How do you add hydraulic fluid to a hydraulic cylinder jack?
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:
- Use Hydraulic Jack Oil (available at auto parts stores). Do not use brake fluid, which will turn the seals into useless cheese.
- 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).
- Clean the plug and jack body around the hole. Any debris in the oil can easily cause damage later.
- Release the valve/lower the jack (turn the jack handle counterclockwise).
- Unscrew or pry out the plug as appropriate. Fill the reservoir. A tiny funnel will probably make this a LOT easier).
- 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.
- 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.
- Bleed the air out of the system:
- 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.
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.

Where does the hydraulic fluid go in a barber chair?
There are two chambers an upper and a lower. If the chair is all the way down the fluid is in the upper chamber. When the barber selects the chair to go up the fluid from the top is forced through a metering valve to the lower chamber. As the lower chamber fills the chair moves up into the space that is vacated in the upper chamber.
What type hydraulic fluid do you use in a grasshopper lawn mower?
What kind of hydraulic fluid do I use in a grasshopper 721 1998 model with a kabota engine
The Hydros require Grasshopper Fluid, or Mobil DTE 26
Without a manual I will guess that it takes ISO68 Any oil labeled : DTE 26
AW ISO 68
ISO 68
AW68, which is the same as dextronIII trans fluid, pretty much a standard hydro fluid. check your informational sticker on the unit, it will be somewhere that wont get weathered like under a panel or seat, it will have the fluid capacities and types listed there.
Be careful though, many companies use regular 30 weight motor oil in their systems, and nowadays even more use green type fluids that are mineral oil based.

Can a AW32 hydraulic oil be replaced by an AW46 hydraulic oil?
The short answer is yes, if it will do the job required. Why was 32 chosen in the first place? A thicker oil will not flow as easily, especially under cold start-up or cold weather conditions. It will generate more heat as it goes through valves etc. which stresses components and seals. It will increase the load on the pump, be harder to filter, and potentially reduce the lubricating capabilities overall. It can be done, and is done by some when operating conditions permit. It can also shorten the life of your system if it's not done carefully.
