2. Bolt on the teardrop pulleys above the benches (see Figure 3) using four 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 the figure. You may wish to use a
pinch bar to align the bolt holes.

3. Mount the tops. Mount the 56” lat top to the cell by inserting two of the large 7/16” by 6”
bolts using the hardware configuration shown in Figure 5. Use a 5/8” socket with
extension and combination wrench. Mount the 29” tricep top and adjustable crossover top
to the frame and connecting beam. 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. 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 7. 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- see Figure 6). The 190 lb
weight stacks will need to be facing the “outsides” and “insides” of the cells
(where the tricep pulley and adjustable pulley will be attached- see Figure 6).
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 8 using a 9/16” socket and combination wrench and the 3” bolts
(with cap washers) that were previously inserted.
Figure 8. Bolt on the top plate.
5. Bolt the floating pulley into the 190 lb weight stack using a 7/8” combination wrench
(NOT for the tricep pushdown weight stack- the one with the tricep back rest mounted to
the frame as shown in Figure 7). 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 9. Leave the pulleys out since you will need
to have them out when the cable is routed.
Figure 9. Bolt the floating pulleys into the 190 lb weight stacks.

6. Mount adjustable pulley bracket. When shipped, the adjustable pulley bracket looks
like the one shown in Figure 10. 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 10. 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.
Figure 10. Mount adjustable pulley bracket.
7. Mount the seated row and lat benches to the frame. Using the bolts specified and
9/16” socket and combination wrenches, mount the benches as shown in Figures 11 and
12.

INSTALLING THE CABLES
The SM40 uses four cables. There are three different types of cable used on the SM40. They
are:
1. Adjustable cable (ball end cable) (1).
2. Low row cable (the long cable) (1).
3. Lat pulldown and tricep cables (2).
The lat and tricep cables can be identified by their short length, the low row cable can be
identified by its long length and the adjustable cable 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.

ADJUSTABLE CROSSOVER CABLE ROUTING
Once you’ve removed the pulleys as described previously, route the crossover cable as
shown in Figure 14.

Figure 15. Adjustable crossover cable end detail.
Using a 7/8” wrench, tighten the jam nut onto the adjustable pulley threads as shown in Figure
15. Place a rubber cap on the top of the cable as shown in Figure 15 (right).
LOW ROW CABLE ROUTING
Route the low row cables as shown in Figure 16.

Bolt the cable to the weight stacks as shown in Figure 17. 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.
Figure 17. Screw the cable into the weight stack.
LAT PULLDOWN CABLE ROUTING
Route the lat pulldown cable as shown in Figure 18. Screw the cable into the weight stack as
shown previously in Figure 17.

TRICEP PUSHDOWN CABLE ROUTING
Route the tricep pushdown cable as shown in Figure 19. Screw the cable into the weight stack
as shown previously in Figure 17.
