{"product_id":"4041958-retainer-vlv-sprg-intk","title":"4041958: RETAINER;VLV SPRG,INTK","description":"**Product Description: Valve Spring Retainers**\n\n**Function and Purpose:**\n- Valve spring retainers are essential components in an engine's valvetrain system.\n- They are fixed to the tip end of the valve to maintain the correct working height of the valve spring.\n- Works in conjunction with valve keepers to:\n  - Keep the correct pressure on the valve spring.\n  - Control the valvetrain by managing the force that varies as the valve is actuated by the camshaft.\n\n**Material and Construction:**\n- Typically made from high-strength materials like 4140 bar stock.\n- Heat-treated to achieve a hardness of 38-42 HRc.\n- May feature a protective coating to enhance durability.\n\n**Performance Considerations:**\n- Designed to withstand high stress, heat, and corrosion in the engine environment.\n- Critical for maintaining proper valve control and preventing valve float in high-performance applications.\n- Precision manufacturing is essential for tight tolerance control and excellent surface finish.\n\n**Installation and Fit:**\n- Proper fit with the valve spring is crucial for optimal performance and wear reduction.\n- Ideally, the retainer should have a line-to-line fit or slight interference (up to 0.005\") with the valve spring.\n- Should seat snugly on the valve stem and not rotate freely when assembled with valve locks.\n- Proper installation prevents side-to-side rocking of the retainer.\n\n**Maintenance:**\n- Regular inspection is recommended to check for small hairline fractures that can develop from stress.\n- Replacement of all valve spring retainers is advised to prevent potential catastrophic engine failure.\n\nThis valve spring retainer is a critical component for maintaining the integrity and performance of the engine's valvetrain system, particularly in high-performance applications.","brand":"HYSTER","offers":[{"title":"Default Title","offer_id":42753667170482,"sku":"HY-HY4041958","price":2.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/9630\/0696\/products\/White_and_Red_Round_Fitness_Logo404_a76a0fb3-9747-4796-bcf3-1fded56920aa.webp?v=1698616154","url":"https:\/\/www.motofork.com\/en-pe\/products\/4041958-retainer-vlv-sprg-intk","provider":"Motofork","version":"1.0","type":"link"}
