Toyota 9031138083 — Oil Seal (Front Oil Pump)
Overview
Oil pump seal Toyota 9031138083 seals the oil pump drive shaft and front crankshaft nose, preventing engine oil leaks from the lubrication system. Manufactured from fluororubber (FKM), this radial shaft seal withstands high oil temperatures, synthetic additives, and continuous friction. Technical dimensions measure 38 mm inner diameter, 50 mm outer diameter, and 6 mm width. The construction features an integrated dust lip and a garter spring to maintain uniform sealing lip tension against the rotating shaft surface. Original part number Toyota 9031138083 replaces cross-references 90311-38067, 90311-38089, Payen NJ839, and Musashi T1250.
This oil pump seal fits Toyota Corolla, Avensis, Celica, RAV4, Matrix, and MR2 models fitted with 1.6, 1.8, and 2.0 petrol engines from the 4A-FE, 7A-FE, 1ZZ-FE, and 3S-FE engine families produced between 1996 and 2008. Fit replacement parts when oil mist appears around the lower crankshaft pulley, during oil pump overhauls, or when changing timing belts contaminated by oil spray. Thermal hardening and mechanical wear cause the rubber lip to lose flexibility, creating oil seepage along the sealing surface. Fitting a new genuine seal maintains fluid retention inside the front timing cover and protects surrounding drive components.
