4.3 ADJUSTING THE GEAR
UP POSITION
1.
DO NOT adjust the rod linkages (Item 3)
when setting the over center up adjustment.
2.
Rotate the actuator rotation arm fully toward
the gear up position.
3.
When the actuators internal piston contacts
the “UP” adjustment setscrew, check to
make sure all the linkages have rotated past
Top Dead Center (TDC) by pushing and
pulling on the Top Arm Assembly. The
“UP” adjustment screw (Item 10) should not
need to be adjusted if properly set using
Wipaire Tool 1004800 during the actuator
maintenance. (If it is found that one can
reverse drive the rotary actuator and pull the
gear down by hand, the rod linkage and the
actuator arms have not moved past TDC.
Re-check the position of the “UP” stop
using Wipaire Tool 1004800. If the “UP”
position is found to be correct, look for signs
of damage in the floats as something is out
of position preventing the stop setting using
Tool 1004800 from being correct. Call
Wipaire’s Customer Service Department for
specific instructions.
4.
Bleed air from hydraulic system by
actuating the gear several times with the
electric hydraulic pumps. See Chapter 5,
Section 5.1, for specific bleeding
instructions.
5.
If it is necessary to adjust gear up and down
position switches proceed to next section. If
not, lower gear and reattach oleo shock strut
to top arm assembly. When aircraft weight
is fully on the wheels, remember to set the
NAS-428 bolt on the Main Gear Down Stop
Assembly (refer to Section 4.2 Step 30).
