Remove the flywheel front adapter. 5. NOTICE: To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is removed and reinstalled, it will result in engine vibration and premature transmission component wear. NOTICE: Drill only deep enough to penetrate the seal. Engine damage will occur if the seal is drilled too deep. NOTE: On original service seals, if equipped, the wear ring will be removed separately. Using a center punch, mark a location for 2 holes 180 degrees apart, 9.53 mm (0.375 in) from the outer diameter of the crankshaft flange. Using a drill bit of the appropriate size for the Slide Hammer being used, drill a hole on each side of the crankshaft rear seal as shown. Drill the holes to a depth of 8.76 mm (0.344 in) to capture the metal case of the crankshaft rear seal as well as the wear ring. 6.

NOTE: Apply a bead of threadlock around the circumference of the outer rear edge of the secondary crankshaft flange.
