Sinotruk HOWO Transmission Output Oil Seal WG9003071105 – For HW15710HW19710 Gearbox

A leaking gearbox is more than just a mess on the chassis; it’s a recipe for transmission failure. The WG9003071105 Oil Seal is the genuine output shaft seal designed for Sinotruk HOWO trucks equipped with the standard HW15710 and HW19710 series gearboxes.

Transmission seals endure incredible friction and heat. Inferior rubber seals often harden and crack after a few months of heavy hauling, leading to gear oil loss and potential bearing damage. This OEM-spec seal is crafted from high-quality Fluororubber (FKM) or reinforced Nitrile, specifically formulated to maintain elasticity even at high operating temperatures. It features a double-lip design: the primary lip holds the oil in, while the secondary dust lip keeps road grime and sand out of the housing.
