Video Transcript for Bulldog 5000lb Jack Rebulid

Today, we're going to be taking a look at the rebuild process on the Bulldog 5000-lb capacity jacks. These are typically considered to be the 170 series jack. You're going to have the square top with the metal cap. This is going to be a side-wind configuration. They've got excellent replacement part solutions available regardless of whether you've messed up your handle, the bearing or the gear set to allow you to completely rebuild this jack without having to replace it. It's a really nice, straightforward process.

The gears are going to be part #BD500106. Gives us our base gear. Gives us our handle gear. It's going to give us the pin for our handle and the pin for our base gear. That's a nice, straightforward setup. We're also going to have our bearing with thrust washer.

This is going to be part #BB500223. You'll see that's going to be a shielded bearing, so if water wants to enter the top of the jack, that shields it, takes it around it. You can see the bottom. That's designed to rotate. As we operate our jack, that's going to give us a very, very smooth, friction-free operation.

We also have a handle replacement part number. This is Part #BB500105. This is going to be a direct replacement. It's got that bell-shaped handle. It's a very comfortable handle.

It's going to give you the bushings that go in each side of the jack, and it's also going to give us the pin there. Let's get our parts set aside. Of course, we're rebuilding a brand new jack here, so we're just going to reuse the parts that we take out. We'll start by removing our cap here on top. We've got an 11mm socket. We just want to take both of these lock nuts off. You don't have to worry about holding the other side. These are carriage bolts. Once those are off, take out our two pins. Pull off our cap there. This typically doesn't get damaged, but in case it does, we also have that available on our website. The part number you'll need to replace this is BD500205. Once that is off, you'll see it's going to give us a pretty good look right into that gear set. Want to take a little bit of the grease off of it there. Then, when we put this back together, we are going to fully grease it back up. We just need an all-purpose grease. It doesn't have to be any kind of high-temp this or that. Once we've got most of that out of the way, we're going to see as we turn our gear, it's going to be like a little half-moon shaped cutout. You'll see a pin in there. It's going to go all the way through. That's the pin that we need to remove. That's what's holding our gear and our handle in place. Typically, for this, you'll use a punch. This is a 5/32nds punch. Just start tapping that through. Once we've got that pin driven through, we'll get it set aside. You can see that's going to cause our handle to move pretty freely, so we'll pull that out as we hold on to our gear there. Now, when we remove our side gear, they're both pretty much the same, the top and the bottom gear, but our pin needs to go through the pass-through area for our handle, and it needs to go through the non-pass-through area for the base gear. We'll pull that one off now. You can see that just that little pin that just floats in there. Pull that out, and that's going to match the other pin that came with our gear set. You can also see on each side here, you've got one there and on there are going to be our handle bushings. If you need to replace those, you just tap these out and put your new ones in place. Then we're going to be ready to pull the inner tube of the jack out of the outer tube. You'll see as we do, you'll see the screw start to sink down in there, just like that. We've got our washer there that we're going to hang on to. We'll reuse that. If we continue to pull and separate, there on that underside, we've got our thrust washer there and our bearing that rides on top. You'll see the design of the jack. It's pretty simple. It's just a really large machine-style screw. That's probably never going to give you failure. The typical failure either comes from our bearings, our gears or our handle. That's why they make them readily replaceable, very easy thing for you to do. Once we have that off, we would take our new thrust washer and bearing. We can drop it down on there. I think it's also a good idea to spread a little bit of grease on that screw. Certainly isn't going to hurt anything, let that work its way through. While we've got it out, we might as well just help our bearing out a little bit, throw a little bit of grease in there. Now we're ready to take our outer tube and slide it back on the inner tube. Now there's an indention on the side of the outer tube that we need to line up with the long groove on the inner tube, just like that. We'll bring that on down, see our screw right there on the top, come right through. We'll take our washer. That's going to slide on. We've got our floating pin. Slide that into place. Want to make sure that's about equal amounts hanging out on each side. We'll place that lower gear on. Again, our gears are the same, but we want to be sure we capture that pin inside that closed opening. We'll grab our handle. It's going to come back through. We'll slide our gear in place there so it goes through that. It's going to come all the way through that outside. You can see the opening in our bearing there. We just need to line that up with the hole that's in the handle. Once we've got those aligned, we'll slide our pin back in. You saw it was about flush with the outside of the gear when we took it apart. You can leave it there. I just like to knock it down in to where it's about 50/50. All right. Now we'll cap it off just by sliding our new cap down into position. Re-insert our carriage bolts there. Now, you want the head of these bolts to be on the same side as your handle. That way, you won't have anything sticking out there you might get your fingers stuck on or something like that. Now, we don't have to crush this like crazy or anything. We just want to get those down to where they're snug. That's all there is to it. That's going to complete the rebuild side of it. You'll see the hole that's been drilled all the way through the base here, or that inner tube. This is designed to accept accessories. We have two available. One would be Part #BBCP555. It's going to be the wheel. Nice, heavy-duty wheel. Just simply take that clip off, slide it on to your jack. Slide your clip back through and secure it in place. That's going to help you keep your trailer mobile. It's a nice, larger wheel, so it should roll over things. You'll see it's got good width to it. Also, we've got Part #BD018564. That's going to be a removable foot plate. It uses the same style pin. It will slide right down on there. This is just to help spread or dissipate that energy out over a greater area so we don't have to worry about our inner tube here sinking down into the sand, the mud, the gravel, even the asphalt, things like that. We hope this shows you how with just a few simple tools and a few inexpensive parts, we we're able to completely rebuild our Bulldog jack rather than purchasing a new one.

This replaced my existing thrust bearing on a Shelby made welded on crank tongue jack that the cage has rusted and no longer held the balls. It was the perfect interior I/D and exterior I/D which I was worried about. I had to use some washer to make up some hieght differences, but it worked great in the end! 678414

I was looking for a bushing to repair my jack and some grease for the screw but was not confident of exactly what I needed so I called the toll free number. The customer representative was very helpful and knowledgeable! After getting my address to ship my order, he advised me that the office was fairly close to where I was located and suggested the possibility to save shipping and just picking up the order which was really nice! The order shipped very quickly and was exactly what I was looking for. 469705
