Manual Transmission Input Shaft Seal A purposebuilt seal designed to protect a manual transmission by sealing the point where the input shaft passes into the transmission housing. It stops fluid leaks, keeps contaminants out, and helps maintain correct fluid levels and pressure for reliable transmission performance. Key benefits Prevents transmission fluid leaks that can cause low fluid levels, excessive wear, noise, and shifting issues. Protects internal components from dirt and moisture, extending transmission and clutch life. Restores proper sealing when replacing a worn or damaged seal during routine service or clutch work. Simple, costeffective that avoids more extensive transmission damage and higher bills. Primary features and attributes Functionality: Seals the interface between the input shaft and transmission case to retain fluid and exclude debris. Compatibility: Intended for manual transmissions where an input shaft seal is required. Confirm fit with vehicle specifications before installation. Fit and performance: Engineered to provide a reliable lip seal under typical operating temperatures and rotational speeds encountered in manual transmissions. Serviceability: Designed for direct replacement of a worn or failing input shaft seal during transmission or clutch service. Use cases / applications Clutch replacement: the input shaft seal whenever the clutch or pilot bearing is serviced to ensure the transmission remains leak after reassembly. Leak : Use this seal to stop visible leaks at the transmission input shaft and prevent progressive fluid loss and drivability problems. Preventive maintenance: Install a input shaft seal when rebuilding or overhauling a manual transmission to restore original sealing performance. Installation notes and practices Inspect the input shaft, splines, and transmission housing sealing surface for nicks, burrs, or wear before installation; address any damage to ensure a proper seal. Lightly lubricate the seal lip with appropriate transmission fluid or assembly lube during installation to prevent dry starts and avoid damage to the sealing lip. Install square and flush with the housing using the correct driver or sleeve to avoid distorting the seal. seals as part of clutch or transmission service intervals for reliable longterm operation.
