SM63 Unpacking & Assembly Instructions

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.
