The Honda 90523-VD6-801 Bevel Gear Shim D (2.50MM) is a genuine OEM shim designed for H4514 and H4518 lawn tractors. As a Honda OEM component, this shim is produced to the exact dimensional specification required for correct bevel gear stack height in these tractors. Confirm your tractor's serial number against the fitment table before ordering, as Honda may supersede this part at specific serial breaks.
Key Features
- Exact 2.50MM Thickness — the dimensional grade of this shim is what sets correct bevel gear mesh and preload; selecting the right thickness is essential to drivetrain function
- Genuine Honda OEM — sourced directly from Honda's parts supply, ensuring the shim matches the original specification for H4514 and H4518 lawn tractors
- Serial Number Verification Advised — Honda assigns specific shim grades by serial range, so always cross-reference your tractor's serial number with the fitment table to confirm part number 90523-VD6-801 is correct for your unit
- Drivetrain Precision — correct gear shimming keeps the bevel gear set running smoothly and quietly; an incorrectly shimmed gear set can result in premature gear wear or noisy operation
A bevel gear shim is a precision-thickness spacer used to set the correct axial position and mesh engagement of bevel gears within the tractor's drivetrain. In the H4514 and H4518 lawn tractors, this shim establishes the working clearance and preload in the bevel gear assembly, directly affecting how smoothly and efficiently power is transferred through the drivetrain. When a shim of the wrong thickness is installed — or when a shim is worn, deformed, or missing — bevel gears can run out of optimal mesh, leading to increased noise, vibration, and accelerated gear wear over time.
