The T66111 engine timing chain tensioner is an essential component of the Toyota Tundra, Sequoia, and Land Cruiser models produced between 2007 and 2017. This tensioner plays a crucial role in maintaining the correct tension on the engine's timing chain, ensuring proper engine timing and efficient operation.
The T66111 timing chain tensioner is a hydraulic unit, meaning it utilizes engine oil pressure to apply the necessary tension to the timing chain. The tensioner housing is made of durable cast aluminum, providing strength and resistance to the intense engine heat and vibrations. The tensioner pulley is engineered with a robust, ribbed design, enhancing its ability to effectively transmit power and tension to the timing chain.
The tensioner features a dual-lip seal design to prevent engine oil leakage, ensuring a clean and efficient engine compartment. The tensioner arm is constructed of high-strength steel, providing optimal tensioning force to the chain. The tensioner arm also includes a built-in roller bearing, reducing friction and wear on the tensioner and engine components.
The T66111 timing chain tensioner is designed to be a direct replacement for the original equipment on these Toyota models. Its installation is straightforward, requiring no additional modifications or adjustments to the engine. The tensioner comes complete with all necessary hardware, making it a convenient and hassle-free upgrade.
