(6)
Do the steps (4) and (5) two more times.
(7)
TORQUE the nut (18) to 13 m.daN (95.87 lbf.ft) as follows:
(a)
Use the formula to tighten with a torque wrench and adaptor to get the calculated torque figure (Ref. TASK 20-21-11-911-001).
(b)
Set the torque wrench to the calculated torque figure.
(c)
Install the torque wrench on the SPANNER - MLG REAR PIN. NOTE : The axis of the SPANNER - MLG REAR PIN and the torque
____ wrench will make a straight line away from the nut (18).
(d) TORQUE the nut (18). Subtask 32-11-11-220-050-A
G. Dimensional Check
(1) Use a feeler gage to measure the dimensions F as follows: NOTE : It is possible to have zero clearance at one or two of the F1,
____
F2 and F3 points. This is satisfactory.
(a)
For in-service components, the total of the three dimensions (F1
+ F2 + F3) must be equal to or less than 0.5 mm (0.0196 in.).
(b)
For repaired or overhauled components, the total of the three dimensions (F1 + F2 + F3) must be equal to or less than 0.26 mm (0.0102 in.).
(c)
The total of the two dimensions (F4 + F1) must be between 0.37 mm (0.0145 in.) and 1.19 mm (0.0468 in.).

(1)
Align the key slot of the lock-washer (17) with the chamfered slot on the nut (18) and install the lock-washer (17).
(2)
Align the wire (16) with the key slot of the lock-washer (17) and the chamfered slot of the nut (18). Install the wire (16) (in a counterclockwise direction) until the end of the wire (16) engages in the key slot of the locking washer (17).
(3)
Do the bonding (Ref. TASK 20-28-00-912-004).
(4)
Apply SEALANTS (Material No. 09-018) to the wire (16), the lock ring
(17) and the nut (18).
NOTE : You must apply the sealant after you assemble the components
____
over the external surfaces only.
(5) Install the half-seals (24) and (25) as follows:
(Ref. Fig. 407A/TASK 32-11-11-991-009-A)
(a)
Put one half of the forward half-seal (24) in position on the top of the pintle pin (19). Make a knot in a piece of plastic string and put around the groove of the half-seal (24). Pull carefully on the two ends of the string. This will engage the half-seal
(24) between the spherical bearing of the MLG rear pintle and the bush of the rear pintle mounting.
(b)
Pull carefully on one end of the string and use the knot to turn the half-seal (24) through 180 deg. This will put the half-seal
(24) at the bottom of the pintle pin (19). Remove the plastic string.

(c) Put the other half of the forward half-seal (24) in position on the top of the pintle pin (19). Use the plastic string to engage the other half of the half-seal (24) correctly in position. Remove the plastic string.
(d) Put a piece of MISCELLANEOUS (Material No. 19-010) around the half-seal (24) and twist the ends together to retain the half-seals (24) in position.
(e) Do the procedure again to install the aft half-seals (25).
(6) Install the new O-rings (22) on the lubrication fitting (20).
R (7) Carefully install the lubrication fitting (20) in the rear pintle pin (19).
R (8) Install the bolt (21).
WARNING : WEAR GOGGLES WHEN YOU REMOVE OR INSTALL THE LOCKWIRE. CUT,_______ REMOVE AND DISCARD THE LOCKWIRE AS YOU DO THE TASK. LOOSE LOCKWIRE CAN CUT OR BLIND YOU.
R (9) Safety the bolt (21) with MISCELLANEOUS (Material No. 19-010).
R R R R (10) Apply SEALANTS (Material No. 09-018) to: - the shoulder of the rear pintle pin (19) - the outer edge of the lubrication fitting (20) - the bolt (21) but not the threads.
(11) Install the torque shaft 6208CM (6258CM) (Ref. TASK 27-54-45-400-004).
