Toyota 90311-A0005 Oil Seal

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 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 remove the retainer-to-engine block bolts, detach the seal retainer, and clean off all old gasket material and sealant from the oil pan flange, covering the open area 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 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, 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, position a new gasket on the engine block, and apply a bead of RTV sealant to the exposed portion of the oil pan flange, particularly at the pan-to-block mating surface. Slowly and carefully push the Crankshaft Seal and retainer onto the crankshaft, using a smooth object to assist with the stiff seal lip, and install and tighten the retainer bolts to the specified torque. The remainder of the installation follows the reverse order of removal.
