SERVICING THE WEIGHT STACK
For required parts, call our Customer Service
Department at 1-800-201-2109.
1. Remove the wingnuts on the bottom side of the
tower cap and remove the tower cap from the
tower.
2. Remove the bolt from the top of each guide rod.
3. Lift the coupler cover and drive the roll pin from
the top weight coupler with an 1/8” punch and a
hammer—this will release the cable.
4. Lift the guide rods out of the top of the tower.
5. Lift and rotate the top weight and weight pin, and
remove them through the front opening of the
tower.
6. Servicing the weight stack involves replacing the
three bushings in the top weight. First, use a
punch to drive the three existing bushings out of
the top weight.
7. To insert the new bushings, hold each bushing
square to the face of one of the holes in the top
weight, place a protective piece of wood on top
of the bushing, and lightly tap the bushing into
place. The bushings should be flush with the sur-
face.
Note: There are two sizes of bushings. The
slightly larger bushing is for the single hole
in the top weight; the smaller bushings are
for the top and bottom of the cylindrical
standoff.
8. Replace the top weight and weight pin on top of
the weight stack.
9. Reattach the cable to the top weight coupler.
10. Clean and lubricate the guide rods by wiping
them with a soft cloth containing TEFLON
®
oil.
Apply only a light coating over the entire length.
11. Reinsert the guide rods through the top of the
tower and into the weight stack.
Note: If the weight stack has shifted, use a
short bar to realign the holes in the weight
plates. Hold the weight plates while inserting
the guide rods.
12. Reattach the guide rods to the top of the frame
with the two bolts.
13. Insert the weight pin in the top weight. Pull the
handle, lifting the top weight all of the way to the
top. Slowly return the handle to the resting posi-
tion. If the top weight sticks, loosen one of the
guide rod bolts. Lift the top weight to the top
again. Retighten the guide rod bolt. Check the
full travel again and readjust the guide rods as
necessary.
14. While slowly pulling the handle, have someone
check the top weight pulley guard to ensure that
it is not dragging or rubbing on the cable.
15. Replace the tower cap and retighten the
wingnuts onto the button bolts.
