2-47.6 MEASUREMENT OF INNER TABS
CONVENTIONAL PLAY (refer to figure
) (Cont'd)
D.Stepwise unload, every 5 N, up to zero load and
simultaneously read, on the comparator, the
related displacement value of the left balance tab.
E.Stepwise load upwards, every 5 N, up to 30 N
maximum and simultaneously read, on the
comparator, the related displacement value of the
left balance tab.
8.Put the values obtained in a diagram and draw a
graph, load applied Vs left balance tab displacement.
9.To calculate correctly the backlash (refer to figure
diagram load applied vs surface displacement has
been drawn:
A.Draw the tangent to the highest point of the
unloading curves (U1 and U2) and of the loading
curves (L1 and L2) up to the intersection with the
surface displacement axis.
B.The backlash value C1 is the distance between the
intersection of the lines U1 and L2 read on the
surface displacement axis.
C.The backlash value C2 is the distance between the
intersection of the lines U2 and L1 read on the
surface displacement axis.
D.The total resulting backlash C is defined as the
mean value between C1 and C2.
10.Check, from the graph, that the backlash C is 0.082 in
(2.1 mm).
11.Remove from the LH (RH) balance tab trailing edge
the elevator check template (AGE NO. 00038) and
comparator (AGE NO. 00062).
12.Repeat steps 5 thru 10 for RH balance tab. Results
must be the same.
