The only thing that causes hydraulic fluid to foam is air. The solution as to why your hydraulic system is creating air can be difficult. If the system has a hydrostatic drive , then there will be a charge pump( gear or georoler) which will always be working off of the hydrostatic pump in a vacumn state. This is where 90% of air introduction occurs. The easiest way to find the leak will be to notice any damp spots around the hydrostatic pump, usually at input shaft areas of any sort to the pump. The effect is a noisy, jumpy hydraulic action. Extended use while oil is aerated can cause damage to the pumps. If it is a regular hydraulic system them air will again be introduced on the inlet side of the pump, due to bad hoses, clamps, clogged inlet filter or low or overfull system
What else can I help you with?
When you put your car in reverse it does not move and when you put it in drive it still does not move your transmission fluid is very low would that be the problem or do you need a new transmission?
Low transmission fluid will cause the vehicle not to move. Try filling the fluid and see if it works. good luck
What would cause a car to rev high but have little acceleration when taking off?
The most common cause of a engine revving up above losing acceleration is a transmission problem. The transmission may be low on transmission fluid
What would cause the power steering fluid to leak and to start smoking from the back side of the engine?
It could be the p/s leaaking if you are loosing fluid. Otherwise, you just have to get back there and see what is leaking.
What can i use to fix hydraulic lifters?
I don't know what kind of lifter problem you are having.But I have had stuck lifters and lifters that would not pump up.This is the way I've fixed them before, some people laugh at this, but it worksOil is not a Hydraulic Fluid, Now Transmission fluid is.( some what )O That's right were working on HYDRAULIC lifters.Now change your oil and filter, Put 4 qts. of oil and the rest transmission fluidback in. If you can drive it, then drive it a lot. If not then just let it run for along time. I promise it will not hurt anything. It's an old trick and it works.Or aneven better thing to do if you are sceptical is to use LUCAS engine oil treatment use a full bottle(1L) every oil change an if it doesn't lift it then go back to the 1st awnser
Why would excessive transmission fluid be coming out of the overflow tube?
It is important to keep fluids from leaking from a car. Excessive transmission fluid would be coming out of the overflow because there is too much fluid in the transmission, or because the seal has become worn.
Will low hydraulic oil in trans for a Chevy s-10 2.2 cause clutch not to engage?
There is no hydraulic fluid in the transmission. However, there is hydraulic fluid in the clutch system. If the clutch fluid reservoir is empty it would cause clutch not to operate.
Where is the Hydraulic fluid cap on a case 730 tractor?
The hydraulic reservoir on the case 730 should be in about the same area as the case 630......on the right side of the tractor at the rear of the engine and on what would be the bell housing is a large cap screw type plug. There should be a dipstick not too far from it....you add hydraulic oil there, if it is a case-o-matic. If it is a standard transmission, then the dipstick and the plug should be on the rear of the tractor around where the seat bolts on.
What would cause the forklift mast to suddenly or slowly lower?
A loss of hydraulic fluid will cause a forklift mast to suddenly or slowly lower. The mast on a forklift is run by a system of tubing that is filled with hydraulic fluid. The mast might also fall suddenly if there is a break in the chain that holds the mast at a certain level or the chain is too loose.
Does a log splitter use hydraulic fluid or hydraulic oil?
Both! The gas engine would take oil then the log splitter that runs the hydraulics would take a specific hydraulic fluid. Its best to go by what the manufacture says
Why you use hydraulic jack oil only?
designed for hydraulic jack perhaps power steering fluid would work Brake fluid Ruins pump

Can you use brake fluid in hydraulic cylinders?
Brake fluid is a type of hydraulic fluid with very specific properties. You would have to check the compatibility of the particular fluid with the components in your system. This would include the cylinders, seals, hoses, and any other internal components exposed to the fluid. The best thing is to use the exact fluid that the system manufacture specifies.
Would a hydraulic hoist still work as well if the fluid was replaced with air?
No, a hydraulic hoist would not work as well with air instead of fluid. Hydraulic systems rely on the incompressibility of liquids to transfer pressure and lift heavy loads. The compressibility of air would reduce the system's efficiency and lifting capacity.
Why does your three point hitch not work when you unhook your front end loader?
Both are hydraulic. Often when you disconnect one hydraulic device you bleed air into the system... You might need to cap off the front end loader hydraulic connectors, bleed the air out and refill with hydraulic fluid. Another possibility is that you are simply low on fluid. Yet another, less loved cause, is a stuck priority diverter valve - that prioritizes hydraulic pressure when both devices are attached. Finally, not knowing your particular model - the possibility does exist that there is no diverter and that it runs off the same hydraulic line as the loader - in that case, the fix would be just to connect a line to the front end loader inlet, then connect the other line to the outlet (tractor side connections, clearly not the loader itself). Hope this helps.
What does transmission fluid do?
Transmissions are hydraulic just like your brake system or power steering system. Without transmission fluid you would have no hydraulic pressure for it to operate nor would you have lubrication. Trans fluid also has cleaners in it to clean your transmission as clutches, and gears wearaccumulate inside.
Would 80w90 gear oil work in a hydraulic jack?
No. Only hydraulic oil can be used in hydraulic jacks. Hydraulic oil is compressed (a requirement for use in hydraulic cylinders) so that there are no air or other gases dissolved in it. Before adding hydraulic fluid to the jack, be certain that the fluid has been sitting for at least 24 hours to avoid introducing air into the hydraulic fluid in the chamber.You should be able to purchase hydraulic oil (sometimes it will be labeled "Hydraulic Jack Oil/Fluid or Jack Oil/Fluid) in small or large quantities, inexpensively, at any auto parts store worthy of the name. It can also be purchased at some Walmarts and any heavy equipment supply stores.
Is hydraulic fluid flammable?
The most commonly used hydraulic fluids are oils, so yes they are flammable. However, most any fluid COULD be used as a hydraulic fluid depending on the system design requirements. So it really depends on exactly what type of fluid is being used whether it is flammable or not. Water is a "hydraulic fluid" and is not flammable. Under NFPA standards, petroleum-based hydraulic fluids are not "flammable" if their flash point is above 100o F (37.8o C); they would be "combustible". NFPA 1 (2009): 3.3.153.2 Definition of Flammable Liquid
