WEIGHT STACK SERVICING
For required parts, see HOW TO CONTACT CUS-
TOMER CARE on the back cover of this manual.
1. Remove the access cover by pulling it free at the
bottom and then sliding it upward until the two sets
of tabs release.
2. Loosen the top bolt or nuts on each guide rod.
Remove the bolts or nuts and let the guide rods
slide down to the floor.
3. To remove the top weight, use a 5/16" hex key and
a 9/16" open-end wrench to unbolt the pulley(s)
and release the cable.
4. Slide the top weight off the top of the guide rods.
Note: Pull the guide rods toward the back of the
machine for increased clearance.
5. 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.
Small
Bushings
6. 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 surface.
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.
7. Clean and lubricate the guide rods by wiping them
using a soft cloth containing automotive engine oil.
Apply only a light coating over the entire length.
8. Replace the top weight on the guide rods. Bolt the
pulley, cable, and cable guards into place.
9. Reattach the guide rods to the top of the frame.
10. Insert the weight pin into the top weight. Pull the
handle, lifting the top weight all the way to the top.
Slowly return the handle to the resting position. If
the top weight sticks, loosen one of the guide rod
bolts or nuts. Lift the top weight to the top again.
Retighten the guide rod bolt or nuts. Check the full
travel again and readjust the guide rods if neces-
sary.
11. While slowly pulling the handle, have another per-
