Video Transcript for Rebuilding a Bulldog 12000-lb Capacity Jack

Today we're going to be taking a look at the rebuild process of the bulldog square 10,000 pound lift, 12,000 pound static capacity jacks. Now these you'll most often see on the front of very large utility trailers and even some fifth wheel campers. There are several kits available to help you along with your rebuild process. Here we'll have our internal screw, thrust washer, bearing, and pens. This is part number BD500217. Just the bearing itself is part number BD001015.

And we're also gonna have our gear, bushing, and spring replacement kit. Now that gear kit is part number BD500212. There are also two types of handles available, one being the vertical, which you see here. This part number is BD015181. We also have a horizontal option available, I'll explain to you the difference in those in just a minute. That part number is BD800090. The first thing we need to do is remove the cap located here on top.

That's gonna be a five sixteenths inch socket or bit driver. So it's just gonna come out, and we'll have one of those on each side. Once we pull that off, you'll see inside we're gonna have a lot of grease and hidden in there will be a few gears. At this point we need to get in here and just get this grease out. We're gonna be replacing it.

You just need basically a universal grease, it doesn't have to be anything high-temp or anything like that. Just get as much of it out as we can. It's gonna give us a good look inside. What we'll need to do is slide the spring over just like that, and you see how that pin slides out That's the pin that holds the shaft in place side to side. So we'll remove that and set it aside. It's gonna allow us to pull the shaft out and we'll just kind of compress our spring a little bit, be able to pull that out.

With that out of the way, you see that gear's gonna come out. Set it aside, inside out each outside tube there you're gonna have the bushes. Pull those out. Then the main gear on the bottom, we should just be able to lift straight up on that and we can remove it. You also see the pin for that right below it. And here we'll see washer, we can take out. Now that's gonna be all the components that're in the gear and spring kit, so if that's all you need to replace, you just put those back in at this point and your job's gonna be done. If you need to go further that, if you need to get to the bearing or if you need to get to the screw, now we need to separate the outer tube from the inner tube of our jack. So lift up on that, it's gonna give us access here. Here you see the bearing, again that's the part that is available individually or as the entire screw kit, so we'll set that aside. Here's our thrust bearing, now our pins. These are just gonna slide out by hand. All of this comes apart really without too many tools. And at that point, we're able to lift that screw mechanism right up and out. Now we would bring in a replacement, as you would see put a little bit of grease on it, our replacement would drop right down in. Then we'll need to place our pins back in. Then you can take your replacement thrust bush and put that down on there, our bearing's gonna sit on top. Now it's important to position the bearing so that this opening is facing downward. That's gonna help protect it from any moisture and help any rain that might get in there run off. Once we've got this in place, it's time to put our outer tube right back on. And as we do it, we'll see the screw come through the top. Now your washer that you took off the bottom of the other thrust bearing, that goes on. Now the larger of the pins that're included in the gear and spring kit needs to slide through the whole that we've got in the top of the screw. You just kind of want to center that on your screw and then you'll be positioning your large gear right down on top of that. You want that pin to sit in those two slots. Now we'll be bringing the handle bushings through each side just like that. Now our gear for this side is gonna sit down in there, gonna make sure those teeth line up. And then we need to slide in the crossbar where the main handle is. And you just want to make sure the hole, see that smaller hole It's gonna be offset to one side. Make sure that's on the same side as your gear. Now before this fully passes through, we want to get our spring in place, so you bring your new spring in. And we need to kind of get that compressed so it'll slide over the end of that gear and then line up with our handle bushing on the other side. Then we just push this clear through. Now if we compress our spring, we just want to line up that hole with the hole in our gear, place our pin in, and then you see how that spring kind of goes along that bottom side All we'll have to do is push this down until the top side clicks in. Just like that. And you can see at that point, we're back fully operational, it's just time to fill this up with some grease. Now you can do that now since you have access, or you also have the two grease circs on the side, definitely recommend doing it beforehand though. Now we'll just take again a little bit of all-purpose grease, this is a high-temp grease, it doesn't have to be. Want to make sure we get plenty in our gears there. The good news is, you're not gonna be able to over grease it so get plenty in there and that should keep everything lubricated. At this point, we can put our cap back on. Now depending on your situation, you may have a pair of these with a bar running between. You'll want to put your bar on going over to the slave jack. We do have two different handle replacements available. This one's a vertical handle replacement, which means the connection point here is gonna be vertical. It's gonna be up and down. So to replace the handle, that's gonna be placed on there. So we've got a bolt with a flat washer, we want to slide that through. Flat washer on the other side, and then this lock nut, you just want to get it down so it makes contact with the outside. So that's gonna allow us to rotate our jack up and down, and then to store it, since what happens is you're gonna pull out and then allow that to rotate down. Now a vertical handle position is going to allow us to bring the handle over to the front side of our jack, and we can use a handle keeper part number BD500312. You can weld it on. Now if you want this to be on the side of the jack rather than in front, we need to switch over to the horizontal handle. Instead of these begin up and down, they're gonna be side to side which would then allow us to tuck our handle alongside of the jack. And that'll complete our rebuild of the bulldog 10,000 pound lift capacity jack. We hope this'll show you that with just a few parts and a few tools, you can rebuild your bulldog jack rather than having to do a complete replacement.

