C. Removal of the Damper Assemblies
(Ref. Figure 404)
NOTE: This task is typical for the left or right
damper assembly.
Jacking
(1). If necessary, jack the rotorcraft until
skid tubes (3, 4) clear the ground (ref.
Section 07-10-00).
(2). Remove sealant from heads of bolts (14,
18, 20).
(3). Remove bolts (14), countersunk
washers (13), flat washers (15), and
nuts (16).
(4). Remove lockwire from bolts (18).
(5). Remove bolts (18) and washers (17).
(6). Remove bolts (20) and washers (19).
(7). Remove damper assembly (2).
D. Installation of the Damper Assemblies
(Ref. Figure 404)
NOTE: This task is typical for the left or right
damper assembly.
Consumable Materials
(Ref. CSP−SPM)
Item Nomenclature
C211 Sealing Compound, Corrosion Inhibitive
C702 Lockwire
(1). Align the bolt holes of damper assembly
(2) and aft crosstube (1).
(2). Install countersunk washers (13), bolts
(14), flat washers (15), and nuts (16).
(3). Install countersunk washers (17) and
bolts (18).
(a). Torque bolts (18) 100 to 140 in-lb
(11.30 to 15.82 Nm).
(b). Safety bolts (18) with lockwire
(C702).
(4). Attach damper assembly (2) to skid
tube assembly (3 or 4) with washers
(19) and bolts (20).
(5). Apply masking tape to drain ports of
damper assembly (2).
Sealing Compound (C211)
Do not put sealing compound
(C211) in the drain ports of
damper assemblies (2). Blocked drain ports
can cause internal corrosion in damper as
semblies (2).
(6). Environmentally seal all external
mating parts with sealing compound
(C211) (ref. CSP-SPM, Section
20-50-00).
(7). Remove masking tape.
(8). Lower the rotorcraft (ref. Section
07-10-00).
E. Removal of the Skid Tube Assemblies
(Ref. Figure 404)
NOTE: This task is typical for the LH or RH
skid tube assemblies.
Jacking
(1). Jack the rotorcraft until damper
assemblies (2) are fully extended (ref.
Section 07-10-00).
(2). Remove sealing compound (C211) from
heads of bolts (12, 20).
(3). Remove bolts (12) and washers (11)
from forward fitting spacer (6) and skid
tube (3 or 4).
(4). Remove bolts (20) and washers (19)
from dampers (2) and skid tube (3 or 4).
