REPAIR INSTRUCTIONS

Installation

1.Remove the rear crankshaft oil seal from the flywheel housing by drilling two 3-mm holes, 180 degrees apart, into the outer edge of the seal. Remove the seal with a slide hammer fitted with a No. 10 sheet metal screw. Thread it into each of the holes alternately and work the seal free.

2.Using standard shop cleaning procedures for aluminum, clean the seal mounting surface.

3.Insert the two dowel pins in the cylinder block if they were removed. Refer to Figure 281.

The flywheel housing dowels maintain the alignment of the flywheel housing on the engine. This is necessary to center the transmission with respect to the engine flywheel and crankshaft. 281

4.Apply an even coat of Silastic® (approximately a 1/16-inch [2 mm] bead) to the flywheel housing mounting surface of the cylinder block. Refer to Figure 282. 282

5.Align the flywheel housing on the dowels and position it flush against the cylinder block surface. Refer to Figure 283. 283

6.Install the flywheel housing six internal mounting capscrews and tighten them finger-tight. Leave out the upper two external mounting capscrews, as they are installed later with the aftercooler bracket.

7.Tighten the six internal flywheel housing capscrews to the specified torque, 170 lb-ft (231 N•m), using torque wrench J 24407, or equivalent.
