The Honda 90519-VD6-800 Pinion Gear Shim J (1.70MM) is a genuine OEM shim designed for H4514 and H4518 lawn tractors. As a Honda OEM component, this shim is manufactured to the exact thickness specification required to set proper pinion gear mesh and running clearance in 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 90519-VD6-800 is the correct listing for your unit.
Key Features
- Exact Thickness Specification — at 1.70MM, this shim provides the precise axial positioning needed for correct pinion gear mesh; using the wrong thickness can cause premature gear wear or drivetrain noise
- Genuine Honda OEM — sourced directly from Honda, this component matches the original part in material thickness and form, ensuring it drops into place without modification
- H4514 and H4518 Fitment — listed for both Honda lawn tractors; verify your serial number against the fitment table to confirm this is the correct shim variant for your machine
- Critical Drivetrain Clearance — shim selection directly affects how the pinion gear seats and loads; an incorrect or worn shim can lead to excessive backlash, noise, and accelerated gear wear
A pinion gear shim is a precision-thickness spacer used to set the correct axial position and mesh depth of the pinion gear within the drivetrain assembly. In a lawn tractor, proper gear mesh is essential for smooth, quiet power transfer to the drive wheels — if the shim is the wrong thickness or has worn down, the gear set runs out of alignment, which causes noise, vibration, and accelerated wear on both the pinion and its mating gear. Replacing this shim with the correct 1.70MM Honda OEM part restores the drivetrain to its specified running clearance.
