The Honda 77228-340-003 Seat Lock Bar Cushion Rubber is a genuine OEM replacement designed for GX620 and GX670 horizontal shaft engines. As a direct OEM component sourced from Honda, this rubber cushion matches the original part exactly, ensuring the seat lock bar assembly functions as intended. Confirm your engine's serial number against the fitment table to make sure part number 77228-340-003 is the correct match for your specific unit.
Key Features
- Genuine OEM Rubber Compound — sourced directly from Honda, this cushion rubber meets the same material and dimensional standards as the original, maintaining proper seat lock bar contact and damping over time.
- Direct OEM Replacement — engineered to slot into the seat lock bar assembly without modification, restoring the fit and function Honda designed into these engines.
- Fits GX620 and GX670 Horizontal Shaft Engines — confirmed fitment for both Honda engine models; verify your serial number against the fitment table, as Honda supersedes parts at specific serial breaks.
The Seat Lock Bar Cushion Rubber serves as a buffer between the seat lock bar and its mounting point, absorbing vibration and preventing metal-to-metal contact that would otherwise cause wear, noise, or loosening of the assembly over time. On the GX620 and GX670 horizontal shaft engines, maintaining the integrity of this small rubber component keeps the seat lock mechanism seated and operating consistently. When the cushion rubber deteriorates or tears, the lock bar can shift, rattle, or fail to hold its position reliably during operation.
