Toyota 90311-52022 Seal, Oil

Remove the seal on end-shaft block/cap and ensure the bore in this block/cap, bore in the new Crankshaft Seal, the contact surface of crankshaft is free from scratches, nicks which may damage the new seal lip and lead to oil leakage; if the crankshaft is damaged, then a suitable new crankshaft or different one has to be procured. As a matter of fact, engine oil or, better still, multi-purpose grease ought to be spread lightly on the outer lip of the new Crankshaft Seal besides spreading moly-base grease or engine assembly lube on the seal lip. Nice it the seal lip over the end of the crankshaft and gently drive it in using hammer and punch and make sure you have covered the bore through the circumference of the Crankshaft Seal making sure it is squarely seated.

Using a socket with an outside diameter slightly smaller than the outside diameter of the seal, carefully drive the new seal into place with a seal driver or large socket. Ensure it is installed squarely and to the same depth as the original. If a socket isn't available, a short section of large diameter pipe can also be used. After installation, check the seal to make sure the spring didn't pop out of place.

If you choose to proceed, pry out the old seal with a screwdriver, lubricate the crankshaft journal and the lip of the new seal with moly-base grease, and carefully press the new seal into place. Use multipurpose grease on the crankshaft seal journal and the new seal lip, and ensure to work the stiff lip onto the seal journal carefully.
