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.

I had a 12000 # bull dog jack that striped the nut. Not wanting to buy a new jack I searched all over for parts to the point of calling cequent performance parts. They informed they could not sell to me but helped me find what part # needed and instructed me to go to etrailer and put the part # in. I found the site put my part # in and the screw and nut kit popped up instantly. I made my order with no problems and received an email shortly after of my order letting me know that they received it. Another email after it shipped and one more upon delivery. The part was more than needed because they would not just sell the nut, I had to buy the whole kit. The directions were not helpful at all, but it was an easy removal of the old screw and the new part was a perfect match and they provided new pins spacers and a bearing. The whole removal and replacement of the screw and nut kit took about an hour and was straight forward once I tore into it. I was pleased with every thing and I will use etrailer again for all my parts in the future. 206062

I used this bulldog jack screw kit to repair a similar design stallion trailer jack which is no longer produced and parts are unavailable. It worked great and seems to be of good quality. This was around a year ago, it gets used regularly and it still is working great. 425767

Great replacement with new pins, cheaper and faster than replacing with a new jack. Glad parts are available for these rather than having to cut off old and weld on new and throwing away old jack. Repaired in about 20 mins. 37027

Do you have a question about this Accessories and Part?


  • Are There Replacement Parts for my Frozen 12,000 lb Gooseneck Bulldog Jack
  • The gooseneck trailer jacks are repairable. It is hard to say exactly what is wrong with your jack and how difficult it would be to repair, but we sell replacement parts that could fix your jack. We sell a Replacement Screw and Nut Kit, part # BD500217, as well as the Replacement Bulldog Sidewind Gear, part # BD500212, that you referenced. I would recommend that you take yours off and take it apart carefully and see if you can find what is causing the jack to be frozen and then replace...

  • Can The Bulldog Square Jack, # BD182500, Be Rebuilt And Are Replacement Parts Available
  • We do sell replacement parts for the Bulldog Square Jack - Fixed Leg - Sidewind, # BD182500. We have the Bulldog Replacement Sidewind Gears, # BD500212, which are the gears located at the top of the jack that the sidewind crank would be connected to. We have a replacement nut and screw repair kit that is for the nut and screw that is located at the bottom of the jack. This is the screw that will raise and lower the leg. The available kit is for jacks manufactured after 2003. The part...

  • Replacement Screw and Nut for Bulldog 10K / 12K Square Trailer Jack
  • The screw and nut assembly, # BD500250, fits Bulldog jacks rated at 10,000 lb lift and 12,000 lb support. We also have kit, # BD500217, which is designed to fit Bulldog series 182 jacks from 2003 to present with a 12,000 lb capacity. I have included a picture to give you the dimensions of each product.

  • Bulldog Jack Gear Compatibility With Stallion Brand Jack And Electric Conversion Kit
  • The Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100 will allow a single speed jack with 12K capacity to become a powered drive jack. The Replacement Gear Kit for Bulldog Sidewind Jacks w/ 12,000-lb Capacity # BD500212 may work with your Stallion brand spring loaded drop leg jack, but I can't confirm it will work without replacing the screw and nut kit # BD500217. I know customers have changed this screw and nut assembly on a stallion jack without...

  • Replacement Parts for Bulldog Square Jack
  • The replacement parts we have for the Bulldog Square Jack # BD182500 are a Replacement Gear Kit # BD500212 and a Replacement Screw and Nut Kit # BD500217. These are the two most likely aspects of the jack to be causing your problem. I have attached the only two diagrams we have related to this trailer jack. The inner tube is held to the outer tube by the screw and nut assembly.

  • Replacement Parts For 12,000 lb Jack
  • We don't have any Trailer Tough brand jacks, however, the Replacement Screw and Nut Kit for 12000-lb Capacity Bulldog Jacks, # BD500217 may work. If you trade out the gears # BD500212 and bearing # BD001015, you will basically have a new jack on the inside. You could also just replace the entire jack with the Bulldog Side Wind Jack Assembly - 12,000 lbs # BD182513, however this jack does not have a drop leg. If you want the hand crank you will need # BD015181.

  • Troubleshooting Bulldog Electric Landing Gear that Turns But Does Not Raise or Lower Jack
  • It sounds like you broke a bevel gear in your # BD1824200100 by over extending it and that is why everything seems to be moving but the jack does not go up or down. When you bought this jack set it came with an extra bevel gear so as long as you still have that you can try inspecting the current one and replacing as necessary. To access the gears inside of the heavy-duty Bulldog jacks you simply remove the screws that are holding on the plate covering the top of the jack. Once that...

