Video Transcript for etrailer Trailer Jack - Side Frame Mount Jack - TJD-12000SP-F2 Review

Today we're going to be taking a look at the Square Direct Wheel Jack with the included drop leg. This heavy duty jack is going to let you raise and lower your trailer. It's going to have a lift capacity of 10,000 pounds, and a support capacity of 12,000 pounds, so it's a nice, strong, dependable jack. It does come with a drop leg that has spring return, so that's going to increase overall extension for maximum adjustability. Right here, this is going to be our spring loaded plunger pin. It's located at the front of the jack for easy access. You can see right now that I have part of the drop leg exposed.

I did that for our demonstration because I want you to be able to see what that looks like, how it operates, how it's set inside that inner tube. The inner tube is set inside the outer tube, so 3 components: outer, inner, and drop leg. This drop leg's going to have a 5 hole adjustment. 1, 2, I have it set on 3, 4, and 5. Now, the drop leg travel, again, is 13 1/2 inches.

That's measuring from the center of this hole to the center of that very first hole, or from outer hole to outer hole center on center. 13 1/2 inches of travel with the drop leg. That can be adjusted in increments of about 3 3/8 of an inch. That's going to be the distance that we have between each hole. 3 3/8.

I just want you to get a good understanding of that. It's a really nice design. Internally it's going to have a durable inch and a 1/4 jack screw. That's going to allow for heavy lifting. Maintenance is pretty simple with the jack. You have 2 grease fittings right here.

That way you can attach a grease gun. They're built in. Attach your grease gun, pump the grease in to lubricate the internal components. We're looking at a steel construction, so the outer tube, inner tube, drop leg, foot plate, handle, all steel. It's going to have a black powder coat finish on it so it's going to do a great job at resisting rust and corrosion and looking good and lasting a long time. The side wind handle. It's got a nice curved design to it, curved edges, so you don't have to worry about any sharp ends or sharp points. This is included as well as the hardware to get it attached to that drive pin. It's also going to come with a weld on clip. This is to secure the handle during travel. They do include that with it. The footplate. As you can see it's a pretty nice large design. It's welded to the bottom of the drop leg. That's going to give us a measurement going this direction of 8 inches. Going this direction we're looking at about 8 1/4. That's going to do a great job at spreading out the applied weight. It really helps minimize sinking into soft ground. It's also going to increase overall stability. Again, this is a direct weld on installation. The outer tube, we're looking at a square design. That's going to measure 4 inches by 4 inches. The inner tube, we're looking at about 3 1/2 by 3 1/2. Drop leg, 3 inches by 3 inches. With the jack in the fully retracted position, so with the drop leg fully reduced or fully retracted, with the jack fully retracted we're going to have an overall height from the bottom of the footplate to the top of the jack, this is our retracted height of 28 inches. With it fully extended that's going to measure 40 1/4 so the jack itself is going to have a travel of 12 1/4 inches. Then again, that drop leg adds an additional 13 1/2 inches of travel that can be adjusted in about 3 3/8 inch increments. When it comes to adding a cross tube you can definitely do that on this point here. A couple measurements that are helpful when it comes to adding a cross tube, the drive pin diameter. That's going to give us a diameter of 1 inch. Then the mount hole diameter, located right here, that's going to be 3/8 of an inch. That's going to do it for today's look at the Square Direct Wheel Jack with the included drop leg. Again, this is going to have a lift capacity of 10,000 and a support capacity of 12,000 pounds.

Thank you Thank you very much if they would let me give you 6 stars i would. I had a jack go bad over the race weekend trailer was stuck on my truck.So i called my trailer MFG on Monday and they put me off for 2 days with no help. So i decided to pull the front metal plate off found out that is was a ram jack so that night i found you thru ram jacks sent me to etrailer.com so i ordered it. You packed it and shipped at 4am your time the next morning i paid for 3 to 5 day shipping and i met the UPS guy on Thursday morning you got it here a day sooner. 6 hours later the trailer is off my truck after cutting and cutting grinding and welding trailer MFGs weld these on before they put the walls in so welds in blind places. The product is a very good but your pricing rocks and your service is the very best great job you have all my business for trailer needs. 660927

  • Can Pin for Drop Leg be Moved on Pro Series Square 10,000 Pound Jack # PS1401010376
  • The pin location cannot be changed but we do have Pro Series jack # PS1400950376 or # PS1400980376 which do have the pins on the front (or back depending on how you have the jack positioned). Another option is # TJD-12000SP-F2 or # TJD2SP-12000SP-F.

