Video Transcript for Rebuilding etrailer and Ram Sidewind Jacks

Today we're going to be showing you how to rebuild the etrailer Ram Brand Trailer Jack, this is part number TJA-2000S-V. Also, if you need a handle replacement, it's going to be part number TJA-2000S-HD. If you just need a handle replacement, you'll be using this one. We also have a replacement cap, this is in case you drop something on top of your jack or it happens to become cracked. We want to prevent any moisture from getting in there and causing damage, so we got that replacement. That is part number TJA-2000S-CP.

It's going to come with a set screw that you'll need to install that. Now for the gearing and the jack, it's going to have 2 gears. One is our base gear, see it's designed to hold the pin in place. The other one is going to be a pass through gear, the crank gear itself. You can see where that pin will pass through it. We're going to have the base gear pin, we're going to have our handle pin and a keeper for that.

This is going to be part number TJA-2000S-GR. Then to go along with that and I recommend if you have to change your gears, go ahead and change the bearing as well. This is part number TJA-2000S-VR. That is going to be our replacement bearing kit that's going to allow that screw to turn freely, very low friction, which is going to make it pretty easy for us to raise and lower our trailer. We will start by bringing our jack over and get the other parts out of the way. The first thing we will need to do is remove the cap with a small Phillips head screwdriver for that.

Just pull that up and off. Now inside you will see our gear kit. We've got our shaft gear here, our crank gear on the side and then you can see that base gear down there a little bit lower. Now this gear has that keeper that goes around that slot, it's a little easier to show you here. This is the same gear, it's over against the side and you'll see this little slot on the backside of the gear.

That's where this fits in, so we need to get that removed. Typically a small pic or a small screwdriver is what you're going to want to use to do it. Find one end of it and then lift up on that to get it around to the backside, or the outside of the gear. You can see how it's not sitting over on this edge, rather than being in the groove that's right behind it. Then if we put our pic in there, we should be able to just rotate the handle and push it off there. It's off far enough there, we can get to that pin, see right in that little U-shaped opening on the gear, you can see the end of the pin there. What we are going to do is just use a punch 5/32 of an inch is the size and we'll get that driven through. It won't take a lot of effort, but once you get it started most of the way through, what we need to do is turn that hole from being straight to where it's tilted down. That gives us a little more room, which will allow us to drive that pin our all of the way. At that point, you will see that our handle is free and we'll pull our handle out. If you're just doing the handle replacement, you'll just put it back together. We will set that aside and see there is that ring that went around our gear to help keep it in place. This is the gear itself, it goes on the crank and it's going to be a match for our replacement. Now this little spacer, you saw it fall out of there, that handle just passes through it, just takes up the gap that would be there. We also have the bushings that fit on the outside of the spacers, if you want to call them that. It just gives our handle a wider area to ride on, makes it a much smoother operation, as to opposed there just being a hole cut in the side of the jack there, it has a little area there to ride on. You don't necessarily have to remove these, but they are going to fall out, so we will just take them out now. We want to be sure to get that little pin that we knocked out. That's for our handle. We do have the replacement there, but you don't want it to stay in your jack mechanism. Set that aside then you will be able to lift that gear straight up and off. If you look in there you will see the little pin, the little floating pin there. That one is real easy to push out. Now you are going to pull out slightly on the inter-tube of the jack, and it's just going to slide on out for us, just like that and you will see that is where that bearing is going to sit. That's our friction reducer, that allows the screw to turn without it building up a lot of friction on that top plate that sits right above that. That is essentially all there is to the jack. Just extend the leg out and retract the leg back and these screws are really hard to damage, they are nice, strong heavy-duty screws, so it's a good way to save yourself money by doing these replacements. We take our new bearing, slide that down and on and you will see this little plate here, it's also a washer that goes underneath that bottom gear. This plate just rides on the bottom there and our gear rides on top. It's a thicker slot on one side and a thinner on the other. It's going to go in the thicker slot. Now we will line up the long groove in the inner tube of the jack with the little dimple that's on the outer tube there. Slide that down so our screw now comes up through the plate and then we will put our washer back on. We will grab the pin for that base gear, this is going to be the one without any grooves on it. Right above that plate there's a little gap, like to put it in there, grab it with my pliers and bring it into position. We want that to be about centered, so we've got about equal amounts sticking out each side of the screw there. Now we will just align the bottom of the gear with that pin. We waNt to make sure it seats all the way down, which really doesn't take any effort to do it, it just slides right on. Remember we have these on each side, so these need to go back in. Now we just want to get our handle started. Place our keeper ring on it, we can place our gear on and the handle itself just passes right through the gear. Now remember that spacer, we want to put that in place. Our handle goes right through it and it will come out the other side here. Now it's time to turn the gear, so that we can see that open, or that U-shaped slot in there and then you'll also see the hole for the handle that lines up with it and it's time to put our pin back in place. Place it in and then tap it into position. All right, one we got that about equal, we're going to start our little snap ring and get it put back on there. All right, see it's snapped back in place there, it's going to keep that pin from sliding out. Now you want to use some good quality grease. Any standard grease will be fine, just want to keep plenty in there to keep it protected. Be sure it works in there really well and then we'll be ready to put our cap back on and start using our jack. Now this is a really simple installation as you can see. It would be a great way to save yourself some money, rather than buying a new jack. There's not a lot to them. Just put our screw back in and that's all she's got. That's going to complete our rebuild. I hope it shows you how in just a few parts and a little time you can rebuild your jack, rather than completely replacing it.

I thought it was going to be a difficult task to accomplish, but replacing the gears were very simple and easy. Just watch the company's videos. They show the process of how to.


I wasn't able to to find the gears I needed to fix my jack at the local hardware store so started looking on the computer. Finally found and got a phone number and was helped by a very friendly and helpful gal. She kept in contact with me every step of the way as the gears I needed were on back order from over seas. It took several weeks to finally receive the gears in the mail, which I was perfectly ok with considering a new jack would cost $60-90 and the gears to fix this one with shipping costed less than $8.

The jack is still working like a brand new one! Just remember that in the winter, dont force the jack as its most likely froze and that will cause you to look for parts or a new jack.

Good product works well


These parts are for the etrailer and Ram sidewinder jack. My jack is by Atwood and look identical. Unfortunately the hole for the gear keeper pin was off center.
This was not etrailers fault or problem.
With a Dremel tool was able to modify the crank gear and to then complete installation of the kit into my Atwood.
note: To make handling the jack easier I cut 2.5" hole in end of a 1"x4"x12" board and attached it to the workbench with the hole overhanging. Dropped the jack in and had both hands free to work on it.


Parts were for a military trailer parked at an undisclosed area. They were an exact match to what was described and melded perfectly into the existing apparatus.
Parts came ahead of schedule and in excellent condition.


Better gear than the one jack came with


Gears worked great good quality
