All vehicles 1. Remove the transmission. For additional information, refer to Section 307-01 for automatic transmissions or Section 308-03 for manual transmissions. Vehicles with manual transmission 2. Remove the clutch disc and pressure plate. For additional information, refer to Section 308-01. All vehicles IN-VEHICLE REPAIR (Continued) 3. Remove the 10 bolts and flexplate or flywheel. • Discard the bolts. 4. NOTICE: Use extreme care when removing the flywheel front adapter to prevent damage to the alignment dowel pin. 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. Using the 2 drilled holes, the Slide Hammer and a commercially available body dent puller attachment, walk the seal out of the rear cover by alternating from side to side to remove the crankshaft rear seal. • Discard the crankshaft rear seal. Vehicles with an original service seal 7. NOTE: Original equipment seals will not have a wear ring. If a service part has previously been installed, it will have a wear ring. If the service part was a redesigned seal, the wear ring will have been removed with the seal in the previous step. If the service part was an original service seal, the wear ring will remain in the engine after the seal has been removed. If the wear ring remained in the engine after removing the seal, use the Crankshaft Rear Wear Ring Remover to remove and discard the crankshaft rear seal wear ring. All vehicles 8. Clean and inspect the crankshaft sealing surface. Installation Vehicles with an original service seal 1. NOTICE: The crankshaft rear seal and wear ring are a one-piece design and need to be installed as an assembly. Do not separate the wear ring from the crankshaft rear seal or damage to the seal may occur. NOTE: An original service seal will have a wear ring without a flange and pre-applied threadlock. NOTE: Apply a bead of threadlock around the circumference of the outer rear edge of the secondary crankshaft flange.
