Wing Pivot Arm Installation and Ball Joint Service
When assembling wing pivot arms, adjust ball joint
thread engagement to get a length of 8.06" for proper
blade plane setting, then tighten jam nut (also see Blade
Adjustment).
IMPORTANT: Before installing wing pivot arms,
clean tapered surfaces of ball joints and mounting
bosses on deck with solvent degreaser.
Apply Loctite 242 or equivalent to nut securing ball joint
and tighten to a torque of 150 - 180 ft-lb. Make sure two
(2) flat washers are installed under nut.
