Nissan AT Final Drive Disassembly & Side Gear Clearance Spec (AT-39)

This is page AT-39 from a Nissan service manual, covering the 'Repair for Component Parts – Final Drive' section within the Automatic Transaxle (AT) chapter. It details disassembly and inspection procedures for the final drive/differential assembly. Disassembly steps include removing the final gear, driving out the pinion mate shaft lock pin and withdrawing the pinion mate shaft, and driving out the differential side bearing inner races, with a caution not to confuse the right- and left-hand bearings. The inspection section instructs checking the mating surfaces of the differential case, side gears, and pinion mate gears (replacing as required), and measuring the clearance between the side gear and pinion mate gear. This measurement uses special tool KV38105900 (J33201) with a dial gauge set on the side gear; the side gear is moved up and down to read gauge deflection, and both side gears must be measured. The specified side gear to pinion mate clearance is 0–0.3 mm (0–0.012 in). Illustrations are referenced by figure codes SMT610, SMT611, SMT838, SMT615, and SMT616. The page provides the specification and tool reference needed to service the transaxle differential.
