Bellows Seal Replacement
1. Clean excess material from the bellows seal (140)
and nozzle guard (80).
2. Remove the nozzle guard (80).
3. Remove the nozzle (15).
4. Lift the bellows seal (140) and pull it over the
threads on the fluid tube (13).
5. Inspect the surface of the tube bearing. If there are
any signs of material contamination, replace the
tube bearing and increase the frequency of the seal
replacement.
The new orbiter coupler bearing may require a
short break-in period before startup. Run the swirl
applicator for 15 minutes at 6600 rpm (no dispens-
ing required). This will ensure the orbiter reaches
normal operation status sooner.
