Remove the driveplate. The Crankshaft Seal can be replaced without having to remove the oil pan or the seal retainer that is fitted in the engine. Still, the lip of the seal is quite rigid and the seal can be cocked in the retainer bore or damaged while being installed. Using a screwdriver gently remove the old rubber seal without scratching the surface of the crankshaft so that the new seal will not leak. Use multi-purpose grease on the crankshaft seal journal and lip of the new seal; insert the driver on the new seal with much care before hitting it until it is properly fixed. Lip is rather rigid and it should best be installed on the seal journal of the crankshaft gently. Insert the seal straight home and only home enough to make the seal level with back of seal plate while the spring side is facing inwards. The remaining steps are the, in essence, the reversal of the removal process described above.
