Vitality Series Selectorized Line Abdominal / Back Extension Assembly Guide: Assemble the Equipment 5
Attach the Movement Arm to the Cam Mounting Plate and Base
Support
Note: To simplify this procedure, you may want to back out the set screws on the
two pillow-block bearings before you begin.
1. Attach the movement arm to the pivot support. Slide the round end of the
axle into the pillow-block bearing on the pivot support until it stops. Tighten
the two set screws to hold the axle in place.
2. Have your assistant support the movement arm while you guide the
movement arm onto the axle. Have your assistant continue to support the
movement arm.
Note: There are two metal flanges on the pulley arm assembly. Position
these stops so that they rest on top of the stops on the cam support plate
and on the cam itself.

3. Slide the cam and pulley arm assembly onto the axle, making sure that the
rubber stops on the cam are facing the cam support plate (and facing away
from the user).
4. Slide the pillow-block bearing over the end of the axle until it stops.
5. Insert the cam support plate into the slot in the weight tower frame and
attach it
securely using:
3 – M12 x 65 mm hex head bolts
3 – 13 mm flat washers
Note:
The cam support plate can be tightened completely.
