Outside Wing Assembly
On 5-section models, assemble the
outside wing (1) by attaching the outside hinges
(2) to the wing with 1 x 6 hex bolt (3) and 5/8 x
3 x 5½ u-bolts (4) as shown in Figure 4. Use a
nylon lock nut on the 1 x 6 hex bolt (3) with
lock washers and hex nuts on the u-bolt.
Attach the 180 degree rocker (5), bulge side
out, with the 1 x 3 3/8 usable headed pin (6), 1”
machine washer and 3/16 x 2 cotter pin.
Attach the outside wheel bracket (7) just
as we did the inside ones, using the 1¼ x 6
pins (8) and 3/8 x 2¼ GR 8 hex bolts & lock
nuts. Slide the walking beam assembly (9) into
the wheel bracket sleeve as shown in Figure 4.
Again, it is recommended to use some form of
anti-seize product on the spindle. Secure with
5/16 x 3 clevis pin (10) and 1/8 x 1” cotter pin.
Note that the longer 14” long spindle assembly
(or 14 ½” with heavy hub option) goes to the
front. Bolt on the 9.5L x 15 tire and wheels
(11) with the ½ x 1¼ lug bolts (12) or ½” lug
nuts with the heavy hubs.
Models 6536 & 6542 use one tire and a
14 1/2” Hub & Spindle assembly (13) as shown
in insert.
