B. Installation of the MLG Actuating Cylinder
(1) Apply a thin layer of SEALANTS (Material No. 09-016) to the interfaces of:
-
the pin (27) with the cap (32)
-
the washer (33) with the cap (32)
-
the nut (34) with the washer (33)
-
the bolt (29) with the nut (34).
NOTE : Do not apply sealant to the interfaces of:
____
-
the pin (27) and the MLG leg lugs
-
the cap (32) and the MLG leg lugs.
(2)
Install the cap (32), the bolt (29), the washer (33) and the nut (34).
(3)
TORQUE the nut (34) to between 2.4 and 3.0 m.daN (17.69 and 22.12 lbf.ft).
(4)
Safety the nut (34) with the new cotter pin (35).
(5)
Align the fork end (46) with the actuator mounting bracket (44). Make sure that the anti-roll pegs (42) are at the top.
(6)
Install a washer (43) on each side of the actuator mounting bracket (44).
(7)
Use the GUIDE CONE (98D32104015000) to install the pin (20).
(8)
Apply a thin layer of SEALANTS (Material No. 09-016) to the interfaces of:
-
the bottom end of the pin (20)
-
the collar (36)
-
the bolt (41)
-
the washer (39)
-
the nylon-washer (40)
-
the nut (38).
(9)
Put the collar (36) on the pin (20) and install it with:
-
the bolt (41)
-
the nylon-washer (40)
-
the washer (39)
-
the nut (38).

C. Dimensional Check
(1)
Make sure that the dimensions Y1 and Y2 are more than zero at the anti-roll pegs (25). Dimensions Y1 and Y2 are the clearance when the opposite anti-roll peg is held against the washer (30).
(2)
Make sure that the dimension X is between 1.8 mm (0.0708 in.) and 6.1 mm (0.2401 in.), at one of the anti-roll pegs (42). Dimension X is the clearance when the opposite anti-roll peg is held against the washer (43).
NOTE : If the dimensions Y1, Y2 or X are not in the given tolerances,
____ refer to (Ref. CMM 32-31-47) or (Ref. CMM 32-31-86) for fits and clearances of the applicable components.
