x 8-1/4 Pin and 1-1/4 x 10-7/8 Pin. Set aside.
3. Place the Outer Hinge Link End with the bushing
between the Center Frame Hinge Plates. See
Figure 2-47. Slide a 1-1/4 x 2-1/2 x 12ga Thrust
Washer between the Outer Hinge Link and the Center
Frame Hinge Plates. Insert 1-1/4 x 10-7/8 Pin into the
side of the Center Frame Hinge Plate with the Keeper
Plate so the Roll Pin fits into the slot. See
Figure 2-44. Place two Flat Washers on the end of
the Pin. Secure with 5/16 x 2 Roll Pin.
4. Place the Inner Hinge Link End with the bushing
between the Wing Hinge Frame Plates. Slide a 1-1/4

Hinge Link and the Wing Frame Hinge Plates. Insert
1-1/4 x 8-1/4 Pin into the side of the Wing Hinge Plate
with the Keeper Plate so the Roll Pin fits into the slot.
See Figure 2-44. Place two Flat Washers on the end
of the Pin. Secure with 5/16 x 2 Roll Pin.
5. Swing the Inner and Outer Hinge Links together along
with the Hydraulic Cylinder Rod End Clevis. Place a
1-1/4 x 2-1/2 x 12ga Thrust Washer between each
