11. DEFORM LOCKING CUP (1) INTO TWO OF THE
FOUR CASTELLATIONS OF THE PLAIN ROUND NUT
(2) 180 DEGREES APART USING A BALL PEEN
HAMMER AND BRASS DRIFT
CAUTION
Do not substitute the brass drift for any
tool made from a metal that is harder than
brass. Tool damage to the bevel gear or
compressor shaft is unacceptable and will
result in replacement of the entire forward
module.
a.
Lightly deform locking cup (1) into two cas-
tellations of the plain round nut (2) 180 de-
grees apart by placing the end of the brass
drift against the side of the locking cup (1) and
striking the brass drift lightly with a ball peen
hammer. Deform locking cup (1) enough to
engage the two castellations of the plain
round nut (2) without shearing or cracking the
locking cup (1).
b.
Inspect locking cup (1) for shears or cracks.
No shears or cracks are acceptable. If any
shears or cracks are present, replace locking
cup (1).
c.
Inspect bevel gear (3) and compressor shaft
(4) for tooling marks.
NOTE
LE5579
If tooling marks exist, the forward module
is not repairable at DS level of mainte-
nance. Reassemble forward module with
original hardware and replace forward
module (page 5-13).
