Mercury E6DZ-1249-A Seal

Remove the axle shaft. The seal fits just inside the outer end of the axle shaft housing and ideally a slide hammer should be used to extract it. However, it can be removed using a hammer and chisel, but great care should be taken not to damage the axle housing. otherwise oil will seep past the outside of the new seal. Make a note of which way round the seal is located in the house before removing it; usually the metal clad side of the seal faces toward the roadwheel. Smear some gasket sealer around the outside casing of the new seal and drive it evenly into place using a block of wood or a tubular drift having the same outside diameter as the seal. Using a hammer and sharp chisel, make several deep nicks in the bearing retainer ring. This will release its grip on the axle shaft and allow it to be slid off the shaft. If it is tight however, split with a sharp chisel. Place the axle shaft upside-down in a vise so that the bearing retainer is on the top of the jaws and the axle shaft flange is under them, and using a soft-faced hammer drive the axle shaft through the bearing. If this proves difficult it will be necessary to use a garage press. Note which way round the bearing is fitted. Place the retainer plate and new bearing (correct way round) on the axle shaft. Place the axle shaft vertically between the jaws of a bench vise -flange uppermost, so that the inner track is resting on the top of the vise jaws. Using a soft-faced hammer, drive the axle shaft through the bearing until it is seated fully against the shaft shoulder. The bearing retainer should next be refitted, the sequence for this being the same as for the bearing. Do not attempt to fit the bearing and retainer at one go. Pack the bearing with a little multi-purpose grease. Refit the axle shaft assembly.

Remove the axleshaft. Sheer the old oil seal off the end of the axle housing. On later models, it can be done with a large screwdriver or inner end of the axleshaft; if the seal removal tool is not available, prybar or end of the axle can be used to pop the seal out of the housing. Some of the early models may need the use of a special slide hammer puller or other equivalent tool. With the lips in an inward position, the metal face should be visible from one end of the axle housing; to install the seal, one can use large socket or a piece of pipe, of a diameter lesser than the od of the seal. On extending axle housing by new part or by machining operation, the face of the oil seal should project to the end surface of the new part or machined surface. Screw the ring of the seal with the gear oil gently and smooth all the lips of the seal. Installation of the axleshaft then takes place.

Use a seal removal tool or the inner end of the axleshaft itself as a lever to pry the old oil seal out of the end of the axle housing.

When correctly installed, the face of the oil seal should be flush with the end of the axle housing.
