2-31 REMOVE COMPRESSOR ROTOR BLADES (Continued)
Number of blades and stages in which
they were replaced must be entered in
engine record. Maximum of 50 blades
may be replaced on compressor rotor
between overhaul cycles.
First, second and third stage blades are
removed forward. Removal of first
stage blade is shown in step 1.
When removing compressor blades, be
certain that blade, pieces of Iockpin,
and spring do not fall into lower com-
pressor housing. These items could
cause compressor rotor malfunction.
If these items do fall into lower com-
pressor housing, they must be removed.
1. Remove first stage blade (1) from disc as
a. Align forward blade root (2) with slot (3)
in bearing housing.
