Center Wing Stop and Outside Wing Stop Assembly
U-bolt the center wing stop (1) to the
second bar from the rear on the center frame as
shown in Figure 12. Use 5/8 x 4 x 4 1/4 u-
bolts (2) with lock washers and hex nuts.
Center the wing stop from side to side. Insert
the 1/2 x 4 1/2 transport lock quick pins (3) in
the holders on the wing stop.
On models 6541-6548, attach the
center wheel alignment stub (4) to the center
of the wing stop using 5/8 x 2 1/2 x 3 1/2 u-
bolts (5), lock washers and hex nuts. U-bolt
the wing wheel alignment stub (6) to the inside
wing frame using 1/2 x 3 x 5 u-bolts (7), lock
washers and hex nuts. See shank layout for
proper location for your model.
On 5-section models, U-bolt the wing
lock mount (8) on the inside wing with 1/2 x 3
x 5 u-bolts (9). U-bolt the wing lock “T”
bracket (13) on the outside wing with the same
1/2 x 3 x 5 u-bolt (9). Refer to the shank layout
for your particular model for the exact location
of the wing lock mount and lock “T” bracket.
Use lock washers and hex nuts on these u-bolts
(Note: On models 6537 and 6541 the T-
Bracket uses 5/8 x 4 x 4 1/4 u-bolts). Bolt the
wing latch (10) to the wing lock mount (8)
with a 3/4 x 4 1/2 bolt (11). Slide a 3/4 flat
washer (12) between the latch and the mount
on each side to take out the slop. Use a 3/4”
lock nut but do not torque down. The latch
must move freely.
Insert the rear stand leg (14) into the
frame mount bracket (15) and pin together
with 3/4 x 4 1/2 pin (16). U-bolt the whole
assembly to the rear bar of the center frame
with two 5/8 x 4 x 4 1/4 u-bolts (17) with lock
washers and hex nuts.
