This is page AT-40 of a Nissan factory service manual, from the Automatic Transaxle (AT) section under "Repair for Component Parts – Final Drive (Cont'd)". It covers the ASSEMBLY procedure for the final drive differential. The eight-step procedure instructs the technician to: install the side gear and thrust washer in the differential case; install the pinion mate gear and thrust washer while rotating them; insert the pinion mate shaft (taking care not to damage the pinion mate washers); measure the clearance between the side gear and pinion mate gear per the Inspection section, adjusting if necessary; install the pinion mate shaft lock pin with a punch, ensuring the lock pin is flush with the case; install the speedometer worm and stopper; press on the differential side bearing inner races; and apply locking sealer to the final gear bolts before installing the final gear. A key specification is given: side gear to pinion mate clearance of 0 – 0.3 mm (0 – 0.012 in); side gear thrust washer selection is referenced to S.D.S. Four illustrations (figure codes SAT701, SMT840, SMT618, SMT620) show gear installation, shaft insertion, lock pin installation, and final gear bolt tightening.
