Video Transcript for Rebuilding Bulldog Sidewind Jacks

Today we're gonna be taking a look at the rebuild process for the Bulldog 2000 pound capacity round trailer jacks. What we're looking for is the side wind style. These are gonna be the 150 series jacks, and pretty simple process for re-building the jack. Depending on your needs, you'll need 3 different parts. We've got our replacement cap here. This is part number BD015500.

You may or may not need this if yours is undamaged, but it is important to keep dirt and debris from getting in the top of your jack. We've got our replacement handle and gear kit. This is gonna have just about everything that we're gonna need to rebuild the jack. You can see we've got our bevel gears here, we've got the flanged bushings that fit on the outside tube of the jack, we've got the pressure bushing there, the pins, and some washers. Also got our handle. This is gonna take care of the complete upper end of the jack.

Now once we get below this bottom gear, there's a bushing that is inside of the jack that's our friction reducer. It's a good idea once you get to that point, go ahead and switch out the bearing. The gear kit with the handle, everything over here, is gonna be BD500256. Then the bushing in addition BD500251. Let's get these moved over to the side.

We'll start taking this jack apart. For the flat blade screwdriver, we'll just want to remove the cap if it still is on your jack. Inside here you'll see it's pretty greasy. We're gonna go ahead and wipe out all of that that we can. Now we'll turn our jack to where you'll see that little half moon cut out that's in our gear. Our pin's gonna be right in behind there. We take a five 32nd punch.

We're gonna get that driven on through. Once we get it most of the way through, we're gonna have to angle our handle a little bit to get enough room to come completely out. We'll lift up on our handle once that's through. Easy to slide out. You can see that's gonna be a direct replacement of it. We've got five and three-quarters of an inch in total handle length here. That gives us good leverage. See once your handle comes out, your gear is just gonna drop down. Again, these gears are universal, so the bottom gear fits the side, the side gear fits the bottom. We don't want to forget the pin for our handle. You can see the pin that goes in the handle. That's gonna have the little grooves in it, whereas the pin for our base gear is going to be solid. It's not going to have any grooving in it. The base gear's just gonna slide off, and there's also a floating pin which goes through that middle section, which is this screw, so we can take that out. Right below it's that thicker black washer. This is gonna act as a support washer for our gear inside. Then we can just tap out the square portion there. That's that flanged bushing. It's gonna fit right over there in the square hole. That just gives our handle a much wider area to ride on so it's not riding on just the thin tube of the jack there. All right, now it's time to pull on the base, or we can just lift up on the outer tube, and inside we've got our bearing and our other support washer you see there. That's gonna fit right down on top of the screw, and our bearing fits on there. It's gonna offer us a very, very low-friction operation. You'll see the screw just threads down into that baseplate, so as we turn it, this expands, running the jack down. We go the other way, it's gonna bring our jack back up. This screw is very, very hard to damage, so if your jack isn't operating properly, it probably has to do with this bushing creating friction, or the gears not meshing together anymore. This is gonna be exactly how you'd go through the process of re-building it. We'll have our new bearing in place and the support washer that comes with it. Now we can bring our jack outer tube down on the inner tube here. Want to align that elongated dimple with the groove. Bring that all the way down, and then our screw's gonna come right back through this hole that's in the top of it. At this point, we're gonna put our washer back in place. This is that larger black support washer. We've got our base pin. It's gonna slide through. Now we want that to be about equal on both sides. You can see it's about equal and how much is hanging out on each side of our screw, and in your case you're gonna grab your new pieces as you put this back together. This is a brand new jack. We're just taking it apart so we can get a good look at it, so we're gonna reuse our old stuff. Get my gear, and we want to be sure that our pin sits in the enclosed slot, not the open slot. All right, and that should sit down so that the top of the gear is almost dead flush with the top of the screw. flanged bushing will go back in. Might offer a little resistance, but nothing too crazy. Then we'll take our other gear, and again, these are universal. It doesn't matter which one you use for which slot. Gonna place that in so that the gears line up. They're gonna mesh together. Then our handle's gonna come up through the bushing. It's gonna come through the gear, and right out the other side there. You'll see the hole in the handle. We want to rotate our gears so that that half moon opening lines up with the hole. Place the pin that has the little grooves in it right in between that bushing and the gear in that opening. Slide it in, and then we need to cap it in far enough so it's not gonna offer any interference. It should be just inset to the gear. Right back together. Now we want to use a good quality grease. It doesn't have to be a high-temp grease or anything like that, and we're gonna go in there and make sure we get this fully lubricated. You see, right back to brand new there. We'll have a great, smooth operation that's gonna make our trailer very easy to lift and lower with all of our new components in there and fresh grease. Now the replacement cap. You'll see it's got a little bit of a notch right there in the grooves. I like to line that up with the notch that's in the tube of the jack itself. That's just gonna tap on pretty quick and easy. That's gonna complete our rebuild of the Bulldog 150 series jacks. As you can see, with a few parts, and a few tools, you can really save yourself a lot of money as opposed to buying a brand new jack.

