Bulldog Electric Powered Drive Motor For 12K Single Speed Trailer Jack Includes Replacement Gear Kit Install Notes
Installation Instructions for Powered Drive for Jacks
Tools Required:
- Welding equipment (performed by an AWS-certified welder)
- Standard tools for bolts, nuts, and wiring
Safety Instructions:
- Never position any part of the body under the jack or supported load.
- Fully retract and/or rotate the jack before towing.
- Ensure the drop leg pin is fully inserted before using the jack.
- Avoid excessive side forces to prevent jack failure.
- Disconnect the battery ground cable before installation to prevent electrical shock.
- Replace bent, broken, or worn parts before use.
Installation Instructions:
Step 1: Remove the Jack Cross Shaft
- If the jack has non-welded hex bushings, consult the manufacturer's service bulletin for instructions.
- For planetary two-speed jacks, refer to the manufacturer's guidelines or specific service bulletins.
Step 2: Install the Powered Drive
- Temporarily replace the jack cross shaft with the powered drive/shaft assembly.
- Install the shaft on the non-geared side of the jack, ensuring the motor is facing downward and within the jack's profile.
Step 3: Position the Torque Stop Tube
- With the powered drive temporarily installed, use it to locate the torque stop tube on the jack's outer tube.
- Mark the location of the torque stop tube and weld it to the jack's outer tube using AWS-certified welding procedures.
Step 4: Final Assembly
- Reinstall the powered drive/shaft and place the energy-absorbing rubber bumper into the torque stop tube to prevent motor rotation.
- Attach the powered drive cover using 1/4” x 1” bolts and rubber-bonded washers. Torque bolts to 6 ft-lbs.
- Optionally, apply thread lock to the bolts.
Step 5: Tandem Jack Systems
- Use the included hex coupling to connect tandem jacks.
- Weld the coupling to a 1” Schedule 40 pipe and cross-drill a 3/8” hole to secure the second jack's cross shaft with a bolt and locknut.
Wiring Instructions:
- Disconnect the battery ground cable.
- Attach the terminal box to the trailer for connection of powered drive and harness leads.
- Route and secure all leads using non-split tubing or loom.
- Mount the switch box at a convenient location on the trailer.
- Reconnect the battery ground cable and test the powered drive operation.
- Seal all terminal box entrances with sealant to protect the wiring.
Operation:
- Raising the Trailer: Extend the drop leg and fully engage the pin. Press the "RAISE" switch until the trailer is fully lifted.
- Lowering the Trailer: Press the "LOWER" switch until the trailer rests on the ball and the jack is no longer under load.
- In the event of power loss, reset the breaker or manually crank the jack using the powered drive assembly.
Maintenance:
- The powered drive is sealed and maintenance-free.
- Regularly maintain the jack and battery system. Ensure all connections are tight and free of corrosion.
- Fully charge the battery before use.
Limited Warranty:
