I had to go back and look again at the first pix. I had the idea that the primary seal was at the shoulder of the piston and moved with it, but that lower seal under the cap is really just to seal...

Usually, you can get away with measuring either the bore of cylinder on the wet side of seal or the biggest part of the piston on the wet side, as the clearance is usually quite small. This is a...

That is pretty inexpensive, for sure, especially in US$.

I am surprised that they can get by with an oring seal for that much pressure. Usually, you would need a self activating lip seal with a...

Now you know why most of them have a bolt in the middle of the ram, so you can use it to fill the major part of you clearance before you pump them up. Bummer they took it out.

The issue with hydraulic or air cylinders swapping oil or air is extremely common in industrial equipment, and is why you very, very, rarely see either of them used in an application where they are...

If the 3 weren't tied together, centering wouldn't be a big deal as you would just add them together. With them tied together, the fluid will be able to go to any or none of them when compressed, so...

That would work, but you would have to be very careful about air, as Marko mentioned, as well as be centered well.

Yep, same deal as I was thinking of. Hardest part would be getting the 3 gauges in there and easy to see, I think.

Add the pump to them and you could read remote and have them retracted while...

Stability would have to be a big issue for a drive, I think, due to the very small area of the ram and the base of both the hydaulic and electronic sensors. Using two of them with a plate would not...

Having the hole in the top would be nice to pull it up, but not critical, I guess.

It looks like the locking ring in your pic is two slots, on on each side. If the piston is low enough just a...

Thanks Marko. Don't know what happened when I searched Northern a while ago, as it all it came up with were the expensive ones.

What brand and source did you decide on for the gauge vendor? A quick look showed the cheapest ones on ebay, with others usually quite a bit higher. I think $17 for a 1500# gauge there.

Lots of that kind of stuff going on, for sure.

Add to it the way a lot of meters and gauges are rated, and it gets even worse a lot of times. Many are rated as a % of full scale, which can be a...

It does look like the 1500# gauge would give the best results. It would use the maximum amount of range on the dial, which always gives better resolution and guesstimation between lines.

Always...

I was just looking at Harbor Freight, and they also have a 20 ton version of the ram, which I think would put you on a 1000 psi gauge for 4000# capacity, if I estimated the cylinder size base on...

Did you have any problems with the front wheel spinning, or was the plywood enough to steady it?

Doing one wheel at a time with a height difference will give an error due to angle that is pretty small (sine of the angle thing), but what will mess you up is if there is a sway bar on that axle,...

I do think that would work and could be made safe. The hardest part is keeping the wheel off the ground from turning, I think. The rear is easy because you can set the parking brake. On the front...

I like that, and not horribly expensive.

I think you could easily make it accurate if you supported the opposite side of the end you were measuring at the same height. The hard part is going to...

Corner weight vs axle weights

When we made the change from 375ah of wet cells to 440ah of AGM in our 07 Roadtrek 190, the batteries moved from the stock locations which were on the far outer edge of the passenger side, in front...
