The Honda 90541-750-881 Lock Washer (0.375) is a genuine OEM replacement designed for DB1013 and HT3810 lawn tractors. Sourced directly from Honda, this washer matches the original specification for the fastener position it occupies, ensuring the same fit as the factory part it replaces. Because Honda supersedes hardware across serial ranges, confirm your tractor's serial number against the fitment table before ordering to make sure part number 90541-750-881 is the correct listing for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this Lock Washer (0.375) matches the original part it replaces with no guesswork on sizing or geometry.
- Correct Variant for Your Application — the 0.375 size qualifier identifies this specific washer; if your tractor's parts diagram lists more than one lock washer size, match this number to your diagram before ordering.
- Lawn Tractor Fitment — listed for the DB1013 and HT3810 lawn tractors; verify your serial number against the compatibility table, as Honda updates hardware part numbers at defined serial breaks.
A lock washer is a thin, hardened ring placed under a nut or bolt head to resist loosening caused by vibration and movement during operation. On a lawn tractor like the DB1013 and HT3810, drivetrain, deck, and chassis fasteners are subjected to sustained vibration, and a properly seated lock washer maintains clamping force over time. When a lock washer is missing or worn flat, the fastener it supports can work loose, leading to play, misalignment, or loss of a component at the mounting point.