  • Replacement Nut and Screws for a Bulldog Landing Gear Jack
  • The replacement nut and screw kit you would need for your Bulldog jack will depend on which jack you have. If you have a 10k jack like the part # BD182500 you referenced you would want the part # BD500250. If you happen to have the 45k capacity landing gear like part # BD500153 you would want the part # BD500293. If you have a 12k jack like the part # BD182500 you would want the part # BD500217.

  • Replacement Nut and Screw for 4 Inch Square Bulldog Jack on a Gooseneck Trailer
  • Nut is the term used for that threaded collar inside the jack. And the screw would be the other part. The nut is not available by itself but you can get it with the screw (not a bad idea since there could be damage to the screw as well). If you have a 12K capacity Bulldog jack, 182 series, from 2003 to present then you would use # BD500217. If it is rated for 10K lift and 12K support then you would use # BD500250.

We also offer Item # BD500217, which is designed for use with Bulldog series 182 jacks from 2003 to current with 12,000-lb capacities. It also has a diameter of 1-1/4 inches.

  • How to Access the Gears for the Heavy-Duty 12000 lb Bulldog Jacks
  • To access the gears inside of the heavy-duty Bulldog jacks, like part # BD182415, you simply remove the screws that are holding on the plate covering the top of the jack. Once that plate is removed, the gears, pins and handle should be exposed. We also offer the Replacement Screw and Nut Kit, # BD500217, for the heavy-duty 12,000 lb capacity Bulldog jacks. I have attached two photos that show the inner workings of the heavy-duty Bulldog jacks for you to check out. The cross shaft...

  • Replacement Internal Screw Availability for Bulldog Jacks
  • It's hard to say what would be the correct replacement nut and screw for your jack since I do not know what brand or part number you have. But if you have a Bulldog 10k Jack you would want the part # BD500250 and if you have a 12k Bulldog Jack you would want the part # BD500217. Currently these are the only two we carry.

  • Replacement Nut and Screw for a Bulldog 10K or 12K Capacity Landing Gear Trailer Jack
  • The nut by itself is not available as a separate part but we do have the screw and nut assembly, # BD500250. It is designed just like you have said with the 2 roll pins and is rated for 10K lift and 12K static load. We also have # BD500217. It is designed to fit Bulldog series 182 jacks from 2003 to present, with 12K capacity.

  • Fulton Equivalent for Replacement Screw and Nut Kit # BD500217
  • We may be able to help you find the replacement parts you need for your 12K-rated Fulton jack but a part number for the jack and a photo would help. I did check all 12K-rated jacks and landing gear that we carry and none is the Fulton brand. I did link for you a photo of the part you referenced to show its dimensions.

  • Dimensions of the Replacement Screw and Nut Kit for 12000-lb Capacity Bulldog Jacks
  • A specific dimensional drawing of the replacement screw and nut # BD500217 is not available for proprietary reasons. I can tell you that the diameter of the threaded parts is 1-1/4 inches. It was specifically designed for 12K Bulldog jacks, series 182, from 2003 to the current generation. I did include a picture that contains measurements we took here that might help you.

  • Handles Hard to Turn on Bulldog Jacks Installed on a Dock Ramp
  • It sounds like there may be a corrosion issue forming since the Bulldog jacks are in a marine environment. Some jacks have an external grease zerk so you would want to pump some grease in them with a grease gun like # L30132, to push out the old grease. If your jacks do not have grease zerks then you will need to open up the jacks and look inside to determine if the grease is old, if there is corrosion, or if there is something inside that is gumming up the works. If the jacks are ever...

  • Recommended Landing Gear for Hillsboro 300 Gooseneck Trailer
  • On your 1998 24K Hillsboro 300 gooseneck trailer, the Stallion Landing gear is not a brand I'm familiar with. The Replacement Screw and Nut Kit for 12000-lb Capacity Bulldog Jacks # BD500217 is not welded in and has a 2 inch by 2-3/4 inch nut on a threaded 1.25 inch diameter screw. Because you say the nut may be welded, I recommend changing out the jacks completely with the Bulldog Square Jack - Drop Leg w/ Spring Return - Sidewind - 12-1/2" Lift - 10,000 lbs # BD182800 or if you...

  • Bulldog Powered Drive Landing Gear Stops Lifting and Trips Circuit Breaker
  • You may need to lubricate the jack legs. Over time the grease inside can wear down and that can lead to difficult operation, corrosion and grime build up, making it harder for the motor to work. On the Bulldog jacks there are locations for grease below the connecting rod between the jacks. There are also locations to oil, not grease, the connecting rod. These locations are on either side of each jack leg where the rod goes into each leg/exits each leg. If you continue to have problems...
