The Honda 90517-VD6-800 Pinion Gear Shim H (1.60MM) is a genuine OEM shim designed for H4514 and H4518 lawn tractors. As a direct Honda replacement, this shim is manufactured to the exact thickness specification required to set proper pinion gear positioning within the drivetrain. Honda supersedes parts at serial breaks, so confirm your tractor's serial number against the fitment table before ordering to ensure part number 90517-VD6-800 is the correct listing for your machine.
Key Features
- Exact Thickness Specification — at 1.60MM, this shim delivers the precise stack height needed to correctly position the pinion gear; using an incorrect thickness causes improper gear mesh and accelerated wear
- Genuine OEM Part — sourced directly from Honda, this component meets the same specification as the original installed at the factory, ensuring proper fit within the gear assembly
- Correct Fitment for H4514 and H4518 Lawn Tractors — listed for both H4514 and H4518 models; verify your serial number against the fitment table to confirm this is the right listing for your unit
A pinion gear shim is a precision-thickness spacer used to set the correct axial position and mesh depth of a pinion gear within a gear assembly. In a lawn tractor drivetrain, proper gear alignment is essential for smooth power transfer and even tooth contact — both of which directly affect how long the gears last. When a shim is worn, deformed, or of the wrong thickness, the gear mesh shifts out of specification, leading to noise, vibration, and premature gear wear that can progress into a more significant drivetrain repair.
