Video Transcript for Rebuilding Bulldog Round Jacks

Today we're going to be taking a look at the rebuild process for the Bulldog 2000 pound lift capacity round trailer jacks. What we're looking for is the side wind style. These are going to be the 150 Series jacks. Pretty simple process for rebuilding 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. Now, this is going to have just about everything that we're going to 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.

Got the pressure bushing there, the pins and some washers. Also got our handle, so this is going to 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 going to be BD500256 and then then the bushing in addition BD500251. Let's get these kind of moved over to the side. We'll start taking this jack apart. With a 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 going to 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 cutout that's in our gear. Our pin is going to be right in behind there. We can take a 5/32 punch. We're going to get that driven on through. Now, once we get it most of the way through we're going to have to angle our handle a little bit to give it enough room to come completely out. We'll lift up on our handle once that's through, it'll usually slide out and see, that's going to be a direct replacement of it. We've got 5 and 3/4 of an inch in total handle length here. That gives us good leverage. Once your handle comes out your gear is just going to drop down. Again, these gears are universal, so the bottom gear fits the side, 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 going to 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 is just going to slide off. Then there's also a floating pin that goes through that middle section which is this screw. We can take that out. Right below it is that thicker black washer. This is going to act as a support washer for our gear inside. Then we can just tap out this square portion there. That's that flanged bushing that's going to fit right over 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. Inside we've got our bearing and our other support washer you see there. That's going to go right down on top of the screw and our bearing fits on there. It's going to offer us very very low friction operation. You'll see this screw just threads down into that base plate, so as we turn it, this expands running the jack down. Go the other way, it's going to 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 because you're creating friction or the gears not meshing together anymore. This is going to be exactly how you'd go through the process of rebuilding it. We 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. We can bring that all the way down and then our screw is going to come right back through the hole that's in the top of it. At this point we're going to put our washer back in place. This is that larger black support washer. We've got our base pin, it's going to slide through. Now, we want that to be about equal on both sides. You can see how it's about equal and how much is hanging out of each side of our screw. In your case you're going to grab your new pieces as you put this back together, but this is a brand new jack. We're just taking it apart so we can get a good look at it, so we're going to reuse our old stuff. From our gear we want to be sure that our pin sits in the enclosed slot, no the open slot. All right, 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. It might offer a little resistance but nothing too crazy. Now, we'll take our other gear, and again these are universal. It doesn't matter which one you use for which spot. We want to place that in so that the gears line up and they're going to mesh together. Then our handle is going to come up through the bushing. It's going to 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 tap it in far enough so it's not going to offer any interference. It should be just inset to the gear. Right back together. Now, we'll want to use a good quality grease. It doesn't have to be a high temp grease or anything like that and we're going to go in there and make sure we get this fully lubricated. We see we're right back to brand new there. We'll have great smooth operation that's going to 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 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 going to tap on pretty quick and easy. That's going to 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.

I used this to repair a jack that I purchased about 20 years ago. The bearing had disintegrated and the screw was frozen with rust and crud. I ordered the repair kit and cleaned the jack up. I installed the new bearing and spacers. It works just like it did when I bought it. Should be good for another 20 years. 672315

After calling Fulton customer service to find the parts for my Jack that was on my Trailrite trailer from 1990. They told me the jack was obsolete and no parts were available for the jack any longer. My boat mechanic told me to check out etrailer. I found the videos helpful in matching up my existing parts with the current products. Found that a combination of Fulton bevel kit for the 800-1200 jack and the Bulldog 2000lb. Bearing kit was what I needed, I did have to use a combination of new and old washers to get the right spacing. 367891

Watching people struggle with worn out tongue jacks, it's amazing to me they don't just replace the bearings. A simple procedure that restores the jack to factory-new operation very inexpensively. 13622
