Remove the engine/transaxle assembly, then separate the transaxle from the engine. Remove the flywheel/driveplate. Use a seal removal tool or a screwdriver wrapped with tape to pry out the Crankshaft Seal, being careful not to gouge or nick the housing. Lubricate the crankshaft seal journal and the lip of the new seal with multi-purpose grease. Install the seal with the seal lip toward the engine and the dust seal toward the transaxle. Tap the seal into place using a seal driver to ensure it doesn't become tilted. Install the seal so that its rear edge is flush with the face of the engine block, or up to 0.019 inch recessed. The remainder of installation is the reverse of removal. Reconnect the battery and perform the necessary re-learn procedures.

Carefully drive the new seal into place using a seal driver or a socket slightly smaller than the seal's outside diameter, ensuring it is installed squarely and to the same depth as the original, while checking that the garter spring remains in place.
