The Honda 90519-751-000 is a genuine OEM Pinion Gear Shim J (36X43.5X1.70) designed for H3011 riding mowers and H4013 lawn tractors. As an authentic Honda part, it is manufactured to the exact dimensional specification — 36 mm inner diameter, 43.5 mm outer diameter, 1.70 mm thickness — ensuring the correct gear mesh and axial clearance within the drivetrain. This shim is listed for both the H3011 and H4013; verify part number 90519-751-000 against your machine's parts diagram before ordering, as shim selection is specific to the assembly stack in your unit.
Key Features
- Exact Dimensional Specification — the 36 x 43.5 x 1.70 mm sizing is precisely engineered to set correct pinion gear mesh and running clearance; an incorrect shim thickness introduces play or binding in the gear assembly
- Genuine Honda OEM Part — sourced directly from Honda, this shim carries the same specification as the original, so it drops into the assembly without the guesswork that comes with an unverified substitute
- Fits H3011 and H4013 — listed for H3011 riding mowers and H4013 lawn tractors; confirm fitment using your machine's parts diagram and serial number before installation
- Serial Number Verification Recommended — Honda updates drivetrain specifications at serial breaks, so check your machine's serial number against the fitment table to confirm this is the correct shim for your production run
A pinion gear shim is a precision-thickness spacer used to set the axial position and mesh engagement of a pinion gear within a gear assembly. By controlling how far the gear sits along its shaft, the shim determines the contact pattern between mating gears — too much or too little clearance causes accelerated wear, noise, or loss of drive. When the original shim wears, distorts, or is lost during a rebuild, replacing it with one of the correct thickness is essential to restoring proper gear alignment and smooth power transmission through the drivetrain of the H3011 or H4013.
