Can someone please tell me what the metal end on this hose is called? I want to fabricate the hose but I do not have the metal end and I cannot find it online. Thanks.

I am the maintenance tech for a small local golf course and I’m currently working on a toro reel master 3555-D model 03820

This machine is having issues with the front left hand cutting unit (#4) dropping significantly lower than the other 4

I have rebuilt the cylinder twice(preforming piston seal bypass tests each time) , swapped hoses to make sure it’s not internally bad, installed a new cartridge valve for S1, checked to see if have correct pressures coming from my pump(2000psi) confirmed all solenoids ohm out correctly( per book specifications), swapped the cylinders to make sure the problem is isolated on the left hand side(it is) checked that my relief valve pressure are correct with speciations from the book

I am at a complete loss any help that you can give will be much appreciated

EDIT:: found the problem a piece of the piston seal has lodged itself in the flow control in OR1 thank you for everyone’s input ✌️

I got this hydraulic lift working on this dump trailer but wiring still needs some love and the battery box is a mess, but it goes up and comes back down which is a win in my book.

What do you all think am I forgetting before I actually load this thing?

Been stuck trying to remove this cylinder for a couple days now, seems to be stuck inside the plungers. Last 2 pics are the “new” cylinder we’re putting in. Thinking of bringing the excavator down here and pulling it out with that as we have limited tools.
Any tips much appreciated

Day to day operation is fine but when I raise above a certain height it squirts oil out of the cylinder.

Hi friends! I want to recreate a geyser/airlift hybrid pump but I’m having trouble understanding the models? The screenshot from YouTube seems straightforward enough but I can’t tell if there’s a check valve at the bottom. Also I’m thinking the grey box is air in the other two models but I’m not sure.

Thank you in advance!

Pompa osłabła. Myślę że da się to jeszcze naprawić. Wiecie gdzie mogę dostać te złote elementy ? Myślę że gdy założę nowe to jeszcze pochodzi. Tłoczki i cylinder nie są porysowane.

hey guys this is my assignment so the dealine is after one day and im using software called {fest hydraulic} i need someone draw or guide me how to draw or where i canget this existed project
thanks every one
~this is my homework at least someone guide me how to draw

Electric over hydraulic bale bed

Started happening all of a sudden one day, draws an incredible amount more power than it used to and causes the voltage gauge to drop all the way down just about causing the truck to die, nothing is leaking a crazy amount and nothing at the cylinders is leaking.

We have to stop as it draws too much power and would cause the truck to stall,

Anyone with experience know what this 2 wire solenoid controls for a Rexroth hydraulic pump? Is it a safety shut off, variable control, or something else? Main picture is a sample I got from google but second picture is the placard from the pump. Thanks

Pressure is jumping all over the place and some functions are struggling when others are in motion.

The pump is a Vickers PVB45A.

Thanks for any insight.

A local tree guy posted an ad on marketplace that he had some maple available, delivered for free. I told him to go ahead and bring it by.

So I learned today maybe I make poor decisions…

I currently have multiple tons of wood on my lawn in the form of massive chunks of trunk that I can’t really move. I beat myself to death today trying to work on it. Luckily I have this old splitter or I’d be screwed beyond belief.

Since I can’t really maneuver the rounds, I’ve been mostly trying to heave the splitter around, which is kind of awful. Got me thinking how cool it’d be to have a self driving splitter. Not fast, obviously, just maybe .5-1mph or something. Drive it right in, shove the foot under, and crunch

Is this even possible? Is there any way to do it cheaply? I was looking around at wheel motors and that’s going to be $400-500 per side. Not worth it. Is there a cheap source for hydraulic motors beyond marketplace? Do I NEED a wheel motor?

Hello, I'm looking for this pump. I'd like to know which pump it is because I can't find it anywhere. Also, I don't know if anyone has a parts diagram or technical data sheet for it.

I’ve got an old Case Backhoe that I’m replacing seals on, and one of the wipers is not like the others. The first picture is of the mystery wiper, and the second is of what the rest look like.

I’ve got seal kits (for 2 piece pistons, going off the number stamped on the gland) for the leaking cylinders, but I don’t have a wiper for this one (there’s only one cylinder on the machine with this).

Any info at all about this will be useful, since my google skills have not brought up anything yet.

I remove the snapring, and below it is this metal(?) seal. How would i go about removing it, its hard and my pick cant really find a spot, would appreciate any help.

Thanks
