The Honda 90513-751-000 Pinion Gear Shim D (36X43.5X1.40) is a genuine OEM shim 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, 1.40 mm thickness — ensuring the correct gear mesh and axial clearance in the drive assembly. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes shim part numbers at specific serial breaks.
Key Features
- Exact OEM Dimensions — at 36 x 43.5 x 1.40 mm, this shim sets the correct axial position and running clearance for the pinion gear, preventing premature gear wear caused by improper mesh
- Genuine Honda OEM Part — sourced directly from Honda, part number 90513-751-000 is the correct replacement for the drive train on H3011 and H4013 machines
- Serial Number Verification Recommended — Honda updates shim specifications at production breaks; confirm your machine's serial number against the compatibility table to ensure this is the right thickness for your unit
- Drive Train Precision — a correctly specified shim keeps the pinion gear properly aligned and loaded; an incorrect thickness leads to gear noise, accelerated wear, and eventual drive failure
A pinion gear shim is a precisely dimensioned spacer used to set the axial position of the pinion gear within the drive assembly of a riding mower or lawn tractor. By controlling the gear's end-play and mesh depth, the shim ensures smooth, quiet power transfer and even load distribution across the gear teeth. When a shim is worn, deformed, or replaced with an incorrect thickness, gear alignment shifts, leading to increased noise, heat, and accelerated wear that can compromise the machine's drive system.
