Key Features
- Genuine OEM Construction — sourced directly from Honda, this washer meets the same dimensional and material specification as the original part it replaces, ensuring consistent performance in your tractor's drivetrain.
- Correct 23MM Sizing — the 23MM spline washer specification is critical; using an incorrect size can result in improper load distribution or premature wear, so match this part to your machine's requirement before installing.
- Broad Tractor Compatibility — listed for the H5013, H5518, and RT5000 multi-purpose tractors, covering a range of Honda's heavier-duty tractor lineup.
- Serial Number Verification Recommended — Honda supersedes parts across production runs, so check your tractor's serial number against the compatibility table to confirm this is the correct washer for your unit.
A spline washer seats against a splined shaft or component to distribute load, maintain proper spacing, and prevent unwanted axial movement within a drivetrain assembly. In multi-purpose tractors like the H5013, H5518, and RT5000, this type of washer plays a quiet but important role in keeping rotating components properly located under working loads. When a spline washer wears down or is missing entirely, the components it supports can shift out of position, leading to accelerated wear on mating parts and reduced drivetrain reliability.