Replacement Sidewind Handle for Bulldog Heavy-Duty Trailer Jacks - 13-1/2" Radius - Black - BD015181

Average Customer Rating:  4.9 out of 5 stars   (42 Customer Reviews)

Replaces the crank handle for your Bulldog 180 Series, heavy-duty, square-tube trailer jack. Includes a vertical clevis for installing on sidewind jacks. Extends 17-1/2" from your Bulldog trailer jack.


It's a crank handle. No biggie, but even mundane products deserve great customer service and etrailer provides it. During a recent trip we dragged the horse trailer into several truck stops hoping to get a replacement for the rusted mess we'd been using for too long and were disappointed that none were available. From the couch at home a few clicks found what we were looking for and the box materialized on the front porch just a few days later. Thanks!


Perfect fit.


Great Jack but hard to get it to catch the latch when taking trailer off.


Very strong



Fantastic! I remove the handle after use to keep it from “walking off”!


Works great. I used it on a Holland landing gear. The handle where your hand goes is a little longer than the original which helps gripping it.

  • Replacement Sidewind Crank Assembly for Gooseneck Trailer Jack
    We do have a large selection of replacement crank handles for sidewind trailer jacks available. The best way to pick out a replacement will be to determine the manufacturer or model of your existing trailer jack. I have attached a link that will take you to our available selection of replacement cranks that you can look through. You can use the facets on the left side of the page to filter through different manufacturers. For example, the Bulldog Sidewind Jack Crank Assembly # BD015181...

  • Measurements on Replacement Bulldog Sidewind Jack Crank Assembly BD015181
    When looking at Replacement Bulldog Sidewind Jack Crank Assembly # BD015181 the radius measurement, 13-1/2 inches, is half of the diameter of the circle the handle would make when turning the crank. So basically it is a measurement from where it mounts down to the edge of the handle. I made a picture to clarify. The length is how far out the handle sticks from where it mounts to the end of the handle; in this case 17-1/2 inches. If you know the model number of your jack let me know and...

  • Recommmended Landing Gear Jack Crank Handle for 2008 Pace American Enclosed Car Hauler
    Thanks for your picture. Sounds like you have a Bulldog Sidewind Landing Gear and although we cannot be for sure that this is a Bulldog 2-Speed Landing Gear, I can tell you that when I researched your Pace American Trailer it typically is outfitted with a 2-speed landing gear. Without knowing the exact model you have, my best recommendation is the vertical clevis crank # BD015181. the horizontal clevis crank # BD800090, or you may need something more heavy duty.

  • Recommendations for Jacking Up a Trailer with Bulldog Landing Gear Jacks on Uneven Terrain
    Bulldog does not offer a pivoting foot plate that would install onto the Bulldog Square Jack # BD182700. The best recommendation I could give would be to wait till you are on level ground to jack your trailer up and to make sure you have the wheels of the trailer chocked with something like the part # HT38511. A large block of wood could help as well. You might also be interested in a crank for this jack like part # BD015181.

  • Replacement Trailer Jack for 10 Foot Moritz Dump Trailer
    The Bulldog # BD182701 that you chose would likely work well for you, but I have a feeling the jack has WAY more capacity than you need. The capacity of the jack only needs to exceed the fully loaded tongue weight of the trailer, not the GTW gross trailer weight, which is the total weight of the trailer plus its contents. I don't know the GTW of your trailer, but from what I saw online, think you could probably get by with a smaller capacity jack. The Bulldog # BD182701 jack doesn't include...

    There are two options for a replacement for your Bulldog jack.

