The Honda 90517-751-000 Pinion Gear Shim H (36X43.5X1.60) is a genuine OEM component designed for H3011 riding mowers and H4013 lawn tractors. As a direct Honda OEM part, it delivers the exact dimensional spec the drivetrain requires — the 36x43.5x1.60 size identifies this specific variant, so confirm that measurement against your machine before ordering. This Pinion Gear Shim H is sourced directly through Honda's parts network, ensuring the fit and function Honda engineered into these machines.
Key Features
- Exact OEM Dimensions — the 36x43.5x1.60 specification is the identifying factor for this variant; matching it precisely is essential for correct gear mesh and endplay in the drivetrain
- Genuine Honda Part — supplied as an authentic OEM component, manufactured to the same standard as the shim originally installed at the factory
- Correct Fitment — listed for H3011 riding mowers and H4013 lawn tractors; verify your machine's serial number against the fitment table to confirm this is the right shim for your unit
- Drivetrain Integrity — a shim at the incorrect thickness allows improper pinion gear engagement, which leads to accelerated gear wear and loss of smooth power transfer to the drive system
A pinion gear shim is a precision-thickness spacer positioned within the drivetrain to set the correct axial clearance and mesh depth of the pinion gear. By controlling how far the gear sits along its shaft, the shim ensures the gear teeth engage their mating component at the right contact point — too much clearance or too little causes uneven tooth loading, noise, and premature wear. When a shim is worn, deformed, or replaced with an incorrect thickness, gear mesh geometry shifts and the drivetrain loses efficiency and durability over time.
