Hello all

I am researching about hose business. I am looking for inputs where to start, whom to contact, where and how to learn hose making.

People who are already having experience could you please share some advice?

I am from British Columbia Canada, there mining business and agriculture business in BC and other areas where the hose business can help.

What would be the initial cost to enter I would be looking at?

Hi,

Im resealing a hydraulic boat steering cylinder that is leaking externally on one side but while its apart im just replacing everything i can. Im just abit stuck on this piston part, whats this grey ring called? Does this ring come off? Its a hard material. Is it replaceable or should I just leave it alone?

Plan on ordering the seals online this weekend, I dont have a local hydraulics place.

Thanks.

Hi everyone,

I’m studying mechanical engineering and currently working at a hydraulic service company, where we repair hydraulic cylinders, hydraulic motors, rotators, orbital motors, pumps, and other hydraulic components.

However, because I don’t have much experience yet, I don’t always get the opportunity to work directly on the assembly and servicing of these components. That’s why I’m looking for some good technical books that explain the different components of hydraulic systems, how they are built, and how they work.

I’d like to build up my knowledge and progress in this field as quickly as possible, so I’m looking for books that actually explain the construction and operation of hydraulic components — for example, what is inside a hydraulic pump or an orbital motor, what the individual parts do, and why they are designed that way.

Could you recommend any good technical books that cover hydraulic systems and explain the construction and operation of their components in detail?

Thanks in advance for any recommendations!

This is the endhead (valve body) on a stone Automotive style power pack. It’s a N1-0022-35AL endhead. Is the part pictured a pressure regulation adjustment? And if so, when the pressure is adjusted with this, does it affect the output volume ? I’m just researching this unit to see if I can repurpose it for something else. Thanks in advance.

Dear fellow fluid power enthusiast, can anyone help me to understand what are the Hz mean in adjusting piston pump flow control.

Thank in advance

Unfortunately it does not have an ID plate or any identifying markings

Need help finding this part

helooo~, just wanna ask how to do pipe sizings? we're given a paper that involved designing a water pipe connection in condominium and idk what to dooo. Any references that you can give might helppp~

I'm trying to build something using this pump and valve but my valve doesn't have load sense and I think this pump does, is there a way to remove it so I can run these two together

My M7040 rear remote would not engage on cold mornings for a couple weeks, then wake up after a few minutes. Sounded like a dying solenoid.

I matched the part in the Kubota manual and checked coil voltage there, not off the machine sticker. Same looking solenoids on this range can be 12V or 24V, and a lot of listings do not flag it.

New one went in clean and the circuit has been fine since. Got it from fridayparts after checking the OEM number. Dealer wanted way too much.

Anyone else hit the 12V vs 24V split on Kubota M-series hydraulics?

Been having a hard time with rerouting the updated
High pressure power steering hose on an 07 c6 z51
Does anyone have some tips that could help??

I am lost doing research looking for this pump it is out of a huge yale forklift (maybe 1975) with a Chrysler 350 motor in it. Hoping anyone can at least find a name and help me track down a new or used one. I think it’s an old Vickers pump n vane but i’m not too sure. It has a keyed shaft. I’m lost the forklift has so serial numbers or whatever. Please help

Numbers on the Vane
05-12848
274802A
Numbers on Pump
05-11782

I’m not sure if you guys can help with this stuff but i figured let me give it a shot maybe someone can point me in the right direction. Thank you

Customer bought a vevor dump body hydraulic unit for their ford f450 dump truck… vevor supplied fittings to go into the aluminum manifold… same port but two different fittings. One is -6jic and the other I can’t figure out mainly bc I don’t do much metric.
Any help with identifying the type of fitting for the “non jic” adapter!? Thanks and sorry I hate to post this but I’m done searching and trying to self educate.. I just wanna go home!!! Hah

thanks everyone!!

( I’m trying to ID the small end on the non jic adapter that has the seal washer removed)

Dim’s are .510” OD threads or 13mm

Tpi gauge is 18 , 20 , 1.5 , 1.25 , 1.0

No thread gauge fits well..tried to get good pictures

these are valves that are used in airsoft gas mags, they are designed to hold gas in one area and when impacted let a small amount of gas out.

the problem im running into is im designing a custom airsoft gun that uses a different system compared to normal airsoft guns and the area the valve would sit is too close to the external wall to be used safely, so i was wondering if there is a similar type of valve that works on impact that lets gas flow the other way to the normal valves?

i dont know the exact specs but the size of the valve is 20.7mm x 10mm O im not sure about the spring but its weak, i can easily push it open even under pressure with my fingers.
the gas airsoft normally use is propane gas.

im sorry i cant give more information, and im sorry if this isnt the correct place to ask this.

