National Input Shaft Seal for 4-Speed Toploaders with a Small Input Shaft.
This is the seal at the front case of the transmission around the input shaft behind the throw out bearing retainer.
Eliminates bore leakage using a nitril seal with a proprietary RediCoat sealant. Patented lay-down sealing lip design ensures long life in spite of extreme temperatures, shaft imperfections, shaft/bore misalignment and excessive shaft thrust or movement.
