Type T Front Crankshaft Oil Seal

The OEM Lexus 90311-40022 is a genuine Type T oil seal, specifically designed for the oil pump and commonly referred to as a front crankshaft seal. As a direct replacement part, it ensures a factory-fit installation. This seal is manufactured by Lexus, utilizing top-notch materials to meet high standards for reliability and durability. This part is compatible with a range of Lexus models, including the ES250 (1990-1991, 2.5L), ES300 (1992-2003, 3.0L/3.3L), ES330 (2004-2006, 3.0L/3.3L), RX300 (1999-2003, 3.0L), RX330 (2004-2006, 3.3L), RX350 (2007, 3.3L), and RX400h (2006-2008, 3.3L). It replaces Lexus part numbers 90080-31034, 90311-40006, and 90311-40013. Installation of the crankshaft seal involves several steps. For V6 engines like those in the RX350, the procedure may require the engine and transmission assembly to be detached. It is recommended to lubricate the edge of the new seal with engine oil or multi-purpose grease before installation. Proper alignment and driving the seal flush with the surface of the timing chain cover or retainer are crucial for correct sealing.
