I highly recommend these. This is the first time I have used them, but they worked beautifully! Soft enough to bend but strong enough to install and remove. These will push into a hose or fitting. 90 degree fitting?..no problem! They saved me from draining the entire hydraulic tank and the oi l cooler above my work area. They were strong enough to hold back 30+ gallons of hydraulic oil at the bottom of the tank. They are kind of like ear plugs..except cone shaped.

I think I paid around $50 for this kit.

I have the yellow kind but for some reason mine slip out if there's any pressure build up even just oil falling down a tube, a coworker gave me a set of orange ones that have shoulders on them and sometimes they stick so well I have to really yank on it to free 'em.

Oops hosspuller linked to the ones I have, mine are grungy enough I don't think you can read the name anymore.

I still do some commercial work and the last 2 big cylinders I did went to the hyd. shop came back at 26K apiece.
they were 16 and 18 feet long and needed new rods.
I use a hyd shop for their warranty and parts and quick turnaround.
I get a tested complete cylinder ready to put on that I don't have to worry about.

Wow, what size machine was that?

Oh I've got to have one of those kits. I hate oil running everywhere, and I really dislike pumping out 100 gallon hyd. tanks to replace return lines.
Cat transducer. P/N 216-0244 . They have adapters to fit all kinds of hydraulic tanks and fittings. It is a venturi that pulls vacuum on a system so you can change components with minimal spillage.

I made this years ago and it has always worked well. I think I got it from a Napa store and I made the adapters for fit it. Cost less than $10 back whenever.

How is it used? I don't work on hydraulic systems often and usually end of draining the tank when I do. But I'm absolutely open to methods that save time and make a job easier.

It is what is known as an eductor. I hooked up the male threaded side to my air compressor. The air goes into that through a small orifice and it opens to a larger space above the male hydraulic adapter that I attached to a fitting that I installed on a plate on the top of the reservoir. It takes somewhere around 4 to 5 CFM on the air side to make it work. I have never measured the amount of vacuum that it pulls but I could pull the suction hoses off a PC400 pump and hardly have a drop of oil hit the ground.

Well if we are all showing off our tools!:oops:
hyd tank tool.JPG
This is one I built after we had a class at the shop with a Hough mechanic. It was a very handy tool if you were working on hydraulics in those H- series Houghs and the later 560 and 400 Houghs and Dressers. As they all had the hydraulic tank mounted directly above the pumps, many of those being vane type Vickers. So many lines on the machine would cause a major oil leak while changing a simple o'ring.

Using this simple tool and a piece of cardboard if you were careful and no one turned off the air compressor you could actually remove one of the pumps with hardly a drop of oil on the floor.

The cardboard was the trick. With suction device connected you could loosen the inlet connection and slide it up just enough off the top of pump to slide the piece of cardboard between the pump and inlet coupler. The vacuum in the tank working on the approx. 7 square inches of the inlet pipe were more than enough to keep the oil in the tank.

In those days, service trucks had gas engines and we carried long hoses that would connect to the tanks. It made the engines run a little rough though. I know of one mechanic who had the vacuum going from his truck and while pulling the pump from the 560 log loader, someone came by and shut off the truck engine. There was an eruption of some colorful language, so I've been told.

I use a shop vac. Duct tape the hose to the reservoir neck. Poke holes thru the duct tape with a pocket knife to lessen the vacuum. Variable speed shop vac is the best. Pulled many a suction screen out of a farm tractor tranny without losing any oil. Works good if you want to check the magnetic drain plug without draining the oil.

Yep I did that gas engine trick a couple times. Once while working on a control valve for some load, maybe Michigan. Only problem was it managed to suck some hydraulic oil into the Fords intake. Took a good 2-3 mile run at high speed to stop laying down the smoke screen behind me!
