9-3. DIFFERENTIAL OUTPUT SHAFT SEAL REPLACEMENT INITIAL SETUP: Tools ____ General mechanic's tool kit: automotive (Appendix G, Item 1) Special Tools __________ Axle shaft and seal installer (Appendix G, Item 79) Materials/Parts _____________ Seal washer (Appendix E, Item 198) Locknut (Appendix E, Item 46) Sealing compound (Appendix B, Item 50) Manual References _______________ TM 9-2320-280-24P Equipment Condition _________________ Service brake rotors removed (TM 9-2320-280-20). Maintenance Level _______________ Direct support This task covers: a. Removal b. Installation NOTE New configuration side mounting bracket allows for output shaft seal replacement without bracket removal. Inspect bracket to determine output shaft seal clearance. If clearance exists, perform steps 2 through 4. If clearance does not exist, perform steps 1 through 4. 1. Remove old configuration side mounting bracket (9) (para. 12-16). 2. Remove locknut (5), seal washer (4), and output flange (3) from output shaft (2). Discard seal washer (4), and locknut (5). 3. Remove two capscrews (7) and brake adapter (6) from differential (1). 4. Remove output shaft seal (8) from differential (1). NOTE New configuration side mounting bracket allows for output shaft seal replace-ment without bracket removal. If side mounting bracket was not removed, perform steps 2 through 4. If bracket was removed, perform steps 1 through 4. 1. Install new configuration side mounting bracket (9) (para. 12-16). 2. Using axle shaft and seal installer, install output shaft seal (8) in differential (1). CAUTION Apply a liberal amount of thread sealing compound to the tapped holes of differential. To allow adequate coating of threads, install capscrews shortly after applying thread sealing compound. Failure to do this could allow capscrews to loosen and cause damage to differential. 3. Apply sealing compound to tapped holes of differential (1) and install brake adapter (6) on differential (1) with two capscrews (7). Tighten capscrews (7) to 110-140 lb-ft (149-190 N •m). 4. Install output flange (3), seal washer (4), and locknut (5) on output shaft (2). Tighten locknut (5) to 170 lb-ft (231 N•m). b. Installation a. Removal TM 9-2320-280-34 9-2 Change 1
