The Honda 90510-751-000 Pinion Gear Shim A (36X43.5X1.25) is a genuine OEM component designed for H3011 riding mowers and H4013 lawn tractors. As a direct Honda replacement, this shim is manufactured to the exact dimensions Honda specifies — the 36X43.5X1.25 size designation is critical, and buyers should verify it matches their machine's requirement before ordering. Sourced directly from Honda, part number 90510-751-000 ensures the correct fit for the drivetrain assemblies found in these machines.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring this part meets the exact dimensional tolerances the drivetrain requires
- Critical Size Variant — the (36X43.5X1.25) designation identifies this specific shim thickness and diameter; confirm this matches your machine's specification before installing
- Fits H3011 and H4013 — listed for H3011 riding mowers and H4013 lawn tractors; verify your serial number against the fitment table to confirm the correct shim for your unit
- Gear Clearance Accuracy — proper shim thickness sets the correct axial positioning of the pinion gear; an incorrect or worn shim leads to excessive gear lash, uneven wear, or drivetrain noise
A pinion gear shim is a precision-thickness spacer that controls the axial position and mesh depth of a pinion gear within a drivetrain or transaxle assembly. By setting the correct running clearance between gears, this shim prevents excessive play and ensures smooth, efficient power transfer through the drivetrain of H3011 riding mowers and H4013 lawn tractors. When a shim wears thin, becomes deformed, or is replaced with an incorrect size, gear alignment shifts — leading to accelerated gear wear, drivetrain noise, or loss of drive engagement over time.
