The Honda 90518-VD6-800 Pinion Gear Shim I (1.65MM) is a genuine OEM Pinion Gear Shim designed for H4514 and H4518 lawn tractors. As a direct Honda OEM component, this shim is manufactured to the exact thickness specification required to achieve proper pinion gear alignment in the drivetrain. Confirm fitment using the serial number on your machine against the compatibility table before ordering, as Honda supersedes parts at serial breaks and the correct shim thickness is critical to proper gear mesh.
Key Features
- Exact Thickness Specification — at 1.65MM, this shim sets the precise axial positioning of the pinion gear; even a small deviation in shim thickness can result in improper gear engagement and accelerated wear
- Genuine Honda OEM Part — sourced directly from Honda, this component meets the exact dimensional tolerances specified for the H4514 and H4518 lawn tractor drivetrain
- Drivetrain Accuracy — correct pinion gear shimming ensures smooth, low-noise power transfer through the transmission; incorrect shim selection leads to gear noise, backlash, and premature component failure
- Serial Number Verification Recommended — Honda updates drivetrain shim specifications at production serial breaks, so always cross-reference your tractor's serial number with the fitment table to confirm part number 90518-VD6-800 is correct for your unit
A pinion gear shim is a precision-thickness spacer positioned within the transmission or differential assembly to control the axial location of the pinion gear. By setting the correct gear mesh and backlash, it ensures that power is transferred smoothly and that gear tooth contact is properly distributed. When the shim is worn, missing, or of the wrong thickness, the result is abnormal gear noise, excessive backlash, uneven tooth wear, and ultimately transmission damage that can sideline the tractor entirely.
