The Honda 90521-VD6-801 Bevel Gear Shim B (2.40MM) is a genuine OEM Bevel Gear Shim B (2.40MM) designed for H4514 and H4518 lawn tractors. As a direct Honda OEM component, this shim is manufactured to the exact dimensional specification required to maintain proper bevel gear mesh and drivetrain geometry in these tractors. Confirm your serial number against the fitment table before ordering, as Honda supersedes shim part numbers at production breaks and the correct thickness is critical to proper assembly.
Key Features
- Exact Thickness Specification — at 2.40MM, this shim sets the precise axial clearance in the bevel gear assembly; using the wrong thickness risks premature gear wear or binding in the drivetrain
- Genuine Honda OEM — sourced directly from Honda, this component meets the exact dimensional tolerances specified for H4514 and H4518 lawn tractor assemblies
- Serial Number Matters — Honda updates shim specifications at production breaks, so always verify your tractor's serial number against the compatibility table to confirm this is the correct shim for your unit
- Correct Fitment — listed for H4514 and H4518 lawn tractors; match the 2.40MM thickness to your machine's service specification before installation
A bevel gear shim is a precision-thickness spacer used to set the correct axial position and mesh depth of the bevel gears within a tractor's drivetrain. Getting this dimension right is essential: too little or too much clearance causes the gears to mesh improperly, leading to noise, vibration, and accelerated wear on the gear teeth. When a shim is worn, damaged, or replaced with an incorrect thickness during service, the bevel gear assembly loses the alignment it depends on and drivetrain performance deteriorates quickly.
