(11)
Make sure that the radius washers (28) are installed correctly against the internal contour of the pintle pin (27).
(12)
TORQUE the nuts (33) to 0.50 m.daN (44.24 lbf.in).
(13)
Make sure that the radius washers (28) have not moved.
(14)
Safety the nuts (33) with new cotter pins (34). If the holes for the cotter pins do not align, tighten the nuts (33) sufficiently to align the holes.
(15)
Apply SEALANTS (Material No. 09-016) to the lockbolts (29), the spacers (32), the nylon washers (31), the laminated shims (30), the nuts (33) and the cotter pins (34).
NOTE : Apply the sealant after you assemble the components, over the
____
external surfaces only.
(16) Apply a layer of STRUCTURE PAINTS (Material No. 16-021) or STRUCTURE PAINTS (Material No. 16-016) on all the sealant.

(1)
Apply SPECIAL MATERIALS (Material No. 05-047) to the threads of:
-
the nut (18)
-
the rear pintle pin (20).
(2)
Install the washer (19) on the rear pintle pin (20).
(3)
Install the nut (18) on the rear pintle pin (20).
(4)
Make sure that the shoulder face below the head of the pintle pin
(20) touches the forward bush face, so that there is no clearance at F1.
NOTE : As the anti-rotation washer (24) is thinner than the bush
____ flange, there will be a clearance between it and the rear pintle pin (20).
(5) TORQUE the nut (18) to 20 m.daN (147.49 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 PINTLE
(98D32104005000).
NOTE : The axis of the SPANNER-MLG REAR PINTLE and the torque
____ wrench will make a straight line away from the nut (18).
(d) TORQUE the nut (18).
(6)
Loosen the nut (18).
(7)
Do the steps (5) and (6) two more times.
(8)
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 PINTLE. NOTE : The axis of the SPANNER-MLG REAR PINTLE and the torque
____ wrench will make a straight line away from the nut (18).

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 0.25 mm (0.0098 in.).
(c)
The total of the two dimensions (F4 + F1) must be between 0.575 mm (0.0226 in.) and 1.17 mm (0.0460 in.).
