8.
Position three segments (1, 9, and 19) so that
flanges (15 and 16) of segments (1 and 9) point
straight up. Install enough shims (14) between
flanges to give a snug fit of three segments
against mounting flange (2).
NOTE
About five shims are needed for snug
fit.
9.
Move three segments (1, 9, and 19) forward just
enough to uncover four mounting holes (6) in
mounting flange (2). Make sure flanges (15 and
16) point straight up. Mark centerline (22) of four
holes on segments (1 and 9) with pencil (E271).
10.
Release four fasteners (21). Remove three
segments (1, 9, and 19).
11.
Measure 0.440 inch in from edge of two top
sections (1 and 9) at each pencil mark (22). Drill
one 0.220 inch hole at that point on each mark.
12.
Position three segments (1, 9, and 19) around
mounting flange (2). Fasten bottom segment
(19) to two top segments (1 and 9) with four
fasteners (21).
13.
Check that seals (3, 10, and 20) at forward end of
three segments (1, 9, and 19) fit against shroud
(4) and do not overlap. Trim seals as needed.
Gap between seals shall not exceed 0.06 inch.
