The present application provides an aft plate removal tool for servicing a combustor. The combustor includes an end cover, an aft plate downstream of the end cover, and a number of tubes extending through the aft plate. The aft plate removal tool includes a base plate and a threaded rod. The base plate is attached to the end cover. Rotation of the threaded rod advances the threaded rod against the aft plate until the threaded rod pushes the aft plate off of the tubes.

Aft inner cap plate removal method and tooling for a combustor with micromixer tubes

The present application provides an aft plate removal tool for servicing a combustor. The combustor includes an aft plate with a central passage and a number of tubes extending through the aft plate. The aft plate removal tool includes a central screw, a lower housing attached to the central screw, the lower housing including a number of spring loaded lower housing feet, and an upper housing attached to the center screw, the upper housing including a number of spring loaded upper housing feet. The aft plate removal tool is inserted through the central passage of the aft plate such that rotation of the upper housing advances the spring loaded upper housing feet against the aft plate until the spring loaded upper housing feet push the aft plate off of the tubes.

A method of repairing a fuel injector including a plurality of pre-mix tubes that each extend from a fuel plenum to an outlet portion includes removing the outlet portion from at least one pre-mix tube to define an exposed end portion, machining an inner surface of the at least one pre-mix tube at the exposed end portion to form an increased inner diameter relative to an inner diameter of the pre-mix tube upstream from the exposed end portion, and coupling a tube tip to the exposed end portion.
