Today we're going to be showing you the rebuild process on the large, square-style, weld-on, twelve thousand pound jacks. This is part number TJD-12000SP-F2. Typically these jacks are going to be welded on your trailer. The last thing you want to do is cut them off, grind it down, and weld a new one on. Here at Etrailer we have the full assortment of replacement parts. This in particular is the Ram, brand or the Etrailer brand jack.

A few of the different replacement parts that are available are going to be the cap, that's going to fit on top of the jack, keeps out the moisture, keeps out the dirt. This is part number TJD-12000-CP. We also have the gear kit. This is part number TJD-12000-GR. We've got our bearing replacement. This sits in there and reduces the friction so we don't have all of that weight riding metal on metal.

You can see the inside portion of our bearing spins while the outside portion spins freely. This part number is TJD-12000-BR. We're also going to have the return spring. This is going to draw that drop-leg back up. That's what causes it to spring back up.

This is part number TJD-12000-RSP. Even have the clip for the handle. Now, this is going to come unfinished. These need to be welded on in a location of your choice, however you want to store your handle. This is part number TJD-12000-CLIP. We're going to have the replacement shaft.

This is the handle shaft so our handle can connect on either side here. It's also going to come with the bushings that fit in the side of the jack. This is part number TJD-12000-SHABUS. Lastly, we're going to have the replacement handle. This handle can be mounted on either side. It has the vertical clevis. It's part number is TJD-12000-HD. Now, to remove our cap, we've got the two bolts that hold it in place. There's going to be one here, and catty-corner there'll be another one. Small socket, in our case it's going to be an eight-millimeter we're going to use to remove that. Get that one out of the way and do the same thing for the other one. If it's just the cap you're replacing, at this point you'll grab your new cap, and we'll just thread those bolts right into that same location, but go a little bit further into it. The next thing we're going to do is get our handle removed. Now, you really only need to remove the handle if you plan on replacing it. If you don't plan on replacing it, you can get this shaft out without removal. We're going to show you how to replace it, so it's coming off as well. To do that, use a fourteen millimeter. Now, your bolt's not going to be very tight here. You want it to be able to slide, you want the handle to be able to slide in and out there. It's going to be a washer on each side there. Then the handle, just set it to the side. Now, if we look at the internals of our jack, you can see the smaller gear, it's going to fit on the handle shank, or handle shaft. That larger, the base gear, it's going to sit down on the bottom. Now to see what we're doing here, give you a little bit better look, we're going to get all this grease out of here. You want to be sure you've got some grease on hand during your rebuild, so you can get it replaced with some nice, fresh grease. Doesn't necessarily need to be a high-temp grease, or anything like that. Let's get it all wiped off there. All right, that gives you
