Today, we're going to be taking a look at and showing you how to install the Bulldog Powered-Drive Kit for Single-Speed Jacks with 12,000-pound capacity, Part #BD1824200100. This powered motor is going to be ideal for horse trailers, livestock or other heavy-duty applications that use the Bulldog Drop-Leg Jack. We're at 12,000 pounds static capacity. With the aluminum gear box and the weather-tight cover that's over it, that's going to keep it maintenance-free and protect it from the elements, to make it last for years to come. Our torque tube does have the energy-absorbing shock in the inside that's going to take and cushion it as it moves from up to down, when we run it. We went ahead and mounted our control panel with our circuit breaker in it up here, underneath the deck of our trailer, so it's going to be even more protected, even though it's in a weather-tight cover. We can operate it from here.
Now, under a normal load, this is designed to go up three inches per minute with a typical load inside your trailer. If you have it severely loaded down in the front, that's going to change according to the amount of weight that you have inside your trailer. Here's what your kit's going to consist of. We're going to have our weather-tight control panel with our up and down. It's also going to have a circuit breaker for resetting. It's going to be a sealed box that's going to mount underneath the tongue of your trailer.
We'll have our junction box that's going to be supplied to attach all our wiring together, our motor that's going to fit into our Bulldog winch, and a cover to cover it up once everything's been installed, to keep the weather out of it. This kit is designed to be used with one or two jacks with the addition of this sleeve here, that you would mount onto a piece of tubing that will go in between the left and the right jack, therefore tying them together, and they'll go evenly up and down. One note: there is some welding involved in installing this. For this application, we're not going to do that, because we're just doing a demonstration, but normally, you would put this rubber grommet onto the motor. Then there's a sleeve that comes with it that it will slide into. This sleeve is going to be welded onto the side of our jack.
That way, when it operates forward and back, it does not allow the motor to flip around on the shaft. It is going to have a rubber in here that's going to actually cushion it, so it's going to get a little bit of movement back and forth. It's going to take all the harshness out of it, cushioning it back and forth. We're going to be going and installing this on a Bulldog jack, part #182404. It's going to be one of our drop-leg jacks. First thing we're going to do is, we're going to remove this handle.
We'll take a 9/16ths wrench and socket. We're going to take the handle and set it aside. We're going to go ahead and remove these 5/16ths bolts. There's going to be one at the top on this side, and one criss-cross on the other side. Take those out. We're going to lift this cover off. Inside, you're going to see our gears. Now, we're going to go ahead and pull this spring back. That's going to give us access to this pin that's right here. We're going to take that pin, and we're going to push it through. You're going to have to hold this spring back all the way. It's going to be a little bit difficult. We're going to drive that pin down out of the way. Then we can rotate it to the top, and we can grab it with a pair of pliers. Once we have the pin out, we can gently take this shaft, and we're going to slide it out. We're going to set that shaft aside. We're going to take our new power jack. We're going to slide it in. We're going to want to rotate, so we line up our pin into our gear, and we're going to reinstall it into the new shaft. We're going to make sure we push it all the way down until the spring will slide back over it, and that's what's going to retain the pin inside of our gear. Now that we have that in place, we can go ahead and reinstall the cap. Now you're going to take this rubber grommet, slip it into place. You're going to take this metal sleeve. We're going to put it on there. We're going to let the motor slide down. You're going to want to clean off all the paint around here, and just put a couple of tack welds all the way around the outside, just being sure you're not going to put a lot of heat into it. Just give it a couple of stitch welds, all around the outside. That's going to secure your motor to the jack. If you're going to be using this to power two jacks, you would take this hex coupler, slide it in. Go ahead and let it bottom out. Then you would get yourself a piece of tubing, and you'd run that tubing between this coupler and the jack handle of the second jack. You would need to weld this onto that piece of tubing, and bolt it through on the other side into the handle. That way, when you turn it on, it's going to run both jacks at the same speed, up and down. As far as your wiring, we're going to have a red and a black wire coming out of our motor. We're going to tie those using our supplied junction box. You would run these through one of the grommets, mounting this wherever you needed to on your vehicle, to be able to access it. Then, coming out of our control panel, our switch, we're going to have a red, a black, a white, and a green. Now, the red and the black are going to be our power and ground, so you would either go from your vehicle's 12-volt source, or, if you have a battery in your trailer, you would power those two, so you'd have your black and red for your battery. Then, going to your motor, you're going to end up with the white wire attaching to the red, and the black wire is going to attach to the green. You would just have them on the inside here. Then you'd use the supplied nut and lock washer, and tighten it down. That's going to keep all your connections sealed up nice and tight. There's going to be a bunch of different rubber grommets with holes, so it will allow you to put them in any of these positions. You want to make sure you silicone up that hole, so no water can get inside there and cause any corrosion. Now, it would be a good idea, if you're using this with a battery, to have a charge wire that runs out of your 7-way connector tied into your system so it charges the battery as you go down the road. That way, you can use your jack whenever you need to, as you get to your time to unload your trailer. Our last step will be install this cover. That's going to help keep it protected from the elements. Should your battery ever become low and not operate your jacks, you can take your handle and replace it back on there, put your bolt into position, and you can use it manually, but you want to make sure that you don't leave this handle attached, because if you're using the electric mode, it's just going to go around, because this is a solid shaft that goes all the way through, so it can cause injury. You want to make sure, unless you're using it for manual, that you leave the handle unattached and stored away inside your trailer. We have one installed here on a horse trailer. You'll notice this one has actually been reversed, because of space confinement here. We went ahead and just put it on backwards, which you can do. It will work either way. In this case, we put the hex on the end of our arm that's going to be used for manual, and we'll just run it backwards. It'll work either way. It's just designed to go the other direction, but if you have something like a spare tire that's mounted there permanently, you have to turn it around and make it work whichever way you can. that's going to do it for our look at the Bulldog Powered-Drive Kit for Single-Speed Jacks with 12,000-pound capacity, Part #BD1824200100.

