1. Place the two weight “cubes” in their “final resting spots.” The cubes will be
approximately 11’4” apart as shown in Figure 3.

Figure 3. Set the weight stack cubes.
2. Bolt on the teardrop pulley assemblies above the benches (see Figure 4) on both
cubes using two 3/8” x 2-3/4” hex head bolts. Include the 3/8” flat washer, end cap
washers, end caps and 3/8” Nyloc (locknut). Use the bolt configuration shown in
Figure 5. You may wish to use a pinch bar to align the bolt holes.

3. Using a 5/8” socket with long extension and combination wrench, bolt on the
connecting beam to the cubes using two of the large 7/16” x 6” bolts, 7/16” washers,
and 7/16” nuts, end cap washers and end caps. Figure 6 shows the connected cubes.
You will need to remove the pulleys from the teardrop pulley assemblies to gain
clearance for the socket wrench extension. Leave the pulleys out of the housings until
the cables have been installed.

4. Using a 5/8” socket and combination wrench, mount the 56” lat tops (part T from
HARDWARE section) to the cells by inserting two of the large 7/16” by 6” bolts using
the hardware configuration shown in Figure 8. Mount the 29” tricep top (part U in
HARDWARE section) and adjustable crossover top (part V in HARDWARE section)
to the frame and connecting beam (See Figure 7). You will need to remove the
teardrop pulleys from their housings to gain clearance for the socket extension used
to tighten the bolts on the tops. Use a 9/16” socket and combination wrench to do
this.

5. Install the weight stacks. To do this:
A. Using a 9/16” socket and combination wrench, remove the tricep back rest bolts
(see Figure 10).
B. Using a 9/16” socket and combination wrench, unbolt the top plate and remove
the guide rods (see Figure 10).
Figure 10. Remove the tricep back rest, the top plate and the guide rods.

C. Prepare the weight stack. Slide the guide rods (2) through the weight stacks (1)
as shown below. Place rubber bumpers (3) on the bottoms of each guide rod.
Make sure the pull pin (4) is in the bottom weight plate.
D. Flip over the weight stacks. When shipped, the weight stacks have the pull pins
facing upward. You will need to flip the stacks over so that the pull pins are facing
outward when they are loaded onto the machine. Since the pull pins will be facing
downward when they are flipped over, it is recommended that you put the stacks
on a padded carpet to keep the pins from being damaged.
E. Set the weight stacks onto the machine. Using a piano dolly, lift the weight
stacks over the bottom plate and set the stacks onto the rubber bumpers with the
plate numbers facing outward. The 300 lb weight stacks need to be facing the
“sides” of the cells (where the benches will be attached- number 8 in Figure 9).
The 190 lb weight stacks will need to be facing the “outsides” and “insides” of the
cells (where the tricep pulley adjustable pulleys will be attached- number 9 in
Figure 9). Make sure the pull pins are facing outward.
C. Prepare the weight stack-
add bumpers to bottom, insert
guide rods, put pull pin in
bottom stack. D. Flip over the weight stack
onto piano dolly. E. Hoist the weight
stack onto the machine.
F. With the top plate on the guide rods, bolt on the top plate to the top of the cells as
shown in Figure 11 using a 9/16” socket and combination wrench and the 3” bolts
(with cap washers) that were previously inserted.
