50, and 51.
5.
Bolt clevises on bushings 1, 3, and 4 of each front tandem link, on bushings 2 and 4 of each
second suspension link, on bushing 2 of each third suspension link, and on bushings 2 and 4 of
each rear suspension link.
6.
Install a clevis on bushings 54 and 55 in an inverted position on each platform side rail. Bolt one
additional clevis to each inverted clevis.
7.
Starting at the front of the platform, install clevises on each platform side rail using the
bushings bolted on holes 10, 14, 17, 18, 26, 30, 31, 37, 40, 41, 42, 44, 46, 53, and 56.
