NOTE : If the breakaway torque of the LH (47) or RH FWD nut
____
(48) is less than to 0.1 m.daN (8.84 lbf.in), replace
the nut.
If the breakaway torque of the AFT nut (50) is less
than to 0.2 m.daN (17.69 lbf.in), replace the nut.
3 Turn the nuts (47), (48) and (50) until they are in contact
_ with the APU mount brackets or vibration isolator.
4 TORQUE the LH (47) and the RH (48) nuts to between 2.5 and 3.1
_ m.daN (18.43 and 22.86 lbf.ft)
5 TORQUE the aft nut (50) to between 7.7 and 8.5 m.daN (56.78
_
and 62.68 lbf.ft)
6 Mark the nuts with red locking varnish to identify the torqued
_
position.
(e) Do a visual check of the FWD LH vibration isolator, FWD RH vibration isolator and AFT vibration isolator.
