The valve plate springs maintain constant seating pressure between the valve plate and the cylinder block rotor, ensuring a leak-free hydraulic seal during operation. Fatigued or broken springs result in internal bypass, loss of hydraulic pressure, and reduced swing torque — making this set essential for any thorough swing motor rebuild.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFull set of 4 springs for a complete valve plate rebuild\u003c\/li\u003e\n\u003cli\u003eMaintains consistent seating pressure for leak-free valve plate operation\u003c\/li\u003e\n\u003cli\u003eCompatible with MFB80, SG04, and SG04E swing motor assemblies\u003c\/li\u003e\n\u003cli\u003eManufactured to precise spring rate specifications for reliable performance\u003c\/li\u003e\n\u003cli\u003ePrevents internal hydraulic bypass and restores full swing torque output\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eSwing Motor Models: MFB80, SG04, SG04E\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e4 × Valve Plate Springs\u003c\/li\u003e\u003c\/ul\u003e","brand":"Fab Heavy Parts","offers":[{"title":"Default Title","offer_id":41832973500549,"sku":"FN26081418","price":731.0,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0373\/4886\/8229\/files\/mfb80-sg04-sg04e-swing-motor-valve-plate-spring-set-of-4fab-heavy-parts-3992569.webp?v=1788292696","url":"https:\/\/www.fabheavyparts.com\/en-br\/products\/mfb80-sg04-g04e-spring-for-valve-plate-swing-motor-4-pcs","provider":"Fab Heavy Parts","version":"1.0","type":"link"}
