Key Features
- Genuine OEM Sizing — sourced directly from Honda, this washer carries the exact 14X45 dimensions specified for the GCV160 engine and HRR216 and HRS216 mowers, so it seats and clamps as the original design intends
- Direct Replacement — a drop-in swap for the original washer with no reworking of fasteners or mating surfaces required
- Broad Fitment — listed for GCV160 vertical shaft engines, HRR216 lawn mowers, and HRS216 lawn mowers; confirm your serial number against the fitment table to select the correct part for your unit
- Serial-Range Awareness — Honda supersedes hardware at production breaks, so checking your machine's serial number against the compatibility table is the surest way to confirm this is the right washer for your build
A washer distributes the clamping load of a fastener across a wider surface area, protecting the material beneath and preventing the fastener from pulling through or distorting a softer surface. In engines and mowers, washers maintain the correct clamping force on assembled components over extended service, keeping joints secure through vibration and thermal cycling. When a washer is the wrong size or missing entirely, fasteners can loosen prematurely or damage the surfaces they are meant to protect.
