S3.23 Assembly and Maintenance Guide
F.Hold the Guide Rods while your assistance replaces the Selector Stem and Top Weight Assembly.
Important: During reassembly, do not lower the Guide Rod Bracket more than three inches along the Guide Rods. Have your assistant hold the Guide Rods firmly because they can be pulled out of the Base Bumpers. It is difficult to replace the Guide Rods in an assembled Weight Stack. If the Guide Rods become dislodged, you will need to disassemble the Weight Stack to make sure that the Guide Rods are seated properly in the Base Frame.
G.Ask your assistant to hold the Guide Rods while you check the cables to make sure they are centered between the Guide Rods. Remove any twists in the cables.
H.To relieve cable tension, lift the Top Cap Weight about a foot above the Weight Stack and secure it with the Weight Pin.
I.While your assistant continues to hold the Guide Rods, realign the Rubber Bumpers with the cutouts in the Upper Frame Crosspiece. Replace the Guide Rod Bracket using two buttonhead screws and two washers (removed in step 2B).
Wrench tighten.
