Hey. I bought this “50 ton” press for forging and it functions at a high rate of speed like I need, but it’s underpowered. It’s a 5 hp 3450rpm @230v motor. At maximum force the gauge reads 650 psi. I’ve got a 50 amp breaker. 36” ram with 4.25” bore. I’ve tried googling this and I get a wide range of answers on motor size. Looking for suggestions from the experts here. 10 hp motor? Larger? 1700/3400 rpm? Do I need a larger pump?

I can install a larger breaker if need be. The hoses are all new. For now it’s working well enough for bending and straightening, but I primarily bought it for punching and drifting holes in hot metal and it just doesn’t do that well. I appreciate your insight.

Is this normal? This gland has a film peeling off that I haven't seen before. Should I just remove it and test?

Lost basically a whole week last season when the hydraulic pump let go. parts hurt bad, thousands before you even count downtime. ngl rough week.

Signs were there for a while. I just didn't know what I was looking at.

Boom got sluggish on empty cycles first. never timed it, just noticed things felt lazy before I even loaded the bucket.

Found metal fuzz on the magnetic drain plug one oil change. should've paid attention sooner, that stuff doesn't show up for nothing.

Arm started drifting in neutral, slow creep I wrote off as an old machine thing. wasn't.

Oil was running hotter than usual and rattling under load I blamed on the frame. ignored all of it too long.

Could also be valves, cylinder seals, or a clogged filter, same symptoms. pressure test before you pull anything expensive. I skipped that.

Which sign tipped you off early?

Got some major leaks fixed on an old truck mounted conveyor. Owner didnt want the old leaky cylinder. Normally I'd just take it to the scrap yard but this thing is like 5 feet tall. Seems wasteful just throwing it away. Is there a better way of getting rid of this thing? Don't think too many people are in the market for this kinda thing but I thought I'd ask haha

Hello, everyone!

This is my first post in this subreddit and I am by no means a hydraulics expert.

I am working on an application that has a tank that holds transmission fluid at low pressure (<100PSI). I want to drill holes into the tank and install two bulkhead fittings with 1/2" NPT female ports on the outside so that I can install IFM (LMC510) sensors to detect high and low levels of fluid in the tank.
(I would prefer to avoid any welding options, if possible.)
I am considering buying one of these two parts for that purpose...

• PARKER HANNIFIN (207ACBH-8)
• MCMASTER-CARR (50785K275)

But I want to ensure that these connections do not leak fluid, of course. Would they leak fluid if all I installed were one of these parts above? How are hydraulic bulkhead fittings normally sealed? Does anyone have any resources I could read/watch to understand hydraulic bulkhead connections better?

Any information or guidance is greatly appreciated!

Hey Im doing a hobby project where I need 2 hydraulic motors (I’m trying to build a small tracked vehicle from scratch) I already have one used Danfoss OMP 200 from where I were an apprentice, and I found a used one online. I’m unsure if it’s a bad idea to buy a used motor though, if anyone here has experience with buying used hydraulics parts how have that went? I would buy 2 new motors, but I’m a student so I can’t really afford them sadly.
Is there a way to test or gauge their condition?

I'm working with garbage trucks in pair with hydraulics specialist, changing pumps, manometers, deinstalling and disassemble cylinders. I wish to know is there some good books about hydraulics.Unexpectedly for me I got kinda hooked to this stuff, really wish to know more about it. Thanks in advance

Hard thing to Google apparently. Getting components together to build a forging press. Do I need to match the fitting/port types, or can I work around it using adapters? It's hard to find the parts I need in Australia, but nearly impossible to find them with matching fittings.

For example, here are links to a cylinder and valve I'm looking at.
The cylinder uses 3/4" NPT ports, whereas the valve uses 1/2" NPT ports.

Valve: https://www.ebay.com.au/itm/335427713523?_trksid=p2332490.c101224.m-1

Thanks.

What are the chances this hose hold up for a power steering pump?

Any idea what the parts store is doing wrong?

When I told them it was wrong. They said this is how the 3/8” hoses all crimp. But only 3/8 the 1/4 and 1/2 are straight and seem correct.

Reposting here because I just don’t know where it belongs. Appreciate your insight!

I am installing a mobile single post car lift for my garage. I am almost done but I can't get the lifting cylinder to sit flush.

The chain is aligned on the pulley and the chain is held to the carriage base with a retainer pin (photo 2) and held to the lifting arm with another retainer pin (photo 3). There is no chain tensioner that I can see. The lifting cylinder and chain came installed to the carriage as shown in photo 1.

I can move the cylinder to the flush position by hand put then it just falls forward as soon as I let go.

Would appreciate any advice.

Need 20L pail of this stuff.

Hello,

Where may I purchase a 20L pail of Fyrquel EHC Plus fire resistant hydraulic oil in Europe. Fyrquel/ICL do not answer inquiries.

This oil for a 80Krpm centrifuge.

regards,

Nick

Best way to put these together in my opinion

My neighbour bought this and asked me to assemble it so I did, however the rod/shiny part (not sure what its called) wont go in to the other part no matter how hard I push, is it defective or do i need to activate it or something?

Looking for some direction from you expert folk. My small Chinese mini excavator gets stuck. The treads aren't skipping, it's just like it has no power to move forward or backward more than a few feet. But the bucket and arm seem to move fine. If the pressure is too high could the hydraulic oil (46) overheat within a matter of minutes to the point it wouldn't drive forward or backward but bucket works fine?

Or is it something else entirely?

The high pressure hoses that go from the hydraulic pump to the main hydraulic valve inlets starts to kickback at around 2,000 psi.

I was called because the movements of the machine were slow, so, after discarding a pilot system problem, I connected a flow meter, the kickbacks when testing it were violent, we only moved the stick arm and the bucket before shutting it down.

I'm leaning towards the pump being bad but how can I discard the main valve? At high idle the flow meter show 36gpm (1 side of the pump) and the peak pressure was around 4,600,.

As a beginner in hydraulics field from where should I start learning if I want to become reach advanced level . Need some recommendation for courses or anything which helps to get a good knowledge in hydraulics & pneumatics

I have a Red Wood gas-powered log splitter that has been sitting in my shed at for about 1-2 years. I recently noticed a small hydraulic oil leak, even though it hasn't been run during that time.

The leak appears to be coming from the seam where the rounded end cap of the hydraulic reservoir meets the main tube (opposite the cylinder rod end). The area circled in red is where fluid seemed to have dripped. There are no hoses or fittings directly above that look obviously wet.

I also noticed what looks like a crack in the paint near that seam. I'm not experienced with hydraulics, so I'm wondering:

Is this joint typically welded, or is there some kind of internal seal or O-ring at that end?

Has anyone seen these reservoirs develop pinhole leaks or cracked welds?

Is there anything else I should inspect before assuming the reservoir itself is leaking?

Any advice from someone familiar with hydraulic systems or log splitters would be greatly appreciated. Thanks!
