The Honda 90412-PA9-010 Spline Washer (35X50X3.05) is a genuine OEM component designed for the H6522 compact tractor. As a direct Honda OEM part, this washer carries the exact dimensions — 35 mm inner diameter, 50 mm outer diameter, 3.05 mm thickness — specified for this application, ensuring it seats and functions as intended. Honda supersedes parts at serial breaks, so confirm your machine's serial number against the fitment table before ordering to ensure part number 90412-PA9-010 is the correct version for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda's parts catalogue.
- Sized to Specification — the 35X50X3.05 variant identifier is the critical match point; verify it against your existing washer before fitting
- Serial Number Awareness — Honda issues updated part numbers at production serial breaks; cross-reference your tractor's serial number with the fitment table to confirm this is the correct version for your machine
- H6522 Fitment — listed for the H6522 compact tractor; this part is not a universal washer and should only be installed where the fitment table confirms compatibility
A spline washer is a precision flat washer sized to interface with a splined shaft or bore, distributing clamping load evenly across the mating surface while maintaining correct axial positioning of the assembled components. In a compact tractor like the H6522, these washers are used where tight dimensional tolerances matter — a washer of the wrong thickness or diameter will not seat flush, which can allow movement, uneven load distribution, or improper preload in the assembly. Replacing a worn or damaged washer with the correct OEM part restores the intended clamping and seating behavior to keep the assembly performing as designed.
