Description
Overview:
The Exhaust Valve Spring Retainer is a Genuine Honda component for GX-series petrol engines, including GX240UT1 and GX340UTI1. Manufactured from durable, precision-machined steel, it sits at the top of the exhaust valve spring to keep the spring correctly located under load and heat. This ensures stable valve timing, smooth running and dependable performance in demanding conditions. The retainer is a direct-fit replacement within the cylinder head assembly and is built to withstand vibration and high temperatures common in compact industrial engines. It helps protect against premature wear of the valve train and supports consistent compression and exhaust flow. Genuine Honda part number 14773-Z8S-000 (also noted as 14773 Z8S 000) for assured compatibility and long service life in professional and domestic machinery.
