NOTE : To find the correct TORQUE value when spanner wrenches are
____ used refer to the formula in standard practices (Ref. TASK 20-21-11-911-001).
(a) Install the spanner nut (75) on the pin (15).
(7) TORQUE the spanner nut (75) to 80 lbf.ft (10.84 m.daN) minimum. Use WRENCH SET - AFT ENGINE MOUNT (RSE1098-5) to adapt torque wrench to the spanner nut.
(8) Install the spanner nut (65) on the bolt (10).
(9) TORQUE the spanner nut (65) to 35 lbf.ft (4.74 m.daN) minimum. Use WRENCH SET - AFT ENGINE MOUNT (RSE1098-1) to adapt the torque wrench to the spanner nut.
(10) Put the retainers (70) and (60) against the bracket (40) to make sure the bolt holes are aligned.
(11) If the holes are not aligned, increase the torque on the spanner nuts
(65) and (75) to align the holes.
NOTE : Do not torque the nut (75) more than to 95 lbf.ft (12.88
____ m.daN) or the nut (65) more than to 42 lbf.ft (5.69 m.daN)
(12) If the holes are aligned, install the bolts (30), the washers (35) , (50), and the nuts (55).
NOTE : Make sure that you put the countersunk washers under the bolt
____
heads.
(13) TORQUE nuts (55) to between 24 and 27 lbf.in (0.27 and 0.30 m.daN).
(14) Install the retaining pin (5) through the pin (15).
