Installation Instructions:

1. Remove the jack cross shaft as instructed in the included Service Bulletin (F3310 for non-welded hex bushings or F3376 for a planetary two-speed jack).
2. Temporarily replace the jack cross shaft with the powered drive/shaft, ensuring the powered drive is on the non-geared side of the jack with the motor down and within the profile of the jack.
3. With the powered drive/shaft installed, position the torque stop tube on the jack's outer tube wall.
4. Mark the location of the torque stop tube on the outer tube and remove the powered drive/shaft. Weld the torque stop tube onto the marked location on the jack's outer tube.
5. Reinstall the powered drive/shaft, ensuring the energy-absorbing rubber bumper is placed into the torque stop tube during assembly to prevent motor rotation.
6. Follow the appropriate Service Bulletin (in reverse order) to reassemble the jack, using the standard hole for normal installation (do not use hole #2).
7. Attach the powered drive cover using the included ¼” x 1” bolts and ¼” rubber bonded washers, sandwiching the cover between the washers with the rubber side against the cover. Secure the bolts into the mounting flange holes, torquing them to 6 ft. lbs. Optionally, use a thread lock or retaining compound on the bolts. Apply the Bulldog decal to the outside of the cover.

Wiring Instructions:

1. To ensure safety and prevent electrical system damage, disconnect the battery ground cable.
2. Attach the terminal box to the trailer at a suitable location for connecting the powered drive leads to the terminal box studs (refer to Figure 5 for the wiring diagram).
3. Connect the powered drive leads and wiring harness leads to the terminal box studs. For added protection, enclose the leads in non-split tubing or loom (included).
4. Mount the switch box of the wiring harness at the desired location on the trailer (mounting hardware not included).
5. Connect the battery leads to the terminal box studs and attach the terminal box cover.
6. Reconnect the battery ground and test the operation.
