REMOVAL OF AR2 AND POWER CABLE ASSEMBLY - CONT
3. Use a screwdriver or other suitable tool, inserted through eye of power cable to form a T-
handle. Secure AR2. Pull eye of power cable until the AR2 mechanism reaches the cocked
position and power cable remains extended from power housing (requires approximately 70
4. Unscrew power housing retainer from spring housing and remove power cable assembly by
disengaging ball of power cable from piston rod. Attach storage cable and piston rod cap to
INSPECTION OF POWER CABLE ASSEMBLY PRIOR TO DISSASSEMBLY
1. Shift power cable back and forth inside power housing as far as possible to expose both ends
2. Visually inspect the exposed portion of power cable for fraying. Any fraying or broken strands
of wire indicate a defective power cable, which must be replaced.
3. Move power cable back and forth within power housing. A slight drag due to power cable
seal is normal, but the cable should move smoothly and not bind. If there is any doubt as to
the smoothness of motion, disassemble the power cable assembly and inspect all parts for
wear or damage. Replace any defective parts, including, if necessary, power housing.
The power housing (outer flexible metal casing) must be inspected for looseness
between its convolutions. Looseness indicates either damage or a loss of
interference fit between the outer housing and teflon liner, which maintains the
housing length. Changes in housing length will affect the pulling stroke of the
AR2 and could result in incomplete extraction of ripcord pins.
4. Grasp the outer flexible metal housing casing with both hands, thumbs pointing toward each
other. Hold the housing firmly by pinching between thumbs and fingers. Placement of
thumbs should be two to three inches apart, allowing clear visibility of the casing between
5. Alternately push and pull the housing by applying approximately 10 pounds of force.
Convolutions must not move relative to each other, but be careful not to mistake small
changes in hand position caused by the pushing and pulling action for movement of the
convolutions. Casing should look and feel solid, indicating no movement between
6. Relocate the hand position and apply the procedure at four-inch to six-inch intervals over the
entire length of the power housing. Verify that no movement between the casing
convolutions exists. Any relative movement of the housing convolutions indicates a defective
power housing, which must be replaced.
