Maintenance
11. Check total travel of rotating assembly. This will remain constant within 0.039 in (1 mm). If
large variation occurs disassemble and diagnose. Something is not seated properly.
12. Install impeller locating ring (361H) and impeller key (178). Apply high vacuum grease to
both locating ring and key or super glue them in place so they don’t fall out when
assembling the impeller.
CAUTION:
Burn hazard. The impeller will get hot. Wear insulated gloves when handling the impeller.
NOTICE:
Allow the shaft and intermediate cover to cool to ambient temperature before proceeding
with disassembly.
13. Assemble impeller (101A-101L) onto the shaft (122) from the thrust end. The impeller is an
interference fit. Use an electric induction heater to heat the impeller to 300°F-400°F
(150°C-200°C). Apply an anti-seize compound to the outer diameter of the impeller rings.
