Abstract
A system and method for cleaning receiver slots with hook-fits for stator blade ring segments. A first cleaning tool with an abrasive coating and sideward projection in the shape of the hook is slid through the slot using the hook-fit as a guide. A second cleaning tool with an abrasive coating and a formed/machined hook-fit used as a guide while cleaning the receiver slots as it is pushed through the receiver slots. The tools remove trash, oil rust/oxidation, and other foreign materials from receiving slot. Both tools may attach to a metal rod with two knuckles as part of the handle that connects to and uses the hook-fit as a guide enabling the operator to reach deep into the radius of the compressor case receiver slots and hook-fits located adjacent to and beneath the rotor and rotor blades so that the hook-fit and receiver slot can be thoroughly cleaned.
