The Honda 90411-744-000 Conical Spring Washer (6mm) is a genuine OEM replacement designed for a wide range of Honda tillers, engines, tractors, and power carriers, including the GX160, FG500, F401, F501, H5013, H5518, H6522, HP250, HP400, RLK5000, and RT5000. As a Honda OEM part, it matches the original specification exactly, so no guesswork is required when sourcing a direct replacement. Always verify your machine's serial number against the fitment table, as Honda updates part numbers at production breaks and fitment can vary by serial range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification for correct clamping load and spring deflection.
- Broad Fitment — listed for GX160 horizontal shaft engines, FG500, F401, and F501 tillers, H5013, H5518, H6522, RLK5000, and RT5000 tractors, and HP250 and HP400 power carriers.
- Verify by Serial Number — Honda supersedes fastener hardware at production breaks; confirm your machine's serial number against the compatibility table before ordering.
- Correct Spring Action — the conical profile delivers controlled axial load under fastening, maintaining consistent clamp force even under vibration or thermal cycling.
A conical spring washer — sometimes called a Belleville washer — sits beneath a fastener and uses its dished, cone-shaped profile to maintain clamping force as the joint experiences vibration or temperature changes. Unlike a flat washer, it acts as a spring, compensating for minor relaxation in the fastener stack and keeping the assembly secure under working conditions. When a conical spring washer flattens, deforms, or is omitted entirely, the fastener it supports can gradually loosen, which allows joint movement and the wear or misalignment that follows.
