The Honda 76122-751-000 Tensioner Arm Spring is a genuine OEM replacement designed for CD3009, CD3811, and H3011 riding mowers. As a direct Honda OEM component, this spring is manufactured to the exact specification Honda engineers set for these machines, ensuring the tensioner arm operates exactly as intended. Confirm your mower's model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct spring depends on your specific production range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring meets the original design specification for the CD3009, CD3811, and H3011 riding mowers, with no guesswork about rate or geometry.
- Consistent Tensioner Arm Action — the spring maintains correct load on the tensioner arm so belt engagement stays predictable and the drive system responds as designed.
- Broad Riding Mower Coverage — a single part number covering CD3009, CD3811, and H3011 riding mowers, making it a straightforward replacement across Honda's CD and H series riding mower lineup.
- Serial Number Verification Recommended — Honda updates part numbers at production breaks, so cross-check your mower's serial number against the compatibility table to confirm this is the right spring for your unit.
The tensioner arm spring maintains constant pressure on the belt tensioner arm, keeping the drive belt at the correct tension throughout operation. Without sufficient spring tension, the belt can slip or disengage under load, causing erratic or lost drive performance. A worn or broken spring allows the tensioner arm to go slack, leading to belt wear, slipping, or failure to engage — replacing it restores proper belt control and keeps the mower's drive system operating as Honda designed it.
