2. Bolt on the teardrop pulley above the bench (see Figure 4) on the 4 stack cell 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 nut. Use the bolt configuration shown in Figure 5. You may wish  
to use a pinch bar to align the bolt holes.

extension and combination wrench, to the cells 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 cells.

4. Mount the 56” lat top (part T from HARDWARE section) to the 4-stack cell using a  
5/8” socket and combination wrench. Insert two of the large 7/16” by 6” bolts using the  
hardware configuration shown in Figure 7. Mount the 29” tricep top (part U in  
HARDWARE section) to the frame and connecting beam (See Figure 7). 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.

5. Mount the weight stacks to the 3-stack cell. To do this:  
A. Remove the tricep back rest bolts using a 9/16” socket and combination  
wrench (see Figure 9).  
B. Unbolt the top plate and remove the guide rods using a 9/16” socket and  
combination wrench (see Figure 9).

Bottom plate  
Figure 9. Remove the tricep back rest, the top plate and the guide rods.  
C. Prepare the weight stack-  
add bumpers to bottom, insert  
guide rods, put pull pin in  
bottom plate of stack.  
D. Flip over the weight stack  
onto piano dolly.  
E. Hoist the weight  
stack onto the machine.  
Figure 10. Putting on the weight stacks.  
C. Prepare the weight stacks. Slide the guide rods (2) through the weight stacks  
(1) as shown above. 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).

SM41 Unpacking & Assembly Instructions  
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). Make sure all  
pull pins are facing outward.  
F. Bolt on the top plate. 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.  
Figure 11. Bolt on the top plate.  
6. Bolt the floating pulley into the 190 lb cable crossover weight stack (NOT  
intended for the tricep pushdown weight stack- the one with the tricep back rest  
mounted to the frame as shown in Figure 9) using a 7/8” combination wrench. 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.

7. Mount the lat bench to the frame. Using the bolts specified in Figure 13 and a 9/16”  
socket and combination wrenches, mount the lat bench as shown in Figures 13 and  
14.

INSTALLING THE CABLES  
The SM41 uses four cables. There are two different types of cable used on the SM41. They  
are:  
1. Crossover cables (ball end cables) (2).  
2. Lat pulldown and tricep cables (2).  
The lat and tricep cables can be identified by their short 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 the figures below.  
NOTE: YOU MUST REMOVE ALL PULLEYS TO ROUTE THE CABLES.  
USE A 9/16” COMBINATION WRENCH AND SOCKET TO DO THIS  
(SEE FIGURE 15). YOU MAY WISH TO REMOVE THE SHOULDER  
BOLTS (FIGURE 15 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.

CROSSOVER CABLE ROUTING  
Once you’ve removed the pulleys as described previously, route the crossover cables on the  
4-stack cell as shown in Figure 16. The crossover cable is routed at the factory on the  
1-stack cube.

LAT PULLDOWN CABLE ROUTING  
Route the lat pulldown cable as shown in Figure 17. Screw the cable into the weight stack as  
shown in Figure 18.  
Figure 17. Lat pulldown cable routing.  
Bolt the cable to the weight stacks as shown in Figure 18. Thread the 7/8” nut up on the  
cable bolt as shown at left. Screw the bolt down into the weight stack as shown at right.  
Tighten the bolt with a 7/8” combination wrench.

as shown previously in Figure 18.
