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.
