Toyota 90311-95012 Seal, Engine Rear Oil

Remove the transmission and the rear end plate. The Crankshaft Seal can be replaced without removing the oil pan or seal retainer, but this method is not recommended due to the stiffness of the seal lip, which may lead to improper installation or damage. If proceeding, pry out the old Crankshaft Seal with a screwdriver, apply multi-purpose grease to the crankshaft seal journal and the lip of the new Crankshaft Seal, and carefully press the new Crankshaft Seal into place, ensuring not to rush to avoid damage. A recommended method involves removing the seal retainer and resealing the rear of the oil pan. After removing the two rearmost oil pan-to-seal retainer bolts, break the seal between the rear of the oil pan and the bottom of the seal retainer with a putty knife, then detach the seal retainer and remove all old gasket material, ensuring to cover the open area of the oil pan with clean rags to keep debris out. Position the Crankshaft Seal and retainer assembly between two wood blocks on a workbench and drive the old Crankshaft Seal out from the back side with a screwdriver. Drive the new Crankshaft Seal into the retainer using a wood block or a section of pipe slightly smaller in diameter than the outside diameter of the Crankshaft Seal, ensuring it is not cocked in the retainer bore. Lubricate the crankshaft seal journal and the lip of the new Crankshaft Seal with multi-purpose grease, applying a 2 to 3 mm wide bead of RTV sealant to the retainer flange before attaching it to the block, as there is no gasket between the seal retainer and the engine block. Carefully push the Crankshaft Seal and retainer onto the crankshaft, using a smooth object to assist with the stiff seal lip, and then install and tighten the retainer bolts to the specified torque. The remainder of the installation follows the reverse order of removal.

Reinstall the crankshaft pulley, tightening the bolt to the specified torque.

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

The easiest method involves using a seal-removal tool. If this tool isn't available, a sharp knife can be used to cut the lip off the old seal while carefully avoiding scratching the crankshaft. After the lip is gone, a screwdriver wrapped with tape can be used to pry the seal out.

Carefully pry the seal out of the engine with a screwdriver or seal removal tool. If using a screwdriver, wrap tape around the tip to avoid scratching the housing bore or damaging the crankshaft.

Drive the new seal into the retainer using a wood block or a section of pipe that is slightly smaller in diameter than the outside diameter of the seal. Ensure that you do not cock the seal in the retainer bore.
