Upside down bottle jack.

[mtt.tr]

Very simple but it works takes about half an hour
Empty the oil

Undo the top nut and pull the piston up and the outer sleeve off

Find the inlet might have a push on gauze. machine it to accept a push on fit pipe I use 8mm high-pressure diesel pipe as its straight and off good quality also cheap for small lengths.

Push it all back together put the nut and ram back together fill with oil turn it upside down and job done

If you choose to the screw thread is swaged in, carful bit of grinding pull it out makes it possible to fit other tooling


This one will be used for a small c press

My next one will have a remote resviour that's done by drilling right through the inlet hole tap and put a pipe to res on the back side and blank the hole inside the the jack body.

Nicely shown!

I could have done with one of those a couple of weeks back when I needed to jack my van down to wash the roof

ive seen others adapted to take an external reservoir so the that the jack is always full, but this is better and more compact

One other thing should you do my option of remote res don't forget to do the same to the return then its almost a complete circuit meaning the res can be in any position.

With that modification can the jack still work the right way up?
Forgive my stupidity but could I drill the inlet hole for the suction pipe on a pillar drill? And what sort of tolerance is required to get the pipe to stay in the hole?

Am I dim? I can't follow your description.

Not just you, I'm lost.

Basically you dismantle the jack and add a short length of pipe so that the jack will pick up oil when it's upside down.

But it will only work upside down. It's rather simple. Just look at how the jack has to work.
