I fixing to build one of these. I have a K181 and a Hiem-Warner pump sitting around doing nothing. Got some parts coming for the pump. Gotta get some pullies and a belt. Rig up a gas tank and a place for the battery. Also a lever to operate the pump. Stay tuned. Depending on parts and weather, I'll be working on this. Just think about a two wheeled dolly, this will be similar. It will be a temporary thing, as the pump will make it's way onto my 108 Cub this Spring.

Made a run to TSC just now and picked up the pulleys, belt and some other things needed for this. Once the weather cooperates, I'll make it happen. Next two days will struggle to get to the high 20's. Wood stove won't handle heating that with the South wall open to the elements!

What are you planning to use the test stand for - used cylinders?

 

Look forward to seeing what you come up with.

Look forward to seeing what you come up with.

I have a couple cylinders to do. But mainly for a pair of Char-Lynn hydraulic motors. I want to see if they do work and at what speed. I will have my gauge inline to see what pressure I have with it. And I have a project in mind that I could use this to test how it will work without hooking to a tractor.

 

One thing I am wondering about is the fluid for this pump. It has a sticker that says to use 10W motor oil. It had tranny fluid in it. I am using tractor trans-hydraulic fluid in my hydro tractors. Will the trans-hydraulic be okay for the pump? It is about 20W consistency.

I would think trans hydraulic fluid or Dexron III transmission fluid should work ok - could even use power steering fluid.  Just be careful you do not starve the pump for oil if the capacity of the cylinders is very large as the reservoir was only designed for a small capacity short stroke cylinder - on the outward stroke the returning oil volume will be less than the amount pushing the cylinder out.

Yeah, that will be something to watch for. Especially with the motors as I want to purge fluid through them and not return to start with. I have no idea how clean they are inside.

That pump will work nicely for testing if the motors work along with cylinders.  But the speed of the motors would depend on how much flow you put to them. If your planing on using this guy to run the motor in your future project, then your set.  I have a similar  pump motor and control valve setup off a JD. The pump is a rather small displacement and doesnt flow very much.

The main thing on the motors is if they will even work. An approximate speed will be nice to know. They could be low speed/ high torque motors for all I know. I tried to find them using the #'s on them some time back, but couldn't find anything on them. Have to dig them out to get the #'s again.

Just found some info on the pump.

2.5 GPM @ 400 PSI

Should be okay for testing things out. I will put the gauge inline just to check it out.

Kenny, is that cylinder from that pump set? As it is a low psi rated unit..very poor stuffing box design..

Yes, it came with the pump.
