Toyota 90311-A0020 Seal, Type T Oil

You can Select Your Vehicle to check if 90311-A0020 fits your vehicle.

The first step is to remove the engine/transmission assembly from the vehicle.

Run the engine and check for oil leaks at the front seal.

The new seal should be evenly driven into the container using a wood block or a section of pipe slightly smaller in diameter than the outside diameter of the seal.

Wrap tape around the tip of the screwdriver to avoid scratching the housing bore or damaging the crankshaft, as this could cause the new seal to leak.

Install the flywheel or driveplate.

Remove the crankshaft pulley. Note how the Crankshaft Seal is installed; the new one must be installed to the same depth and facing the same way. Carefully pry the oil seal out of the cover with a seal puller or a large screwdriver. Be very careful not to distort the cover or scratch the crankshaft! Apply clean engine oil or multi-purpose grease to the outer edge of the new seal, then install it in the cover with the lip (spring side) facing in. Drive the seal into place with a seal driver or a large socket and a hammer. Make sure the seal enters the bore squarely and stops when the front face is at the proper depth. Check the surface on the pulley hub that the seal rides on. if the surface has been grooved from long-time contact with the seal. The pulley should be replaced. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley. Install the crankshaft pulley retaining bolt and tighten it to the torque. The remainder of installation is the reverse of removal.

The remainder of the installation is the reverse of the removal process.

Lubricate the outside diameter of the seal and install the seal over the end of the crankshaft, making sure the lip of the seal points toward the engine.
