Abstract
A tool for decoupling a telescoping tube from a first liner of a gas turbine engine is disclosed. The tool includes a rod partially positioned in a telescoping tube passage. The rod includes a first portion having a non-circular cross-section and a threaded second portion positioned in a second combustion chamber. A plug couples to the rod and engages a first side surface of the telescoping tube. A base defining a base passage extending therethrough is positioned in a second combustion chamber. The base passage includes a first portion having a non-circular cross-section. The first portion of the rod is at least partially positioned in the first portion of the base passage. A handle threadingly couples to the rod. Rotating the handle in a first direction moves the handle along the rod toward the first combustor to decouple the telescoping tube from the first liner.
