This jack can be used with a single-speed power drive kit, part # BD1824200100.

  • Will Bulldog Electric 5th Wheel Landing Gear, part # BD500161 Fit Without Welding
  • There are a couple of things that need to be considered for installation of the Bulldog Electric 5th Wheel Landing Gear, part # BD500161. The welded stops that are on the legs of this landing gear are in specific locations, and require the brackets on your trailer to be attached in corresponding positions so that the landing gear does not shift when installed.

  • How to Flip the Motor of the Bulldog Electric 5th Wheel Landing Gear Set so that it Faces Down

To do that you will need to rotate the motor with the override crank bolt until the pin is at 45 degrees with will allow it to be removed, tap out the pin from the drive shaft and remove pin and washer.

  • How to Wire the Bulldog Powered-Drive Trailer Jack # BD500185 on a Trailer with No Battery
  • The Bulldog Powered-Drive Trailer Jack, item # BD500185, only has one wire, the power wire. This jack attaches to ground through the mounting hardware and the trailer frame. When wiring the jack to your 7-Way trailer connector you will need to make sure that the ground wire from the 7-Way trailer connector is attached to the trailer frame to provide ground. You will then attach the power wire to the 12 volt accessory circuit inside the 7-Way connector or splice into the wire the is attached...

  • Comparison of the Bulldog Heavy Duty Jack Traditional Style Gear Box and a Planetary Style Gearbox
  • The difference between a jack with a traditional gear box and a jack with a planetary gear box is the gears inside the unit, the number of shafts on the unit and the attachment of the units to the jack. The gears in a planetary gear box use gears that can be moved to change speeds, this type of gear box has gears that can be sized very differently also. This gear box can be changed out and the operation of the jack is very smooth. To change speeds on this jack a single shaft is moved...

  • How to Choose the Correct Replacement Trailer Jack With Enough Ground Clearance on Rough Terrain
  • When choosing a jack for your trailer you will want to remember that the jack is not going to be lifting the entire weight of the trailer. You should choose a jack that exceeds the tongue weight of your trailer when it is fully loaded. The tongue weight of a trailer is typically calculated as 10 to 15 percent of the trailer weight. I would recommend finding the gross trailer weight rating (GTWR) which is the maximum weight that your trailer can support and choose a jack that is rated...

  • What is the King Pin Diameter on the Bulldog Gooseneck to 5th Wheel Hitch Adapter
  • The standard king pin dimension for a semi-trailer is 2 inches diameter, where the fifth-wheel jaw wraps around the king pin.

  • Which is Better, a Side Wind Trailer Jack or a Top Wind Trailer Jack
  • You would choose a side wind or top wind jack based on several factors. Each has its advantages. If clearance is an issue for the radius of a top wind, then you would choose a side wind. The opposite is also true. It is my experience that a side winding jack is easier to turn. However, if the tongue is low to the ground a top wind would be a better option because you would not have to bend down as much and it would not be as awkward to turn. A side winding jack normally has inner components...

The legs of the jacks then attach to the brackets. The control panel can be mounted anywhere that is convenient to you. The wiring seems complicated but really it is just power and ground for the switches and...

  • Wiring Recommendation for Charging Trailer Battery through 7-Way without Draining Vehicle Battery
  • You could run the 12 volt accessory circuit to the battery that powers your jack to give it a maintenance charge, but you should note that it would not restore the battery if it was greatly discharged. What I would recommend you do is install a Tow Ready Battery Isolation Solenoid # TR118665 on the 12 volt accessory circuit of your tow vehicle. You would wire it in to the circuit by installing it inline on your 12 volt circuit and then running a keyed power source that only sees voltage...

  • What is the Difference Between a Horizontal Clevis Crank Handle and a Vertical Clevis Crank Handle
  • The clevis in regards to Bulldog 2-Speed Jack, part # BD183816, is the style of the crank handle for the jack. The difference is in the alignment of the pivot point to the rest of the crank handle. A horizontal clevis crank handle when folded up will pivot almost like a wing and lay flat on the side of the trailer when not in use, whereas a vertical clevis crank handle will pivot in like an elbow and fold in to the trailer and be secured in place. In order to pick the right one for...

  • Difference Between the Bulldog Wedge and the Collar Lock Couplers
  • The distance between the center of the ball hole to the center of the circle used for A-frame jacks on the part # BD44125W0317 that you referenced is 12-1/2 inches. I confirmed this with my contact at Bulldog. The advantages between the latching styles of the wedge latch in the # BD44125W0317 and the collar lock like in part # BD028499 is largely personal preference. But the wedge is easier to lock with an anti-theft device. The collar lock style is more rugged and crude design with...

  • If you have a single speed, Bulldog jack rated for 12,000 pounds, like # BD182815, and/or powered drive kit, # BD1824200100, then this is the correct motor.

The 2 speed motor and single speed motor are not identical so you would need to select the correct one based on your Bulldog...
