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.

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).

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.

6. Using a 7/8” combination wrench, bolt the floating pulleys into the 190 lb weight  
stacks (except for the tricep pushdown weight stack- the one with the tricep back rest  
mounted to the frame as shown in Figure 10). You will need to remove the pulley from  
the housing to thread the plug into the weight stack bayonet. Make sure the 9/16” jam  
nut is threaded 1-5/8” away from the pulley as shown in Figure 12. Leave the pulleys  
out since you will need to have them out when the cable is routed.  
Figure 12. Bolt the floating pulleys into the 190 lb weight stacks.  
7. Mount adjustable pulley brackets. When shipped, the adjustable pulley brackets look  
like the ones shown in Figure 13. The bolts need to be removed and the bracket  
needs to be positioned so that the top of the bracket is in the top hole as shown by  
the arrow in Figure 13. Use a 3” bolt with flat washers, end cap washers and end  
caps. When you remove the bolts, leave the pulley bolt and pulley out since you will  
need to thread the cable with the pulley removed.

8. Mount the seated row and lat benches to the frame. Using the bolts specified in  
Figure 14 and a 9/16” socket and combination wrenches, mount the benches as  
shown in Figures 14 and 15.

SM83 Unpacking & Assembly Instructions  
INSTALLING THE CABLES  
The SM83 uses eight cables. There are three different types of cable used on the SM83. They  
are:  
1. Adjustable crossover cables (ball end cables) (3).  
2. Low row cable (the long cables) (2).  
3. Lat pulldown and tricep cables (3).  
The lat and tricep cables can be identified by their short length, the low row cables can be  
identified by their long length and the adjustable crossover cables can be identified by the ball  
on the end of the cable. The routings for these cables are shown in Figures 16, 17, 18 and 19  
below.  
NOTE: YOU MUST REMOVE ALL PULLEYS TO ROUTE THE CABLES.  
USE A 9/16” COMBINATION WRENCH AND SOCKET TO DO THIS  
(SEE FIGURE 16). YOU MAY WISH TO REMOVE THE SHOULDER  
BOLTS (FIGURE 16 RIGHT SIDE) BY USING A 3/8” COMBINATION  
WRENCH AND A 1/8” HEX KEY WRENCH. WHEN YOU HAVE  
ROUTED THE CABLES, REPLACE ALL PULLEYS AND PLACE  
END CAPS ON NUT AND BOLT ENDS. YOU MAY NEED TO PRY  
THE PULLEY HOUSINGS OPEN TO REPLACE THE PULLEYS.
