POWER AND SENSOR COIL CORD REPLACEMENT
Required Tools:
#2 Phillips Screwdriver Side Cutters
Bungee Cord (or equivalent) 5/16” Nut Driver
5/16” Socket Wrench
Procedure:
1. Unplug the bed power cord from the wall socket.
2. Using a 5/16” socket wrench, remove the six bolts holding the lower lift cover to the base and remove
the cover.
3. Using a #2 Phillips screwdriver, remove the three screws holding the upper lift cover to the base.
4. Using a #2 Phillips screwdriver, remove the four screws holding the litter access panels at the end of the
bed needing service.
5. Using side cutters, cut the cable ties holding the power and sensor coil cords to the base. Remove the
ground wire coming from the sensor cord that is attached to the base (note the star washer arrangement).
6. Disconnect the cables going to the motor and the lift potentiometer (at the head end, the sensor cord is
also attached to the brake switch sensor).
7. Pull both cords up through the frame of the bed and the lift housing.
8. Using a 5/16” nut driver, remove the two screws (A) holding the cable clamps* to the top of the lift housing.
9. Using a 5/16” nut driver, remove the two screws (B) securing the cable clamps* to the underside of the
header crossbar assembly.
10. Pull both coil cords up through the header crossbar assembly.
11. Disconnect the power and sensor coil cords from the connectors.
12. The cords should now be completely removed from the bed. Reverse the above steps to install the new
power and sensor cords*.
CAUTION
*When the power and sensor coil cords are being replaced, secure the cable clamps to the cords at the first
coil on the top and on the bottom to assure there is not too much slack in the cords between the top of the
lift housing assembly and the bottom of the header crossbar. Be sure the clamps are fastened at exactly the
correct angle, as shown by the arrows in the illustration. Arrange the cords exactly as shown in the illustration
(left in front of right). If this is not done correctly, damage to the cords will result.
