IMPORTANT: When applying the Loctite® threadlocker
to the threads of the bushing and the capscrews you
have a maximum of ten minutes to line the counterweight
up and insert all four capscrews. The threadlocker will
start to set-up after ten minutes.
1. Insert the four threaded bushings (5) into the square
holes in the vehicle frame. Apply a few drops of
Loctite® threadlocker #277 to the threads of each
bushing.
2. Be sure the counterweight insert (6) is in place in the
"pocket" inside the counterweight.
3. With the counterweight on the transport pallet (1),
use another piece of equipment to lift the pallet up.
Line up the holes in the counterweight (4) with the
threaded bushings.
4. Apply Loctite® threadlocker #277 to 1-1/2" of the
engaging threads of each capscrew (2).
5. Assemble the flat washers (3) onto the
capscrews (2) and insert the capscrews with flat
washers into the mounting holes in each side of the
counterweight. Thread the capscrews into the
threaded bushings (5) in the frame. Torque all
capscrews to 680 lb/ft (922 Nm).
