Video Transcript for Powered Trailer Jack Installation

Today we are going to install part number BD500185 from Bulldog. This is their powered jack. The jack is ready for 4,000 pounds and it should be pretty easy to install. The first step involved is to remove the old jack and any accessories with it. We will lower the trailer on some jack stands. Get the jack loose. We have got a battery box for the brake away kit so lets take that apart and loose and out of the way. Once you have the stuff around the jack out of the way we will unbolt the jack from the tongue. Once we have got it unbolted we can pull it straight out. 00:43

We will install the power jack the same way we uninstalled the original jack. Line up the bolt holes, whichever ones match up the best. You have got a couple of different patterns on here. Get the wire out of the way. We are going to install the jack reusing the original hardware because of the higher grade than the original stuff that comes with the jack. We will reattach it that way. We can run the wiring out to the power supply. We will put our break away battery kit back into place. 01:14

Now we will run our power supply wire into our tool box in the trailer because the battery is hidden inside there. We have pulled our cable through the box. We will take the lid off our battery and what we will do next is wire our wire to go to the positive terminal on the battery. We are going to take a simple butt connector and just screw that on the end of the wire and just crimp on the extension. We will connect to our positive terminal now. Lets put our cap back on. We will actually run our ground wire to this bolt that we used to mount our battery box to. We have got our jack wired up. Lets install the jack foot itself. Slide it up into the jack. You have got holes in it for the snapper pin right here. Lets put the pin in and snap it into place and we are good to go. Lets give it a shot. It goes down and it goes up. With three little LED lights. With that, that will finish our install of part number BD500185 from Bulldog.

by: Q.S.06/07/2012

Written June 7 2012 First, the E-TRAILER experience gets the EXCELLENT 5-Star rating. From the first contact through delivery, they stayed in touch with me and even answered a product question while the product was in transit. I ordered the Bulldog Power Jack model BD500185 on Friday June 1 2012 and received the product on Tuesday June 5 2012. Thank you e-trailer!!!! Now, for the Bulldog Product review----only a 4-Star rating, but only due to packaging for shipment. The package box from Bulldog was in bad shape when it arrived. Parts of the power jack were sticking through the box. When I opened the box, the power jack head motor was scarred on one side with black marks and there was something loose rattling around in the head of the power motor. The power motor was only protected by a very thin paper foam sheet, similar to the wrapping you would find when you buy a small set of venetian blinds or a pair of shoes! In addition, the plastic bag holding the bolts, washers, etc, was split open and all the contents were scattered in the box. When I gathered all the items, there was a lock washer missing and I found that when I took the power motor cover off, it was this lock washer that had gotten into the motor head and was rattling around. After seeing the bad packaging, I temporarily hooked up the power jack to make sure it worked. It still worked and the light also came on, and I was able to clean most of the black marks from the side of the power head cover, so I reluctantly installed it on my trailer. It works just fine, so far, and it is fairly quiet. The light is really weak but it will be better than pitch black darkness. Here are some suggestions for the Manufacturer of this model of Bulldog Power Jack: 1) Use better packaging to protect your product!!!! Think PRIDE in product and then there can be PRIDE in ownership! 2) Add a picture in the Installation Instructions showing the proper sequence of placing the bolts, nuts, lock washers and star washers because the written instructions are not clear. 3) Add just two feet to the wire lead going to the battery and I think you will better accommodate more trailers without having to splice the wire. Installation must stop to go buy more wire to add to the existing 4 feet. Two extra feet of wire just can’t cost that much more and you would have much happier customers! 4) Also, include the $0.10 battery post connector. An additional frustration to go buy that as well. 5) Build these in the USA! Disappointed to find out these are “Built in China.” The items I like about your product: 1) The 5 Year Warranty 2) The fact that there is not a “special” wrench to keep up with to manually crank the jack in case of power loss. It only needs a ¾” socket to perform this task, very nice! 3) The level provided on top is a really nice feature 4) The 10” jack foot extension included with the product 5) The lynch pin has a thumb assist that makes using the extension and pin very easy 6) There appears to be a nice rubber seal covering the manual crank access that hopefully will keep out the weather Sorry I cannot address longevity of the product yet but I hope this initial review will help someone else! 43223


Is this jack US made? If not, which one is? It really matters Thanks!

This Bulldog jack is not made in the US. We do have two powered jacks that are US made from Atwood, an Elkhart, IN company. Part 80515 and part AT80718 are linked below.

delivery was within 3 days. awesome. unit is very strong and seems to be built solid. unit is ground to itself so when you bolt to trailer it is already grounded. no need to run an additional ground. mounted in 15 minutes. no hardware comes with unit. washers were not on stock jack so i had to purchase washers. would like to see hardware included ohterwise very good purchase. the drop leg is great. units with out will require more time to retract and extend. very nice. 45212

Very happy with product so far. Light isn't great but then I never use it to begin with. My biggest complaint and only reason I couldn't give it the highest rating is that the wire isn't long enough. Saw a similar complaint so was was ready for it to be an issue. I ended up connecting this unit to the existing the power line from the old power jack. I could have used an additional 10 inches of wire. 45447

Prompt delivery and all was well with the package.install was straight forward. I used the machine screws from my old jack Instead of the included bolts and nuts. My only issue with the Device was the length of the wire. Another 24 inches would Have been nice. When I need anything else for my trailer, I'll Look here first. The delivery trace is a very nice feature!_ 106372

I love this electric tongue jack. I have seen other brands in action -- none compare. This jack is extremely quiet and powerful. The foot that extends from inside the jack is very convenient. The ability to turn the jack 90 degrees for mounting is also a great feature. I would definitely buy another one. 182655

  • Can The Bulldog Powered-Drive Trailer Jack # BD500185 be Installed in a 90 Degree Orientation
  • There is no reason why you could not turn the jack at a 90 degree angle to gain more clearance. Due to the configuration of the holes in the mounting flange, you might need to drill new holes in your trailer tongue to mount the jack in that configuration. The motor housing cannot be repositioned on the shaft. Bulldog tells me that the edge of the motor housing is 1 inch away from the side of the jack tube, as shown in the photo I edited for you.

You can protect the jack from moisture with the part # UF38-944020.

Going higher than that will not benefit you at all since the internal breaker on this jack is rated for 35-amps. You are likely blowing fuses because, when this jack is under a load, it can pull around 30 amps. If a 35 amp fuse continues to blow, then I would suspect a short somewhere on the power wire. You will want to check for any sections that are pinched,...
