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.

Perfect fit. Very pleased with the service and fast delivery. The trailer we needed repaired is ready to haul again.Thanks, I've found a new supplier fir trailer parts. Will also be recommending you to all my friends and the local business that couldn't locate the parts we needed. thanks again.?? 589192

This was easy to put in & was perfect match. I think I broke the other one by unloading the machines on the trailer without being hooked up to the truck. The trailer goes up in the front when you do this . Once the machine is off , trailer slams down on the jack stand hard. Live & learn! 706472

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

Hello I buy things online all the time this was my first time buying from you and the experience was great . The break in shipping was excellent cuz I didn’t like the 5-7 business days to start and the automatic upgrade was nice 477356

If you have a pro series 12k jack. Buy the bulldog insides and drill the top hole to 3/4 inch in the top of the tube. All bulldog parts will work and can buy unlike the pro series Part numbers-> BD500217 BD500212 457427

These parts were a great time and money saver. The tongue jack on this trailer was welded to the trailer cross member by the trailer manufacture, so removing the old jack and welding on a new one was going to be expensive and time consuming; plus the trailer would be out of service for a couple of weeks. With the parts to rebuild the jack, we did the repair in less than two hours. As a bonus, the parts actually arrived two days sooner than promised. Thank you etrailer.com for the great service. 482744

Went to drop my gooseneck horse trailer after use and no-go! Apparently the screw jack became stripped over the years and needed to be replaced. The hardest thing about this project was removing the entire unit from beneath as shown in the pictures. For clearance I had to not only drive the rear wheels onto small ramps but also dig beneath the jack to drop everything out. Everything fit perfectly. The video was great at explaining things. Brendan gave me a few shipping options and items arrived promptly without breaking the bank. 697292

Build quality is outstanding, customer service top notch. My only issue was that the replacement threaded rod diameter was significantly larger than the ones being removed. Etrailer has an outstanding measurement page, I just did not do my due diligence. I just turned the shaft diameter down a bit and now I have heavier duty rod and nut in my landing gear of my gooseneck. I am very happy with that. 765364

Excellent customer service. Hally spent time on the phone with me to answer questions the web page didn't. She even went to one of her techs to get me the info. She could have easily put me off but didn't. She was pleasant and was genuinely interested in helping me. I haven't installed the screw and nut yet but after inspection all dimensions are exact and I have no doubt the parts will fit my trailer. I will do business with etrailer.com again! Ron D.

  • 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.

  • Troubleshooting Bulldog 12,000 lb Jack for Replacement Parts Needed

  • Replacement Screw for Trailer Jack with 1-1/4 Inch Diameter
    The Ram Trailer Jacks generally use a 1" diameter threaded rod whereas the Bulldog Trailer Jacks generally use a 1-1/4" threaded rod. Therefore, it would appear as if you have a Bulldog Trailer Jack and in which case the Replacement Screw and Nut Kit part # BD500217 at 17" long x 1-1/4" diameter most closely resembles the Replacement Rod and Nut Kit part # TJD-12000-RODNUT that you were looking at so it may be what you need.

    If your trailer has 12k capacity Bulldog brand jacks then yes, the part # BD500217 would be the correct part you'd need. If instead they are Bulldog 10k jacks you'd want the part # BD500250 instead.

    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 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.

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.

  • 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.
