor.
- Serial Number Matters — Honda updates part specifications at production breakpoints, so confirm your tractor's serial number aligns with part number 76122-V09-D01 before purchasing.
- Restore Proper Belt Tension — a fatigued or broken tensioner spring allows the drive belt to slip or disengage unpredictably; replacing it restores consistent engagement and normal cutting performance.
The tensioner spring maintains constant load on the belt tensioner arm, keeping the drive or blade belt taut during operation. Without adequate spring tension, the belt can slip under load, wear unevenly, or fail to engage altogether — leading to poor cutting performance or loss of drive function. Replacing a worn or broken tensioner spring is a straightforward service step that restores the belt system to normal operating condition on the HA4120 lawn tractor.
