Start with the rear disc gangs. Position them under

rear swing arms and raise the back of the disc up to
lower the front swing arms.

u-bolts over the swing arms into the mounting
bracket holes. Take care to make sure the long
u-bolts are mounted in the holes located farthest
from the mounting bracket’s vertical leg.
4. Continue lowering the swing arms until they are
touching the mounting bracket flanges.
5. Install 3/4" hex flange top locknuts (#3B) to the short
u-bolts (#6). Draw nuts up loosely.
