Figure 3. Set the weight stack cubes.
2. Bolt on the teardrop pulleys above the lat benches (see Figure 4) on both cubes using
two 3/8” x 2-3/4” hex head bolts (used to bolt the cross beam to the cross members
and the adjustable pulley tops to the top beams). 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 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.

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 7. Mount the 29” tricep top (part U in
HARDWARE section) to the frame and connecting beam (See Figure 6). 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. Install the weight stacks. To do this:
A. Using a 9/16” socket and combination wrench, remove the tricep back rest bolts
(see Figure 9).
B. Using a 9/16” socket and combination wrench, unbolt the top plate and remove
the guide rods (see Figure 9).
Figure 9. 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). 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 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 10 using a 9/16” socket and combination wrench and the 3” bolts
(with cap washers) that were previously inserted.
Figure 10. Bolt on the top plate.
6. Using a 7/8” combination wrench, bolt the floating pulleys into the 190 lb weight
stacks (except for the tricep pushdown weight stacks- the one with the tricep back

rest mounted to the frame as shown in Figure 9). 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 11. Leave
the pulleys out since you will need to have them out when the cable is routed.
Figure 11. 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 12. 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 12. 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 12. Mount adjustable pulley bracket.
8. Mount the seated row and lat benches to the frame. Using the bolts specified in
Figure 13 and a 9/16” socket and combination wrenches, mount the benches as
shown in Figures 13 and 14.

INSTALLING THE CABLES
The SM61 uses six cables. There are three different types of cable used on the SM61. They
are:
1. Adjustable crossover cables (ball end cables) (2).
2. Lat pulldown and tricep cables (4).
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 15, 16, 17 and 18
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 three adjustable
crossover cables as shown in Figure 16.

Figure 17. Adjustable crossover cable end detail.
Using a 7/8” wrench, tighten the jam nut onto the adjustable pulley threads as shown in Figure
17. Place a rubber cap on the top of the cable as shown in Figure 17 (right).
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.
Figure 18. Screw the cable into the weight stack.

LAT PULLDOWN CABLE ROUTING
Route the lat pulldown cable as shown in Figure 19. Screw the cable into the weight stack as
shown previously in Figure 18.
Figure 19. Lat pulldown cable routing.
TRICEP PUSHDOWN CABLE ROUTING
Route the tricep pushdown cable as shown in Figure 20. Screw the cable into the weight stack
as shown previously in Figure 18.

beam, lat top beams, and connecting beam to the tops of the cubes)
B. 3/8” x 3” hex head bolt (used to bolt the cross beam to the cross members, the
adjustable pulley tops to the top beams, and the bottom bolts on the lat benches)
C. 3/8” x 2-3/4” hex head bolt (used for all other connections)
D. End caps (bolt covers)
E. 7/16” flat washer
F. 7/16” cap washer (used on the head end of the 6” bolt so end cap will fit on the nut)
