Mercury F3AZ-6701-B Seal Assembly - Crankshaf

Tighten the damper bolt to the specified torque.

The first step is to disconnect the cable from the negative battery terminal.

Apply a thin coat of engine oil to the outer edge of the new seal and apply moly-based grease to the seal lips.

The first step is to remove the transmission.

A special tool should be used to remove the crankshaft rear oil slinger.

With the plastic seal liner or tool in place, carefully move the new carrier (with seal factory-installed) into position by sliding it onto the contact surface of the crankshaft.

The seal installation can be performed more easily by unbolting and removing the seal retainer plate. Remove all the mounting bolts, then use two of the retainer-to-oil pan bolts and start them into the two threaded holes in the retainer plate. Tightening these two bolts alternately will push the retainer from the engine. Remove all traces of RTV sealant and apply a 3/16-inch bead of RTV where the block and oil pan flanges meet.

The one-piece rear main oil seal is pressed into a rear main oil seal carrier mounted at the rear of the block.

Remove the crankshaft pulley and, on 1.5L and 1.6L engines, remove the timing belt and crankshaft sprocket.

The seal can be reinstalled in either of two ways. Either use a special tool such as the one used by the manufacturer or the seal can be driven into the bore with a large socket and hammer until it's completely seated. Select a socket that's the same outside diameter as the seal (a section of pipe can be used if a socket isn't available).
