Revision G Page 53 of 102 P/N 1004646 Doc. No. W7001-24-01
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
4.3 Step 30).
