Alternate Instructions- Atwood Ball Screw Jack
CAUTION !!! IF YOUR JACKS ARE ATWOOD BALL SCREW TYPE(HAVE TUBE-WELDED TO SIDE OF THE GEAR
BOX), AND YOUR CAMPER IS NOT ON YOUR TRUCK, SUPPORT IT ON BLOCKS SO THAT ANY JACK CAN BE
REMOVED WITHOUT THE CAMPER BECOMING UNSTABLE.
The foregoing mechanical instructions apply to the Atwood Acme Screw Drive Jack. The Atwood Ball Screw Drive Jack has
two major variations in design, which change the Acme Screw Drive jack installations as follows:
1.
It has a tube which houses the manual crank. This tube is welded to the gear box housing, and must be
removed as it is no longer needed. Remove it with a hack saw and grind it flush with the side of the gear box.
(see sketch below)
2.
The horizontal bevel gear is held in place by a nut, which must be removed. If the nut is round and knurled,
use a vise-grip pliers to take it off. If the nut is hex head, use a 14 mm open end wrench.
3.
Lift the horizontal bevel gear and the ball bearing off the jack post drive pin. Keep the loose drive pin in the
jack post.
The electrical installation instructions are almost the same. Since the ball screw is a right hand thread, you must
connect the red wire to the negative terminal and the black wire to the positive terminal on the receiver terminal
strip connecting the receiver to the jacks. This will cause jacks to go up when the up button is pressed on the
transmitter. Do not do this to the power terminals. On power terminals, connect the red wire to the positive
terminal and the black wire to the negative terminal. If any existing wiring is in the camper from a previous
installation, discard it and install new to assure the proper wire size and circuitry. Remote controlled electric
jacks require different circuitry than switch operated electric jacks.
In addition to the tools listed as required, add a hand hacksaw, a vise-grip pliers (or 14mm open end wrench) and a
portable hand grinder or file.
