Never reuse locking hardware. Reuse of locking hardware such as lockwashers,
locking nuts, cotter pins, and lock wire can result in undetected loosening of
fastening hardware causing catastrophic component failure resulting in death,
injury, or damage to equipment. In accordance with TB 43-0218, ensure that all
locking hardware is discarded upon removal and replaced with new.

1. Use a wrench to loosen the discharge nozzle (figure 1, item 1).
2. Remove the discharge nozzle (figure 1, item 1) from the pipe fitting (figure 1, item 2).
