2. Remove the lower link bolt and nut.
3. Roll the intermediate frame (where the link is still attached) counterclockwise until the
upper link pin can be accessed. It may be helpful to use a jack or strap between the boom
frame and the intermediate frame. Remove the snap-ring from the link pin. Remove the
pin and link.
4. Install the cylinder (H75) into the lower mount so that the cylinder ports face the front of
the sprayer. Ensure the pivot sleeve is installed into the cylinder. Install the bolt through
the cylinder and sleeve and torque to 250 ft-lbs (339 Nm).
