SEAL - FRONT CRANK (Toyota TY11311U316071)

A damaged front crank seal can allow oil to escape past the rotating shaft, leading to visible leaks and potential contamination of adjacent components. This aftermarket replacement part references the Toyota catalog number TY11311U316071. The seal functions as a stationary barrier that contacts the crankshaft surface to retain lubricant inside the crankcase. Over time, the sealing lip may harden or wear, causing gradual seepage that reduces oil levels. A worn seal often results in oil drips beneath the vehicle during parking or after shutdown. The item ships at approximately 0.064 pounds. Verify the serial number or application, then call (562) 693-7748.
