Servicing the weight stack involves replacing the two
guide bushings and weight insert in the top weight. To
order these 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 guide rod nuts and washers from
the top of each guide rod.
3. Lift the coupler cover and loosen the four set
screws—this will release the cable.
4. Lift the guide rods out of the top of the tower.
5. Remove the rod nut, rod star washer, and rod
washer from the top of the weight tube. Lift and
rotate the top weight, and remove it through the
front opening of the tower.
6. Use a punch to drive the two existing 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. Next, tighten the rod
nut, rod star washer, and rod washer onto the
weight tube.
9. Reattach the cable to the top weight coupler.
Retighten the four set screws into the threaded
holes. Tighten the set screws equally until they
contact the cable. Then, tighten each screw
alternately 1/4 turn, until all are set to 85
inch/pounds (9.6 Newton-meters).
10. Clean and lubricate the guide rods by wiping
them 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 guide rod nuts and washers.
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 nut. 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.
