This is a Genuine Tecumseh OEM oil seal, part number 36301, supplied as New Old Stock (NOS). That means it is an original Tecumseh factory part that has never been used — not a reproduction or aftermarket substitute.
Oil seals play a critical role in Tecumseh OHV engines by preventing oil from leaking out around the crankshaft. Worn or hardened seals cause oil loss, contamination, and eventual engine damage. Using a true OEM Tecumseh seal ensures correct fit, proper sealing pressure, and long service life.
This seal is used on multiple Tecumseh OHV vertical-shaft engines, including lawn mowers, pressure washers, and other outdoor power equipment.
Why OEM matters
Aftermarket seals are often made from lower-grade rubber and incorrect dimensions. Tecumseh OEM seals are built to exact tolerances to handle engine heat, oil exposure, and crankshaft rotation without premature failure.
