Nissan Automatic Transmission Brake Band & Band Servo Exploded Diagram (AT-34)
Service manual page AT-34 showing an exploded brake band and band servo assembly with inspection notes.
This is page AT-34 from a factory-style automatic transmission service manual section titled 'Repair for Component Parts — Brake Band and Band Servo.' The top of the page presents an exploded parts diagram (figure SAT460) of the brake band and band servo assembly, labeling components including the snap ring, servo piston retainer, O-ring (marked 'Always replace'), return spring, band servo piston stem, brake band, band servo piston, band servo thrust washer, anchor end pin, washer, and adjust brake band (adjusting nut/pin area). The lower half of the page covers INSPECTION procedures: it instructs the technician to inspect the band friction material for wear and to replace the band if cracked, chipped, or burnt spots are apparent, accompanied by an illustration (SAT327) of a hand holding the brake band for inspection. A second bullet instructs checking the band servo components for wear and scoring. The page carries the AT (Automatic Transmission) section numbering. No torque values, part numbers, or specific vehicle year/model applicability appear on this page; it serves as a disassembly reference and inspection guide for the band servo of an automatic transmission.
