Lifting the trailer

The adapters being discussed are designed to fit over the circular top of a standard bottle jack. As has been noted earlier, different jacks have different diameter tops. These adapters will NOT fit the top of the combination jack/axle stand that I use. The top of this jack has a flat centre section and two lifted ends. The problem with using this jack as-is is that the thin wall tube axle would be lifted by the flat section . . . not a good idea. I welded 3" ID half circles to the tops of my jacks to nest against the axle tube. Quite honestly, the prices that I see for the referenced jack adapters are kind of crazy. I would think that any fabrication shop could weld the half circles to the tops of the jack extension piece for a few dollars.

For changing a flat tire we use our lego-leveling blocks to stair step the other tires up until we can change the flat (I really like the versatility of these blocks and keep finding new ways to utilize them). This does increase the load on the other two tires but only short term and with no impact loading.
For maintenance (checking the brakes, greasing the bearings and blocks) I'm not really into that and so let the dealer take care of it once a year.John

This thread gave me a couple of ideas for when the axle would be closer to the ground like if a tire goes flat.
A double ram bottle jack that's about the height of a stubby bottle jack with double ram for more lifting height.

An Axle Spring Mount/Perch to place between the u-bolt and and then slip the bottle jack beneath it before jacking up the axle.

Great ideas Gene! The combination jack/stand that I use just barely goes under the axle with a fully inflated tire. With a soft/flat tire, I would have to first roll the other tire up on to blocking. The much shorter double ram jack and adapter made from a spring mount are great ideas.

The seats are per pair, and even lower cost on ebay, serach: trailer axle spring perch.
These are 3" mounts I linked so I'd verify your axle diameter.Last edited by gbkims; 12-25-2019, 03:59 PM.Gene and Kim

This is a brilliant cost effective solution where I will order an axle saddle and weld on a section of pipe to the bottom. What are your thoughts in leaving the wood section a little proud like 0.030 of the metal bracket?

Note: I came across these ideas while searching online. I figure the idea has been passed around for awhile.Last edited by gbkims; 01-17-2020, 07:27 PM.Gene and Kim

For the type of service you ask about, I lift just the axle end until the tire is off the ground. I do this with a "saddle" on the top of the jack that fits to the OD of the axle tube between the U bolts. I know that the axle manufacturers say to "lift only by the frame" but, I have seen their own technicians lift by the axle ends. Usually with a block of wood under the U bolts. You should never lift by the centre of the axle tube because it does not have the strength for this.
Lifting by the frame means that you have to lift the frame several inches, either twisting or tilting the entire trailer before you get the tire off the ground. Lifting less than 2" at the axle end gets the tire off the ground and puts none of these twisting/tilting loads into the trailer body.
I actually store our Reflection with the four tires just off the ground using four of the (relatively inexpensive) jack & axle stand combination units described in the attached.
Rob
This is really sound advice where these very flexible coaches would twist a great deal if lifting at the back of the frame. I've been lifting with a bottle jack ahead of the front axle and aft of the rear axle for projects such as the MORryde and spring replacement. Your advice on lifting at the axle end with the proper cradle (critical) is perfect for those small tasks such as a brake adjustment or to change a flat tire. Also excellent on the storage jacks. The collective knowledge on this forum is just priceless.