The second option is a vertical handle, Replacement Bulldog Sidewind Jack Crank Assembly w/ Vertical Clevis - 13-1/2" Radius - Black # BD015181. Either one will work, it will just depend on which one works best for you.

    The Bulldog Square 25K Drop-Leg Jack, part # BD182701, can be welded to your trailer on any of its four sides if installed in a direct-weld application. My technical contact at Bulldog confirmed that the 4-inch outer tube is suitable for welding on any side and in any preferred orientation. Before welding you will want to confirm that you have proper clearance relative to other components on your trailer and that you will have enough room to operate the crank handle. All welding must...

  • Replacement for Fulton 12K Magnum Series HD Jack
    The photos you attached did not come through but in order to replace your Fulton 12K Magnum Series HD Jack, I recommend using the Bulldog Square Jack part # BD182701 which has a 12,500 lbs capacity and offers up to 12-1/2" of lift. Unfortunately, Bulldog does not offer the extension rod that will allow you to operate the jack from the side of the trailer as they will vary depending on the trailer.

    I have a replacement jack option for you, I reached out to my contact at Fulton and the Fulton Magnum Series 12000lb got discontinued a few years back, and all of the rebuild kits and replacement parts were discontinued with it. The only option is going to be to replace the jack completely. I recommend the Bulldog Square Jack - Drop Leg w/ Spring Return - Sidewind - 26" Lift - 12,500 lbs # BD182701. You will also need the sidewind crank # BD015181. I included a few videos of the # BD182701...

    I had one of the Bulldog Square Jack - Drop Leg w/ Spring Return - Sidewind - 26" Lift - 12,500 lbs # BD182701 checked and it takes just about 8.5 revolutions to raise an inch. This does not include the handle, however, so you may need to add the Replacement Bulldog Sidewind Jack Crank Assembly w/ Vertical Clevis - 13-1/2" Radius # BD015181 if you plan on using it as a standalone jack.

  • Recommend 10K lb, 2 Speed Crank, Weld-Mount Bulldog Jack For Gooseneck Trailer
    I contacted our representative at Bulldog, the item you selected, Bulldog Trailer Jack, part # BD183902, would be the correct jack you are looking for. The Bulldog Jack # BD183902 is a 10,000 lb capacity, spring loaded, 2 speed jack that is welded to the trailer. In addition to part # BD183902, you will need the Bulldog Sidewind Jack Crank Assembly, part # BD015181. I would recommend having a qualified welder install the Bulldog Trailer Jack # BD183902 on your gooseneck trailer.

  • 10k Gooseneck Trailer Jack Recommendation with Handle and Non-Spring Return

  • Recommendation for a Tandem Jack Setup on a 20k GVW Dump Trailer
    The Bulldog 2-speed jack # BD183816, that you referenced would work well as a jack in a tandem setup for you. Each of these jacks is rated for 12000lbs, so they would work well on your dump trailer that has a 20000lb GVW. I spoke with my contact at Bulldog about whether or not you can use the 2-speed function of this jack when used in tandem and he said that you will be limited to only one gear when jacks are used in tandem.

  • Replacement Jack Handle With Vertical Clevis for Gooseneck Trailer Jack
    The Bulldog Replacement Sidewind Jack Crank Assembly # BD015181 that you referenced does have the vertical clevis you indicate was on your original.

If you can provide the brand and part number from your jack tube I'll be glad to confirm the correct replacement handle for you.

  • Is A 2-Speed Jack Easier To Crank Than A Single-Speed For Grain Cart With 6500 LB Tongue Weight
    The benefit of the two-speed jack like part # BD183750, would be the speed at which you can turn the handle. When using the low gear the jack will lift 1 inch every 29-1/2 turns. When used in high gear it will lift 1 inch every 9 turns. Although it may be a bit easier to turn in low gear, you would have to crank the handle more than three time as much to lift the same height. The Bulldog Square Jack, part # BD182701, you referenced, has a lift capacity of 12500 lbs and a static weight...

  • 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.

  • Is There an Extension for Replacement Sidewind Handle for Bulldog Heavy-Duty Trailer Jacks
    In regards to the Bulldog Square Jacks like part # BD182805, we don't offer any sort of handle extensions so you'll have to get under the trailer to use the Sidewind Handle for Bulldog Heavy-Duty Trailer Jacks part # BD015181 or fabricate some sort of extension of your own. That said, you could convert to electric using the Bulldog Powered-Drive Kit part # BD1824200100 and this would allow you to operate the jack without being directly under the trailer and it's much easier to operate.
