13-2 Follow this sequence to install the cable:
a. Start threading the cable into the left side
between the two pulleys of the Adjustable
Dual Pulley system (Figure 17).
b. After you thread the cable through the left
side, direct the cable down in front of the
bottom 4 1/2” pulley.
Note: Make sure to thread the cable between
the groove in the pulley and the thread guide
welded to the frame.
c. Continue threading the cable to the 6”
bottom pulley and up behind it.
Step 13: Thread Cable Through Pulley Assemblies,
continued
d. From there, thread the cable all the way up
over the 6” pulley on the right side and back
down in front of the Weight Stack Pulley
Assembly (Figure 18).
e. Thread the cable under the Weight Stack
Pulley Assembly and up behind it.
f. Going up again, thread the cable over
the 6” pulley on the right side of the Tower
and under the 4 1/2” pulley on the Row
Attachment Assembly (Figure 19).
g. Attach the remaining washer, Cable Ball, and
Slotted Strap Fork.
Figure 19:
Note: To align the Weight Stack Pulley, first
make sure that the tension nuts are loose
(assembly should rotate freely) and that all
other steps have been completed.
With the weight pin inserted (amount of
weight is unimportant; simply ensure there is
some weight), pull the cable handles until the
cable is just tight. This should rotate the
pulley to the correct orientation. Tighten the
tension nuts while the cable is tight.
13-3 Tighten the hardware on the Top Pulley
Assemblies.
14-1 Lubricate the guide rods using a silicone based
lubricant.
14-2 Carefully inspect all cables and insure that they
are properly seated on the pulleys and that they
pass between the pulleys and cable retainers.
14-3 Make sure all hardware is securely tightened.
Cable Tensioning
14-4 The cables should be as tight as possible while still
allowing the selector pin to freely engage all of
the weights.
14-5 Once the cables are tensioned, load the weight
stack with as much weight as you feel comfortable
with, and pull each cable several times to set and
stretch the cables.
14-6 After the cables are stretched, they may need to
be re-tensioned.
14-7 Over time, the cables may stretch and need to be
re-tensioned.
When cables are properly tensioned, the ball stop
should rest within 1/4” of the Dual Pulley System and
the top weight should sit flush. If the cable is loose
(more than a 1/4” of play), move the bottom tension
nut up the bolt. Next, screw the bolt further down into
the weight stack. If the cable is too tight, unscrew the
bolt from the Weight Stack. Finish by retightening the
bottom tension nut. Make sure to follow the guidelines
above regarding thread engagement.
