Scope of work:

We performed an inspection and repair on a gearbox LOHMANN & STOLTERFOHT GAA-400-SN.


We got this LOHMANN & STOLTERFOHT GAA-400-SN in our gearbox workshop in October 2016 from Netherlands client. After the repair we did a test run, we transported the gearbox back to the client.

Work carried out:

- Overhaul of the jetpump gearbox PS
- Solve leakage of output shaft
- Exchange of Spiroflex-elements PS and SB
- Disassembly of Pneumaflex SB and PS

- Renew the output coupling
- After 100 operating hours the bolts torque need to be checked (Spiroflex)
- The Spiroflex-Elements that were stored on board were bended, because of wrong storage. The storage has to be carried out flat on the companion flange or on the hub, for more information ask Siemens
