SERVICING THE WEIGHT STACK
For required parts, see HOW TO CONTACT CUS-
TOMER CARE on the back cover of this manual.
1
. Remove the wingnuts under the tower cap and
remove the tower cap from the tower.
2
. Remove the screw 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
two guide bushings and weight insert in the top
weight. First, use a punch to drive the two exist-
ing guide bushings and weight insert out of the
top weight.
7. To insert the new bushings and weight insert,
hold a 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 bushing should be flush
with the surface. Repeat with the other bushing
and weight insert.
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
t
hem with a soft cloth containing a lightweight
motor oil, 10W-40 or 10W-30 weight. Apply only a
light coating over the entire length. Note: Do not
use TEFLON
®
or silicone-based lubricants.
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 screws.
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 screws. Lift the top weight to the top
again. Retighten the guide rod bolt. Check the
full travel again and readjust the guide screws as
necessary.
14. While slowly pulling the handle, have someone
check the cable guard on the top weight to
ensure that it is not dragging or rubbing on the
cable.
15. Replace the tower cap and retighten the
wingnuts onto the bolts.