  • Can the Square 2-Speed Jack w/ Crank Be Used In Tandem
  • Yes, in order to use the Square 2-Speed Jack w/ Crank part # TJD2SP-12000SP-F in tandem you would need to obtain the correct follow leg which is the Square Direct Weld Jack part # TJD-12000SP-F2. The handle for this follow leg can be discarded as you would want to use the handle on the lead leg with the two speed operation. There would then need to be a cross shaft made to connect the two jacks but we do not offer this. That said, a trip to your local hardware store would allow you to get...

  • How to Replace Interior Ram Jack Rod and Nut # TJD-12000-RODNUT on 12000 Series Jacks
  • Good news! I was able to get a exploded diagram as well as a set of instructions on how to replace the rod and gears # TJD-12000-RODNUT in the # 12000 Series Ram Jacks made after 2012. I have attached them to this page for your convenience. Basically, you will not need to remove or cut the steel plate inside the top of the jack to do this. You will want to remove the cap, then the roll pin that holds the cross shaft into the leg, this will free up the smaller gear that will be removed...

  • Dimensions for Replacement Square, Direct Weld Jack Inner Tube with Spring-Return Drop Leg
  • The drop leg portion of the Replacement Square, Direct Weld Jack Inner Tube with Spring-Return Drop Leg # TJD-12000SP-FIP measured about 3" square and is about 19" tall. Please note that this part is a direct replacement for jacks # TJD-12000SP-F2, # TJD-12000SP-R2, or # TJD-12000SP-R2NH so if you don't have one of these you will likely need to do some modification for this to fit.

  • Threaded Rod, Gears, and Pins for Ram Square Sidewind Jack
  • For your Ram 10,000 lb jack, it sounds like you will need to rebuild it as the amount of force used most likely damaged the gears and the threaded rod. I recommend the Replacement Rod and Nut for etrailer and Ram Square, Direct Weld Jacks - 12K # TJD-12000-RODNUT along with the Replacement Sidewind Gear Kit for etrailer and Ram Square, Direct Weld Jacks - 10,000 lbs # TJD-12000-GR designed for use with TJD-12000 Series jacks. There is most likely not a clean and easy way to remove...

  • Recommended Weld-On Square Jack with Removable Handle for 4 Corners of Trailer
  • The Pro Series Square Jack with Footplate - Drop Leg - Sidewind - 15" Lift - 5,000 lbs # PS1401600383 cannot have the handle removed and reinstalled easily. It would require opening up the jack each time. I recommend using the Square Direct Weld Jack - Drop Leg w/ Spring Return - Sidewind - 12-3/8" Travel - 10K # TJD-12000SP-F2 for your application.

  • Replacement Inner Tube and Drop Leg for 12K Pacific Rim Trailer Jack
  • For your 12K Pacific Rim square jack the correct inner tube with drop leg is the part # TJD-12000SP-FIP.

  • Best Single Speed Jack To Pair With 2 Speed Square Tube Jack
  • These are both great questions! Jacks with 2 speeds have the gears changed by either moving the handle to a different spot on the jack, or having the handle pushed in or pulled out to change the gear that is engaged- with this specific jack, you'll push the handle in or pull it out to change speeds. With a dual speed jack, the input speed is changed but the output speed does not change, so you would be able to use a 2 speed jack as the lead leg and a single speed jack as the follow-...

  • My 10,000 LB Jack On My PJ Trailer Won't Work and Is Weld Mounted
  • When these types of jacks fail, they often just need to be replaced. You may be able to find a part if you were able to dismantle it and figure out the issue, but that part may not even be available as a replacement. Since your existing jack isn't working for you, I recommend replacing the jack. This does entail having the old jack cut off and welding a new jack to your trailer. The trailer jack I'd suggest would meet your needs is the Square Direct Weld Jack - Drop Leg w/ Spring...
