This maintenance manual is intended to make the repair and maintenance of the FK40 easier for the servicing personnel. The maintenance
manual contains a complete description of each work step for the disassembly and assembly of the compressor components. Each step must
be carefully adhered to in order to ensure a reliable repair.
Note:
For replacing components GEA Bock provides suitable spare part kits. Yet assembly jobs which go beyond the replacement of the shaft
seal, the valve plates and - if there is one - the capacity regulator (accessory) should be checked carefully for their economic efciency
beforehand.
The maintenance manual describes the standard type of the FK40 compressor which we deliver. Because of different system conceptions,
some passages in this service manual may differ from the unit which you have come across. In these cases the present manual should
be used in analogous fashion.