Jack works great but needed to ad self tapping screws and C clamps for electrical cords ....I had to go and buy both and also batterie cables. Thanks 381363
We installed this on our toy hauler using our existing manual jacks. Install was pretty easy other than you need to weld coupling for tandem usage. Not as strong as I had hoped. Definately slow but beats hand cranking. Have to let it rest twice before it will raise enough to get it on or off the ball and that is with the trailer empty. Don't think it would lift it with the 2800 lb race car inside. Kind of disappointed. 410990
Had to cut the front corner of the trailer to allow for the installation of the jack. Built a battery box to hold a deep cycle marine battery, the jacks power supply is directly for battery, the battery is also charged by the truck . installation was more complex due to the fact that we had to fabricate much more then normal. The jack seem to be just what the doctor ordered. 11922
Just got it today around noon, already installed, works great so far, installation wasn’t bad at all, had to modifie the guard to fix but other than that it was a breeze to install. I’ll let y’all know later if I still like it. 653300
I love the electric jack kit. It was easy to install, wire and operate. No more manual cranking!! Thanks, Clint 574522
Looks to be exactly what I ordered! I ordered this item because as I age I don’t have the same energy. This bulldog product will take the effort out of connecting and disconnecting my gooseneck trailer! 561556
Arrived and box was intake . All items were there and just needed to install on trailer! Shawn B. with ETRAILER was very helpful and professional . 559813
We have bought 2 Bulldog Powered-Drive Kits for single speed jacks from etrailer.com. The first one included the jack also. It was a dream to install and HEAVEN to use on our 4 horse Kingston trailer. The second electric jack is going on our Kingston 2 horse trailer as we fell in in love with the first one!!! 558815
Works well just a bit slower than I exp ected 498833
easy to order, great service and fast s hpg. 486220
Everything so far is excellent I'll try to send a picture when I get it install 482042
I have an older Bulldog jack, it seems. The pin holding the bevel gear was very difficult to remove. It was also an odd diameter -.280" which could not be inserted into the hole in the new shaft. I replaced it with a 1/4" roll pin. Installation of the drive was straightforward and easy. It would have been better to have some installation instructions included. The video on your web site provided all the help needed, though. The drive is SLOW, but immensely better than how slow I was becoming when hand-cranking. Thanks for the fine product. 478612
Product seems to work well, but it is very slow. It is mounted on a 34' load max trailer which is very heavy to begin with. Also if the battery ever dies and you have to crank it by hand, good luck cause between the power it take to move the jacks and the extra power it takes to overcome the brake on the electric motor you will never do it. Overall the product seems good and easy to install. 465660
Had it for a year and still glad I have it, but still very slow, installed a 925cca battery to see if it would help but still slow and very slow in the cold weather. I wedge my leatherman under the switchbox cover and go do something else while it raises.
Installation was a bit tedious because of the trailer construction, but we made the modifications and the bulldog works great!! Saves a ton of wear and tear on my back. 462793
It’s working great and has been trouble free!
