REPAIR OR REPLACEMENT - Continued
(15) Install cylinder depth gage (Figure 19, Item 90) in injector tube. Using profile gage
(Figure 19, Item 91), pre-measure distance from fire deck to gage (final reading will have to be
within +/- 0.014 inch (0.36 mm) of fire deck).
(16)
Wash interior of injector tube (Figure 19, Item 84) to prepare for second reaming operation.
(17) Apply a few drops of cutting oil on bevel seat of injector tube (Figure 19, Item 84). Lower bevel
reamer (Figure 19, Item 92) carefully into injector tube until it contacts bevel seat.
(18) For trial cut, turn bevel reamer (Figure 19, Item 92) steadily without applying any downward
force. Remove reamer, clean out chips, and observe what portion of injector nut seat was cut.
(19) Proceed with reaming and withdraw bevel reamer occasionally to observe progress.
(20) Continue reaming until shoulder of spray tip is within +/- 0.014 inch (0.36 mm) of fire deck. Use
gages (Figure 19, Items 91 and 90) to measure distance.
(21) Wash interior of injector tube (Figure 19, Item 84).
