摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to servicing and repair of automotive ICE. To remove dist from thread turns, device with through hole and opposed grooves on side surface is screwed in threaded bore. Taper id drilled on device bottom end face. Device thread pitch should equal that of dead bore. Device material features lower hardness that that of part with dead threaded bore. Device should be screwed in bore against the stop.