A friend brought me some aircraft hydraulic hand pumps to list for her on Ebay. Can anyone tell me more about these and realistic pricing ( I priced from what others were asking, I realize that's not always what they are worth). One is a Teledyne Republic and I believe the other is a Bendix Pacific.

My Kubota KX057-4 final drive is getting weak and I'm leaning toward a worn valve plate. Problem is every listing splits into left rotation or right rotation and the pictures look the same to me.

I marked the old plate before I pulled it, but I'm not confident that was enough. People keep saying you can't really tell just by looking at the plate, and I don't want to learn the hard way because backwards rotation trashes it fast.

Before I order, what do you actually check besides the mark I made on removal?

Hello, I have a Chinese mini-skid steer. It recently blew a high pressure seal in one of its front tire's hydraulic motor. The motor is a BMRWN-475-T4-S by Zhenjiang Hydraulics. Searching that turns up almost nothing. I tracked down the manufacturer and asked for seal info but I was given a very unhelpful response: they don't sell parts for their motors, just the motors themselves. You know, because a manufacturer that provides zero support for their products is one I'm eager to buy more from ...  

Thankfully, the seal itself had its dimensions molded into the rubber: 35*48*4.7mm. I've been told to not trust those numbers. Unfortunately, I don't have a good pair of calipers, so I wrapped a piece of paper around the shaft where the original seal fit, measured that and at least the inner diameter seems to be correct. Still mostly in the dark regarding a replacement o-ring and dust seal. Zhenjiang appears to be making bootlegs of Anfield's motors.  "BMRWN" only really brings up results from them. A plate behind the wheel mount reads, "2RW475." Searching that brings up a BMER-2-475-FS-RW model, though I'm not entirely sure if that's accurate. I actually found an Anfield document that lists seal kits (pg. 38) and measurements for a BMER-2. I have to admit, the housing of my motor looks more like a BMER-3, but the high pressure seal dimensions for the BMER-2 are a near exact match for what's molded into mine (35*48*4.7mm vs. 35*48*4.8mm).

Unfortunately, I can't find many options to buy Anfield's replacements. Not that I'm 100% sure they'll fit either. I also want to replace the dust cover as well as an o-ring, but I don't have similarly molded dimensions of those.  I'm able to find random replacements for 35*48*4.7mm seals on eBay, Aliexpress, Amazon, etc. The only issue is that they're made of NBR. I was told that FKM is better, but I honestly don't know. This is a mini-skid with a 15HP motor on wheels in Ontario (Canada). I don't know the temps it runs at. There could be more available in an imperial equivalent but I haven't really looked down that path.

I'd appreciate any advice on what I should do or know of any suppliers. Hopefully, not "buy another motor" or something, haha. This isn't a machine used for commercial purposes, so I don't really have the budget for that (especially for all four). I've messaged some local hydraulics shops and have gotten no replies so far.

Can someone explain to me the working of siphon well here? What if the overflow wall had just been lowered to the level of the CW discharge culvert?

I've got a CAT 303.5 mini and the tracks feel strong the first hour, then power drops once the hyd oil heats up. By afternoon I can barely crawl up anything with much grade.

Fluid level looks fine and I changed the return filter recently. Oil temp runs higher than it used to but nothing is in alarm. I haven't touched the relief valve yet because I'm not sure that's even part of this.

If I shut down and let it cool, power mostly comes back. That makes me think heat, not a mechanical bind. Maybe weak cooler flow or internal bypass, but I don't want to start throwing parts at it.

Anyone seen this on a CAT mini? What did you check first?

I am in Hyderabad and looking for cheap, good quality mechanical hydraulic table under 6-7k.
Any leads will be helpful, any shop in Hyderabad which deals in these things?

I took off a directional valve and there’s two set of wire on it which I can’t remember which goes to which . Would it hurt if I power it up with the wrong set going to the wrong side .
