WEIGHT STACK SERVICING
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 rod. 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 bush-
ings and the weight insert out of the top weight.
7. Hold one of the new guide bushings square to the
face of one of the holes in the top weight, place a
protective piece of wood on top of the guide bush-
ing, and lightly tap the guide bushing until it is flush
with the surface.
Insert the other guide bushing
and the weight insert in the same way.
8. Replace the top weight. Next, tighten the rod nut,
rod star washer, and rod washer onto the weight
rod.
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 alter-
nately 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.
Do not use TEFLON
®
or sili-
cone-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 into the top weight. Slowly per-
form a repetition, lifting the top weight as far as
possible. Then, slowly lower the top weight. If the
top weight sticks, loosen one of the guide rod nuts.
Slowly perform another repetition. Retighten the
guide rod nut. Check the full travel again and read-
just the guide rod nuts as necessary.
14. Slowly perform a repetition using a light load and
have someone make sure that the cable is not
derailed from a pulley or rubbing on a cable
guard.
15. Replace the tower cap and retighten the wingnuts
onto the bolts.
