Does anyone wonder why your machine pukes OIL ? wonder no more.....it's not an "oil tank" it's an oil "trough" with 3/16" gaps under the lid....and a vacuformed flexible PLASTIC reservoir

steel tank support frame.dxf (10.1 KB) Here is the DXF for the backer plate and gasket if anyone wants to perform this mod.

So you going to patent that repair?

Looks very nice, I hope to find some free time and do the same thing

I’d like to see Langmuir do this mod to ALL machines before they get sent out the door…so no one has to suffer through this headache again. After it’s all figured out, it could be completed in 8-10 hrs. there are a few hard parts like getting the bolts out of tight spots and it takes 3 or 4 hose downs to really get all the oil out of the seams and electrical connections. I simply cannot tolerate oil leaking out of a brand new machine and the only way to get it to stop, is rip into it and get it done. all cleaned up and ready for service again - until the next problem rears it’s head

It’s the only way to really get all the oil out after a major dump like this.

The tank doesn’t have much churn during operation, so I don’t think your leaks are due to the tank. I would just start from the top of the hydraulics and feel your way downwards. Message me which of your parts that are wet is the highest up and I can help you fix up that issue. I wonder if this is just a loose plastic return line on the barbed intake. If that is the case some zip ties or a hose clamp would fix that.

Very impressive work there! The rubber gasket is a great solution.

Note that not all rubbers are suitable for hydraulic oil.

True

Materials That Offer Excellent Oil Resistance
Nitrile
Viton
Neoprene

I used Neoprene on this .063 thickness Amazon.com

I have used rags trying to find a leaking fitting and have not found anything that leaks. I even wrapped shop paper towels around the fittings and ran the machine and all of the towels are still dry. I’ll take a look tomorrow when I’m back in the shop and see if I can find anything leaking. I think I’m going to have to take it all apart though soon as oil is everywhere inside the electrical cabinet. It’s leaking all around the seam under the cabinet.

Sounds like it is just a rim leak. We might have over-filled your tank. The fluid doesn’t slosh around during operations so it shouldn’t continue leaking at this point. I’ve messaged you with some more suggestions on how to handle it.

Looks good!
