The Honda 90511-VD6-800 Pinion Gear Shim B (1.30MM) is a genuine OEM Pinion Gear Shim designed for H4514 and H4518 lawn tractors. As a direct Honda OEM component, this shim is manufactured to the exact thickness specification required for correct pinion gear positioning in the drivetrain. Honda supersedes parts at serial breaks, so confirm your tractor's serial number against the fitment table before ordering to ensure this is the correct shim for your unit. This shim's 1.30MM thickness is a specific variant — if multiple shim listings appear for your model, match that dimension carefully to the specification your machine requires.
Key Features
- Exact Thickness Tolerance — at 1.30MM, this shim sets the precise axial clearance the pinion gear needs; even a small deviation in shim thickness causes accelerated gear wear or binding in the drivetrain
- Genuine Honda OEM Part — sourced directly from Honda, ensuring the thickness and material match what left the factory, so gear mesh and bearing preload remain within specification
- Fits H4514 and H4518 Lawn Tractors — listed for both Honda H4514 and H4518 models; verify your serial number against the fitment table, as Honda issues part supersessions at serial break points
- Variant Matching Required — Honda offers shims in multiple thickness grades; confirm the 1.30MM specification against your service manual or the original shim before installation
A pinion gear shim is a precision-thickness spacer used to control the axial position and mesh of the pinion gear within the drivetrain assembly of a lawn tractor. By setting the correct clearance between gears and bearings, the shim ensures that load is distributed evenly across the gear teeth, reducing wear and preventing noise or vibration during operation. When this shim is worn, crushed, or replaced with the wrong thickness grade, gear mesh becomes incorrect — leading to premature wear, gear noise, or loss of drive engagement in the tractor's transmission.