Thank you, fit and operated perfect


the part fit and is working fine. will use parts again when needed


I have 2005 Vanguard boat trailer. I have no info on the trailer or the welded tongue jack, I have looked all over for a rebuild kit for the jack but was told they couldn't help. I found ETRAILER and they where able to help me. I rebuilt the jack for under $50. They where fast at getting the parts shipped to me, l will always check ETRAILER first when i need parts for my trailer.


Exactly the right part I needed! I have two bulldog jacks welded to front of the gangway of a floating dock that has to be at least 10 years old and this handle worked perfectly to replace one of the handles that finally broke.


We needed a replacement handle for a Bulldog Jack. We called customer service. They were helpful, friendly, and quickly got us the replacement handle we needed. Thanks.


The handle was ship on time and arrived at the time stated. I seams to be as good as the original handle.

Product as listed. Exactly replaced the handle our crew managed to lose. Delivery was quick and product arrived well packaged. Saved us from having to replace the entire jack. Thanks.


Tyhe handle is easy to replace on the jack. Well worth the cost of replacing the handle than the whole jack.


Product itself is as advertised.
good; all parts that were supposed to be there, were there.
Delivery time was on the money. No problems whatsoever.


The part works great and was easy to install.
It seemed to take longer to get to me then I'm used to with etrailer. Hope it's a one time thing.


The person I talked with on the phone was very knowledgeable and helpful. I received the parts quickly and they were just what I needed. I would order again.

The jack is still working well, haven’t had any further trouble. Thanks for the follow up.
Mike T - 12/29/2017


Smooth transaction, pleasure to deal with, highly recommend, would buy from again, arrived quickly and safely, just as described


Customer service was very helpful. Sent picture of product I needed and rep was quick to respond and give me the information I needed to order the part.


Just what we needed. Shipped and delivered very fast. The manufacturer referred me to you because they don’t sell anything direct to consumer. I will definitely order from you guys again


Handle looks like the one I need but I haven't put it on yet. The item was shipped in a good timely manner!!


Perfect fit, and was just what I needed for my Jack.


Very good product delivered in a timely fashion and worked perfectly for the repairs.

  • Should a Bulldog Series 190 Sidewind Jack that is Not Working be Repaired or Replaced
    There can be many reasons a trailer jack might bind and cause the center pin to be sheared off from the handle. The more common causes is if the jack is overloaded, if the lower inner tube is bent, or if debris has gotten into the gears or bearing. To determine if you can just replace the inner parts and use your existing jack, you will want to inspect the whole jack to make sure everything is structurally sound and the lower tube is not bent. If the lower tube is bent I would recommend...

  • Replacement Crank Handle for Atwood Trailer Jack to Provide Better Tailgate Clearance
    Sometimes a substitute part like a jack handle will fit on another brand of jack but we do not test items in this way since there are so many possible combinations. I did check the dimensions of an alternate handle, part # BD500171, and found that the shaft diameter on both is 3/8-inch. This handle does have a larger radius, 9-1/2-inches instead of 6-1/2 for the # AT25526. Odds are good it will fit the jack. But if you want the sure thing just replace the A-frame jack with a side-frame-mount...
