3-8.1 Disc gangs are partly assembled at the
factory. Some assembly is needed before
installing on the frame. A special wrench is
used to tighten 1-1/2" nuts on the disc
gangs.
3-8.2 Assemble the flex mount shanks to the
disc bearing mounts using 3/4-10 x 2-1/2 cap
screws. Be sure the open end of the flex
shank is facing the rear of the disc gang.
3-8.3 Insert the disc gang mounting pins into the
disc gang tubes (2 per tube). Assemble the
disc gang tubes to the flex shanks using u-
bolts, mounting plates, spacer plates, and
nuts. The two shorter tubes are for the front
disc gangs. The two longer tubes are for the
rear disc gangs.
