) and (refer to figure
1.Ensure that the left spoilers are closed.
2.Fit on the left spoilers trailing edge the backlash (AGE
NO. 00009) test equipments and set the comparator
(AGE NO. 00062) to zero.
NOTE
The comparator (AGE NO. 00062) must be
no more zeroed until the test is terminated.
3.Use the hydraulic test stand (AGE NO. 00262), supply
No. 1 and No. 2 hydraulic systems at 3000 psi (210
kg/cm
²
).
4.Apply, by the dynamometer (AGE NO. 00034), on the
left spoilers trailing edge, a vertical load and measure
the left spoilers displacement as follows:
A.Gradually apply a load upwards up to 22.48 lb
(10.20 kg) maximum, leaving out the reading on
the comparator (AGE NO. 00062).
B.Stepwise unload, every 4.50 lb (2.04 kg), up to
zero load and simultaneously read, on the
comparator (AGE NO. 00062), the related
displacement value of the left spoilers.
C.Stepwise load downwards, every 2.25 lb (1.02 kg),
up to 11.24 lb (5.10 kg) maximum and
simultaneously read, on the comparator (AGE NO.
00062), the related displacement value of the left
spoilers.
D.Stepwise unload, every 2.25 lb (1.02 kg), up to
zero load and simultaneously read, on the
comparator (AGE NO. 00062), the related
displacement value of the left spoilers.
