A 737-300/400/500MAINTENANCE MANUAL
(e) With full RIGHT WING DOWN trim input, do a check of the control
wheel movement:
1) Manually turn the captain's control wheel to 105 degrees
clockwise.
2) Turn the captain's control wheel back to the neutral
position.
3) Turn the captain's control wheel counterclockwise to 75
degrees.
a) Make sure the captain's control wheel moves freely.
(f) With full RIGHT WING DOWN trim input, do a check of the
electric aileron trim actuator in the main gear wheel well:
1) Make sure the aileron trim actuator does not touch the
retaining pin of the aileron centering spring when you turn
the control wheel counterclockwise.
2) Measure the force necessary to hold the control wheel at
the 75 degrees position.
a) Make sure that the force is not more than 21 pounds at
6.5 inches radius or 137 pound-inches torque.
3) Release the control wheel.
a) Make sure that the control wheel goes back to 60 |3
degrees (10 |1/2 trim indicator units) clockwise.
NOTE: If it is necessary, apply a light finger____
pressure to the control wheel while trimming the
aileron to achieve the required 10 units
deflection of control wheel. The light manual
help for the control wheel to turn is to
overcome possible friction in the input side of
the control system which can be slightly greater
than the force of the centering springs to hold
the centering roller into the cam detent.
(g) Operate the two aileron trim switches to put the aileron
control wheels back to the neutral position.
(h) Operate one aileron trim switch in the LEFT WING DOWN
direction.
(i) Operate the same aileron trim switch in the RIGHT WING DOWN
direction.
1) Make sure the control wheels do not move.
(j) Operate the other aileron trim switch in the LEFT WING DOWN
direction.
(k) Operate this same aileron trim switch in RIGHT WING DOWN
direction.
1) Make sure the control wheels do not move.
