It prevents transmission fluid from leaking out while also keeping contaminants from entering the transmission. A worn or damaged input seal causes fluid leaks, potential bearing damage from fluid loss, and contamination of internal components.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to Replace:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInput seals should be replaced during transmission rebuilds, input shaft service, coupling replacement, or when experiencing fluid leaks at the input shaft area. Seals deteriorate over time due to heat, shaft rotation, fluid exposure, and normal wear. Signs of seal failure include visible fluid leaks at the bell housing area, low transmission fluid level, or fluid contamination. Always replace the input seal whenever the transmission is separated from the engine or coupling is removed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSeal Lip Protection:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe seal lip rides on the input shaft or coupling hub surface and must maintain constant contact to prevent leaks. A scored, grooved, or damaged shaft surface will cause premature seal failure. Always inspect the shaft seal surface for damage when replacing seals - if the shaft or coupling hub is damaged, it must be replaced or repaired before installing a new seal.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eClean seal bore thoroughly before installation. Inspect input shaft or coupling hub seal surface for grooves, scoring, or damage - repair or replace if damaged. Lubricate seal lip with clean transmission fluid before installation. Use proper seal installation tool to prevent damage and ensure seal is square and fully seated. Install with seal lip facing toward fluid side (inboard).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eService Best Practices:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNever reuse old seals - always install new seals during service. Ensure shaft or coupling hub surface is smooth and polished where seal lip rides. Check seal installation depth and orientation. Fill transmission with proper fluid and check for leaks after installation and engine-to-transmission alignment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Input shaft oil seal\u003c\/li\u003e\n\u003cli\u003eCompatible with: ZF marine transmissions\u003c\/li\u003e\n\u003cli\u003ePart Number: 0634319110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZFI","offers":[{"title":"Default Title","offer_id":43564308856868,"sku":"0634319110","price":68.62,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/0634319110.png?v=1771138744","url":"https:\/\/marisolmarine.com\/products\/zf-marine-transmission-input-seal","provider":"Marisol Marine Company","version":"1.0","type":"link"}
