How to trace a leak, Kymron ZX22

[Jrasband]

My Kymron ZX22 has a hydraulic fluid leak that is baffling me.

I have removed most of the panels and washed everything down with degreaser multiple times. I parked the machine on level ground. I have been able to narrow down the area of the leak to but still am unable to find it. The leak is located under the floor board on the right side, buried underneath all of the hoses in the picture, and is leaking when parked. The oil is pooling on the plate underneath the hoses.

What else can I do to trace this leak? I think I need a inspection mirror as I am not able to look at the underside of where the leak is. The area is basically walled off on the sides as well so I am just able to look from above.

They make a dye you can add and it shows up with a black light, might help.

What he said

You can get a kit online or at napa, autozone, etc... I've used it quite successfully in both engine and hydraulic leaks as well as a radiator leak. They make different dyes for different systems.

To make it easier on yourself, clean everything as well as possible. Add the dye. Run the machine for a while, then if you can, park in a garage or barn. Do it in the evening so it'll make it easier to detect the leak with the black light.

Good luck.

If you are saying that the area suspected of leaking cant be visually seen because of lack of access, what other options are there besides an inspection mirror or USB inspection camera? I would think an inspection mirror would be the easist and least expensive option to try first.

Yes that is what I was saying. I was wondering if there was a way of finding the leak that I didn't know about that's why I asked. I am going to start with the inspection mirror.

You might search or ask on the chinese mini forum on fb if there is some kind of common leak in a particular spot on your machine. Like some say the O ring on the pump hose has been crushed on some models of minis…not saying yours…just a possible example.

The other challenge is figuring out the source of the leak when things are already soaked. Sometimes must clean it up and then look.

Check tightness of all fittings before beginning to spend money. Things like that just pop into a penny-pinchers head.
I might have to become a nickel-pincher in the future.

I found the leak, it was a loose hose clamp. There is a rubber hose which connects the intercooler to the hard line and the clamp on the hard line side was leaking. I moved the clamp closer to the end of the hose and added a second clamp.

Thanks for everyone's help. It was the inspection mirror would allowed me to find the leak.

Glad you figured it out, if you didn’t know there is a Kymron owners FB group. I have a YH 14
