SERVICE MANUAL & I.C.A. FOR THE 7000 AMPHIBIOUS FLOATS
Revision G Page 49 of 102 P/N 1004646 Doc. No. W7001-24-01
8.
NOTE: The actuator should not need
adjustment while in service. The only time
adjustment should be necessary is when the
actuator is disassembled in order to replace
internal seals. Assuming this has been done
the remaining steps are for re-rigging the
actuator to be installed back in the float.
9.
With the actuator assembled and removed
from float, attach Wipaire Tool 1004800 to
the actuator, taking note that the
FORWARD arrow is pointing forward on
the actuator. Use the 5/16-18 bolts to
attach the tool to the actuator.
10.
Rotate the actuator shaft fully to the DOWN
position. If the two keyway slots do not line
up when the actuators internal piston
contacts the “DOWN” adjustment set screw
(Item 8), the actuator needs adjustment. It
may be necessary to use one of the actuator
arms removed in step 5 to help rotate the
actuator.
11.
To adjust the “DOWN” position,
loosen the “DOWN” adjustment screw
jamb nut (Item 9) and back off the
adjustment screw.
12.
Align the keyway on the actuator shaft
(Item 4) with the keyway on Wipaire
Tool 1004800. Insert the parallel key
removed in step 5 into the aligned
keyways.
13.
Thread in the Down Adjustment
setscrew until light contact is made
between the setscrew and the actuators
internal piston.
Do not over tighten as the actuator cannot
rotate with Wipaire Tool 1004800 and the
key installed. Over tightening can
damage the face of the actuator piston.
14.
With setscrew positioned against the piston
face, tighten the adjustment screw jamb
nut (Item 9).
15.
Repeat steps 10 - 14 for setting the
UP position setscrew.
(See figure 4-5)
16.
Install actuator in float by reversing
steps thru 7. Safety wire 5/16-18 bolts
when installed. Outer face of actuator
arms should be flush to actuator shaft.
It is recommended to leave the spring
disconnected during gear rigging.
