Nissan High-Reverse Clutch (Front) Disassembly & Inspection - AT-29 Exploded View

This is page AT-29 from a factory automatic transmission service manual section titled 'Repair for Component Parts,' covering the High-reverse Clutch (Front). The page begins with an exploded parts diagram (figure SAT310) labeling all components of the clutch assembly: retainer plate, driven plate, spring retainer, piston seal, drive plate, waving snap ring, snap ring, spring, piston, and the high-reverse clutch (front) drum. Under DISASSEMBLY, the instructions direct the technician to compress the clutch springs using special tool ST25420001 (J26063-A) and remove the snap ring from the spring retainer (figure SAT313), and to use an air gun with a tapered rubber tip to apply air pressure and loosen the piston from the drum (figure SAT315). The INSPECTION AND ASSEMBLY section specifies checking the clutch drive plate facing for wear or damage — drive plate thickness must not be less than 1.6 mm (0.063 in), with a standard thickness of 1.70–1.85 mm (0.0669–0.0728 in) — and inspecting for snap ring wear, weak or broken coil springs, and a warped spring retainer. Readers can learn the clutch pack component layout, disassembly technique, required special tool number, and wear-limit specifications.
