How to replace the rear Crankshaft Seal in a four cylinder engine on Mercury Capri?

Remove the transmission and all other components necessary, such as the clutch and pressure plate, to access the oil seal in the back of the engine. Next, remove the flywheel. Use a small punch to create two holes on opposite sides of the seal and install small sheet metal screws in these holes. Pry on the screws with two large screwdrivers until the seal is removed from the engine, taking care to place small blocks of wood against the block to provide a fulcrum point for prying, while avoiding any scratches or damage to the crankshaft oil seal surface. Apply a thin film of engine oil to the outer edge of the new seal, the seal bore in the block, and the seal lips. Position the seal on a special tool, available at most auto parts stores, and then place the tool and seal at the rear of the engine, installing the seal with the spring side toward the engine and alternating the tightening of the bolts to seat the seal in the block. If a special seal installer is not available, work the seal into place and gently tap it into the bore with a soft-face hammer, using the drive end of a socket extension or another blunt, smooth object to ease the lip of the seal over the end of the crankshaft. The remainder of the installation follows the reverse of the removal procedure.

How to replace rear Crankshaft Seal on Mercury Lynx?

Disconnect the battery negative cable, then remove the transaxle. Unbolt and take off the rear cover plate, followed by the removal of the flywheel/driveplate. Use a suitable hooked tool to pry out the oil seal from the cylinder block, taking care to avoid damaging the oil seal bore in the engine block. Grease the lips of the new seal and press it into position using a special tool or, if unavailable, tap it in squarely with a blunt punch and hammer, ensuring not to damage the seal or crankshaft. As the seal is installed, work the seal lip over the end of the crankshaft with the rounded end of a socket extension or a similar tool. The installation process is the reverse of removal, and after completing the installation, run the engine to check for oil leaks.

Mercury Crankshaft Seal prevents the leakage of oil and maintains the engine greased with unending dependability. Mercury has been in the middle of the bare transport/luxury since 1938 selling cars that rode smooth and looked sharp. The messenger picture of Romans was an allusion to the thin-slicing and the thin-sliding. Display rooms were shoved along with spacious cabins, muted interiors and instantly responsive steering in the congested streets. Drivers were fond of the soft suspension which actually absorbed bumps but did not kill road feel and proved that Mercury could be fun and comfortable. Value remained focus as Cougar and Grand Marquis moved forward without losing customary confidence. Although production was ceased in 2011 the Mercury badge continues to convey the indication of balanced design that has not forgotten the ease of everyday. The Crankshaft Seal (placed at the crank nose) prevents pressurized oil and the shaft turns thousands of times per minute keeping the bearings lubed and temperatures low. A damaged Crankshaft Seal may spray oil onto belts, cause pressure drop, and welcome the disaster of metal-on-metal grind. The metal-rubber compound contained within this Crankshaft Seal bends with increase in rpm and prevents sharp edges from cutting grooves in the crank. In both old and new Mercuries, Crankshaft Seal swaps are simply clamped into position and lubrication paths are immediately restored.
