SOCKET BOLT
Catalogue part number OSBM1230 for FLUTEK K3V / K5V tandem pumps. Drawing position 401.
OSBM1230 is the FLUTEK catalogue part number for SOCKET BOLT in the K3V140 / K3V180 / K5V160 (27-40 t) tandem pump family. It sits at drawing position 401 in the 400 group. It is a service-replacement item, not an assembly, and is picked against the pump serial rather than the machine alone.
SOCKET BOLT is a K3V140 / K3V180 / K5V160 catalogue line in the DTP table, printed on catalogue page 24. On that page it sits next to position 326 (COVER) and position 406 (SOCKET BOLT), out of 71 numbered lines in the table. One set takes 4. It is a build-specific line, listed for K3V180 only - the other configurations of the family take a different number at the same position.
