the previously assembled truss and connect to
the torque tube using two 1 x 3 3/8 usable
clevis pins (5), 1” flat washers, one 1” machine

washers. Slide the side plate weldment (9) over
the end of the hitch and bolt in place as shown

Secure with 1½ slotted hex nut and ¼ x 3 cotter
pin. Use the 1½ machine washers as needed
for proper fit. Connect the turnbuckle (11)
between the side plate assembly and the H-
bracket (1). Use a 1 x 3 3/8 usable clevis pin
(12) with machine washer and 3/16 x 2 cotter
