Abstract
Combustor maintenance assemblies, tools and methods for manipulating cross-fire tubes in combustor assemblies are provided. A tool includes a base and an arm pivotally connected to the base. The arm includes an effort portion and a load portion, the load portion extendable into a passage defined by the compressor discharge casing. The tool further includes a contact member extending from the load portion to contact the cross-fire tube. The contact member includes a head end for contacting a second end of the cross-fire tube, and a joint disposed between the head end and the load portion, the joint allowing movement of the head end relative to the load portion. The arm is movable such that the contact member contacts the cross-fire tube and applies a force to the cross-fire tube generally along a longitudinal axis of the cross-fire tube.
