The Honda 90507-764-L31 Shoulder Washer is a genuine OEM component designed for the MM60 compact tractor. As a direct Honda OEM part, it is manufactured to the same standards as the original hardware installed at the factory. Honda supersedes parts at serial breaks, so confirm your tractor's serial number against the fitment table before ordering to ensure this is the correct version for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification for the MM60 compact tractor.
- Exact Hardware Fit — the shouldered profile locates and retains components precisely, the way the original installation requires.
- Serial Number Verification Recommended — Honda issues part supersessions at production serial breaks; check your MM60 serial number against the compatibility table to confirm correct fitment.
A shoulder washer differs from a flat washer in that its raised collar — the shoulder — provides a defined bearing surface and helps locate the components it sits between. This geometry controls the clamping load, prevents over-tightening, and keeps the fastened parts correctly positioned during operation. When a shoulder washer is worn, deformed, or missing, that precise location is lost and the hardware it supports may shift or seat incorrectly.
