ABSTRACT:
The cleaning system includes a plurality of generally dovetail-shaped slot blocks having a slot along a radial inner side, an abrasive media or belt and a backing tube. Upon insertion of the blocks into the dovetail slots of a rotor wheel and aligning the block slots with the cooling slot, the abrasive media and backing tube are inserted in the cooling slot tunnel. The abrasive media may extend through end feeder blocks. With the backing tube applying pressure radially outwardly against the abrasive media, back and forth motion applied manually from outboard of the rim of the rotor cleans the surfaces of the cooling slot without disassembly of the rotor.
