Hydraulics

Due to its immense power, hydraulics are used for operating various machinery, vehicles, aircraft, ships and equipment. The data and engineering revolving around hydraulics is so vast, its hard to comprehend.

What is the difference between hydraulic action and abrasion?

By: Gwen

The difference between abrasion and hydraulic action is that:

In "Hydraulic action" the water flows so fast that it is forced to crack the bank

BUT

For in "Abrasion" the river bed is broken/cracked because of the rock and stones in the river.

Where do you put hydraulic oil in Massey Ferguson tractor?

Hydraulic fill is on top of the transmission but be sure to remove both drain plugs at the trans and back end as they are connected before refilling.

Dams
Hydraulics

Why the base of the dam is made wider?

The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.

How do hydraulic brakes impact society?

I do not think they have a direct impact on society; however with the improvement to road safety (much better stopping distances for vehicles), they may have had an effect on society. One other aspect; they have allowed people to travel faster (because of the better safety); but this is not just hydraulic brakes, this would include general motor vehicle development.

How do you add hydraulic fluid to a hydraulic cylinder jack?

How to add hydraulic jack oil to an hydraulic jack (floor jack or bottle jack).First, don't open the Check Valves!The most common mistake with a floor jack is to open one of the check valves (or their covers) instead of actually finding the fluid reservoir plug. Be sure you have found the filler hole (which can be very tricky to find on an oily old jack -- it's probably a small rubber plug that might even be painted the same color as the rest of your jack, hiding on the housing of the main hydraulic ram, NOT on the base. The screw/bolt heads on the base are the check valves. If you open a check valve, the springs and check balls might come out under pressure, and your jack won't ever work again unless you can find them and put them back in the right places

If your jack needs oil, even after a couple of years, it probably also needs new seals. Adding oil might let you use it a while longer, but you should probably replace the seals (or if it's a cheap Chinese/Taiwanese jack, just get a new jack). American- or Japanese-made jacks are probably worth resealing. Please always use jack stands so when the seals really blow out you don't end up crushed.

You're probably going to just put jack oil in anyway (or maybe you did replace the seals and now you need to put jack oil in), so here's how to do it:

  1. Use Hydraulic Jack Oil (available at auto parts stores). Do not use brake fluid, which will turn the seals into useless cheese.
  2. Be sure you have found the oil reservoir hole, not one of the check valves. Do all the following work with the jack rightside up (and don't store the jack upside down or on its side).
  3. Clean the plug and jack body around the hole. Any debris in the oil can easily cause damage later.
  4. Release the valve/lower the jack (turn the jack handle counterclockwise).
  5. Unscrew or pry out the plug as appropriate. Fill the reservoir. A tiny funnel will probably make this a LOT easier).
    1. Close the valve and raise the jack slowly enough to not blast oil back out the hole. The reservoir level will go down, which is normal, and you shouldn't add oil now.
    2. Slowly lower the jack (again, just don't blast a bunch of oil back out the hole). Air bubbles may come out, causing a few drips of oil to come out too, in which case you should add oil until the reservoir is full, then go back to the previous step until you can lower the jack slowly without a bunch of bubbling.
  6. Bleed the air out of the system:
  7. Re-plug the filler hole, test out the jack, and you're done, although you should still replace the leaking seals if you didn't already.

Remember to always work on hard, level ground, use jack stands, chock the wheels, and set the parking brake.

Who invented lift?

The Roman scientist and inventor, Archimedes, was one of the first to invent the lift in 236 BC. His machine was for lifting heavy stones used for building. The modern lift was invented by Elisha Otis in the mid 1800's. Others had tried to design a lift, but failed because of the lack of brakes. Elisha Otis designed a safe braking system for the lift.

How do you repair a hydraulic barbers chair?

Repairing a hydraulic chair is a challenging task as the most common problem is that the chair won't hold the pressure in any longer, no matter what happens. Therefore one will have to look for a shop that sells replacement parts for a chair like that. Additionally, there are several companies who refurbish used equipment, so one can also check with them, whether they have any spare parts or if they are able to repair the chair for a small fee.

How do you replace a hydraulic pump in a john deere 4020?

Real pain. You must remove the fuel tank, radiator, and hydraulic oil cooler. There will be a plate that these items sit on that must be removed. Then disconnect the drive line coupler in front of the motor. You will need an 1 1/4" open end wrench to disconnect the oil lines on each side of the pump. There will be a small return oil line at the bottom of the pump to remove. There will be four 1/2" bolts about 4" long to remove from the front of the engine block that connects the pump frame to it. This unit is heavy! Suggest you wear leather gloves and use a lift or get help from a friend. Been there, done that!!

Where is the hydraulic oil filter on ih 424?

It's on the floor on the right side. If you follow a line that runs along the right side of the tractor beside your right foot you will see that it connects to a tube that goes into the metal case under the right corner of your seat.

On my tractor there is a rubber gasket with some clamps that keep the fluid from leaking out, but that can be removed so that I can disconnect the line sections and wiggle the portion that it under my seat and as I wiggle it I pull it toward the front of the tractor. It will come out of that case under the seat.

I haven't figured out where to drain the fluid so that it all doesn't come spilling out with the filter and onto the footrest.

What type of hydraulic oil is used in Massey Ferguson 65?

You may use two different hydraulic oil 1st is a 80-90 hydraulic oil available at the same store, also the recommended orginally was a mineral oil 90w . I have found both of these at your local tractor supply stores. The mineral oil is the least expensive running about $16.99 for two gallon container. The mineral oil will say on it for Ford 1952 through the 1960 years. It is the same again as the orginal mineral oil specified in the service manual.

Both of these oils fill the transmission combination rear axle and hydraulic. There is one fill hole as you set on the drivers seat and look down at the left side of shift handle about 5 inches over you will see the hex headed plug for filling. The dip stick is on the right side below the hydraulic handles and at about heal level above the running board again as you set on the seat. There is a hole passage way that connects the transmission differetial hydraulic together about 32 quarts of oil is needed to fill don't forget to check and don't over fill. Check this level occasionally especially if you are leaking some around the pto shaft output.

On mine, it's right next to the shifter. Yellow cap. I think it says "oli" which is a little confusing.