The electric jack works very well for me on my 14500 gvw 4 horse trailer. Installation took awhile to complete due to the welding & jack disassembly. It was well worth the time & money spent. 444634
The electric motor for the bulldog jack works great, all the time. Plenty of power to lift the 14,000 lb gooseneck horse trailer. It is surprizingly quiet and the control switch is very heavy duty. The battery and charger installation has been the reoccurring problem.
prompt delivery. Still waiting for customer to come in for installation. 425959
The product arrived on time, and exactly as described. I had one question I posed to customer service, after hours, and was given a response before business opened the following day. This was my first etrailer.com purchase and it was very pleasant...Will certainly recommend. Fyi, I purchased the single speed bulldog landing gear electric conversion kit. 371415
The Bulldog Power Drive Kit came quickly (3 days). I had my local trailer dealer install it for me. They said there were no problems with the installation. It may not be as fast as a hydraulic lift but it is half the price and it sure beats cranking. Some people complained about the noise, I found it to be very quiet. Liked that I have the option of using the hand crank if I don't have a power source. Had it powered with a marine battery in my gooseneck because I didn't want it draining my truck battery and incase I'm not hooked up to the truck. 341431
This Bulldog kit will also fit a Ram 12k jack - been there and done that! 335125
Product is flawless. Easy Install, Excellent instructions. Overall it is a great product. Thanks. 333911
When they say bulldog they mean it! It hauls everything I want to pull. The ball release has worked flawlessly even in the dead of winter when snow and ice are normally a huge issue. Thanks again for a superior product 276422
I installed the power drive kit about 1 year ago to a vac trailer that was very difficult to crank because of it's location and the weight on the hitch. The power drive moves slower that I thought, but it is strong, reliable, and has made hooking and unhooking a breeze! etrailer sent the product to my door as they said they would. 269263
Solidly built and works great. Installation instructions good except for power hook up. 267546
This electric motor for my jack is exactly as it was discribed on the website. It is a huge time saver! I needed this in a rush. Etrailer got it to me right on time. I always buy my parts from etrailer because they have the best selection, best prices and most importantly, the best customer service of any trailer parts company I've dealt with. 235284
Installed perfect and works great. 226736
works well but a bit slow. still beats the crank 215360
works well but a bit slow. still beats the cranl 215359
This product worked very good. Only one problem was the wiring box and the wires coming from the motor. You have to mount the box to close to the motor. Did not give you much option to the placement. Over all very good product?? 183513
We have added this power motor to several of our trailer jacks at Superior Water Light & Power and Minnesota Power. Easy to install and very reliable. Takes the work out of raising a trailer. 179672
We have several in our fleet and they have been holding up great!
Very good product, and really fast ship ping 176668
Excellent item. Works well. 162899
Mounted very easy,slide spring back, drop pin, remove old shaft, slide unit shaft through gear, put pin in, weld stop on jack, hook up preass. wire harness, all marked correct, what made this very nice I got to use my old hand crank, just cut off the amt. shaft shown above, weld your adp. to old crank and replace crank, only thing wires on unit a little short need to be maybe 6in longer, also used old gears, pushed button jack lifted 3horse LQ trailer faster than by hand, very satisfied . 162675
Excellent product easy to install fast shipping!! 149347
Works great. 146182
This thing was nightmare to install. I figure it would be. Little difficult but not as bad as it was. I was putting mine on an older bulldog jack which did not have the spring holding the pin in the gears. It took several hours to just get the shaft out of the jack. I almost cutoff the jack and welded on a new one. Once I finally got it installed the motor is so slow it's not even funny. And because I had too install mine opposite of the way it was intended the cover won't go on so now I need to have a cover made for it. At least it was cheaper than a hydraulic unit. 146021
The Power drive kit was shipped within a few hours and was exactly as described. I installed it on a gooseneck horse trailer. As the spare tire was on the side where the motor is shown, I installed it on the other side. It said that the drive gear in the jack should be on the opposite side to the motor, so I moved the gear to the other side. The original gears were used as the ones provided were not suitable for the jack. As an upgrade I installed a thin oilite shim between the gear and the inside of the jack housing. Having a lathe is beneficial! Now of course the hex drive is on the crank side of the unit so I made an adaptor so that the crank can be used on the hexed end of the drive shaft in case of a battery failure. The wiring was very well done and I only had to provide battery power and ground to the terminal box provided. I have a neighbour that does a lot of G M work so he had the correct clips for mounting the wire harnesses. you should perhaps look at puting a few of these in the kit. I used 5 of them to secure the harness. 74154
After one double check with one of the company's techs - things went well and very smooth - Thanks my back is screaming for Joy not Pain 72470
Nice product. Easy to install. Works great. We have alot of heavy trailers that get used every day, these electric jacks make life a lot easier on our shoulders. Chris 59283
It sure makes hookingup our gooseneck horsetrailer so much easier. Works great! Easy to install and easy on my back. 54614
very good product ! easy to install. directions could be clearer on wheather to use the suppiled gears for the gear box .the way i took it, i had to replace them in the ONE speed jack. so took it all apart,the supplied gears were to big. so put it all back together, useing the stock gears, worked fine !! 44469
shipping was excellent.Will try and mount it tomorrow. 32146
No complaints yet, and I complain alot. 10131
Easy to install . works great no more cranking by hand 9321
I highly recommend etrailer. They were very knowledgable and answered all my questions and concerns I had with their product. The shipment arrived very quickly. I couldn't be happier. Wish everyone were as as efficient as etrailer. 6896
