how to replace lifter saturn 2002 1.9l sohc

First production motorcycle with a hydraulic disk brake would be the Honda CB 750 in 1969

Follow the manufacturers instructions.

4 Way hydraulic valves are often used with double acting cylinders. The valve usually has a handle that is used to change fluid direction. On the 4 way valve there will typically be 4 ports or openings for connections of hoses. Connecting hoses is done as follows: There will be an IN and OUT port and there will be an A and B port. (Different manufactures label differently so sometimes ports A & B are labeled 1 & 2 for example.) The in port is where the hose for fluid under pressure is connected. This may be from a hand operated or motor powered pump. The out port will be connected to the hose going to the fluid reservoir or tank. The A and B ports will be connected to the hydraulic cylinder. Now for the how it works part: Basically the handle controls a piston inside the valve. The piston is machined to allow fluid to run through it in different directions depending on the location inside the valve. There are two fluid paths inside the valve at the same time with fluid running two directions. One path is for the supply hydraulic fluid and one path is for the returning hydraulic fluid. When hydraulic fluid is pumped into the IN port and the handle is pushed one direction the fluid passes from the IN port and goes out the A port leading to one line or hose to the hydraulic cylinder. At the same time the valve allows fluid returning from the other hydraulic hose connected to the cylinder to come into port B and go out the OUT port on the valve back to the hydraulic tank. When the handle on the valve is pushed the opposite direction the fluid paths switch so the pumped fluid coming in the IN port goes out the B port to the hydraulic cylinder and fluid returns coming into the A port and goes through the OUT port back to the hydraulic tank. The 4 way valve allows fluid to run from the pump or (hydraulic fluid source) to the hydraulic cylinder in two different directions depending on the position of the handle so the cylinder can either be extended or retracted. When the handle on a valve is not pushed in either direction it is called a neutral or normal position. Some 4 way directional valves only allow fluid to pass when the handle is moved in one direction or the other while some allow the fluid to come into the IN port and go through to the OUT port when it is in the neutral position. The valves that allow fluid to pass from the IN to the OUT while in the neutral position are often used with powered hydraulic pumps. Once the pump is turned on the fluid begins to flow in and out of the valve until the handle is moved to direct fluid to the hydraulic cylinder.

It means how much oil is needed to make the motor turn one full revolution. If you have a 32 Cubic Inch Hydraulic Motor, you would need to push 32 cubic inches of oil through that motor to turn it once. Using the same hydraulic pump, a smaller cubic inch motor would cause higher speed, but less torque.

What's the make (manufacturer) and model? That information will be pertinent before this question can be answered.

Go to your local parts store or fuel jobber and get a can of Tractor Fluid or your dealer and get OEM fluid. About 50 bucks a can but a lot cheaper than a hydraulic pump failure. Good Luck!

It is by the brake master cylinder

You will need to remove Transmission, And you will see it in the bellhouseing. 4 bolts hold it in place.

HYDRAULIC PUMP ASSEMBLY LeBaron Convertible Review the complete service procedure before starting this repair. The convertible top on this model will raise slowly or make abnormal noise if the hydraulic fluid level is low. Disconnect the negative battery cable. Remove the sling well and floor cover from behind the rear seat. Disconnect pump wire connector and ground connection. Disconnect hydraulic lines from the pump assembly. Remove the motor pump assembly from the vehicle. The rubber mounts are pressed and locked into the mounting bracket. Pull up motor assembly to remove. To install: Position the motor assembly in the vehicle. Connect the hydraulic lines to the pump assembly. Attach the pump wire connector and ground connection. Install the sling well and floor cover behind the rear seat. Connect the negative battery cable. Fill the pump reservoir with Dexron

start your own car like it was a regular old day. while the car is still on disconnect the car battery and remove it, get a pair of jumper cables connect them each end to the battery wires (positive to positive and negative to negative). get your hydraulic battery you gotta put it on something other then the ground. connect the other end of the jumper cables to the battery and charge its that easy. if you don't get how i just explained it sorry.

no... one will float on the other and at hi temperatures or hydryrolic pressure will foam or create dangerous pockets in required pressure.

machine that takes advantage of the fact that pressure is sorted out equally in all directions possible in a liquid. :)

Hydraulics are fundamentally a means of transmitting force and movement from one point to another via a liquid which is free of gas and is therefore incompressible.

The other considerable advantage of this system is that pressure = force divided by area. This means that if the slave cylinder at the working end has twice the surface area on top of the cylinder than that of the master cylinder, then it is moved with twice the force but only travels half the distance. This means of generating a mechanical advantage whilst transmitting the force to a point remote from where it is applied makes it extremely useful.

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.

There is a skid plate on the bottom rear of the machine. Remove the skid plate and you can see the drain plug on the bottom of the tank. There is a second drain plug also forward more.

The hood hydraulic lifters run about $80 for the pair.

Right next to where to PTO shaft comes out of the back of the tractor there is a sight glass for the hydraulic fluid.

It is located beside the fill hole on the exterior of the machine

If the forks wont lift weight the seals in the piston may be worn..Turning up the pressure may not correct this problem..Most pressures in forklifts are factory set and should not exceed recommended values..There will be a relief valve near the pump or on the valve bank that will adjust the pressure. If the forks creep down especially with weight ...the seals are bad. If its just to lift something heavy and the forklift wont lift it, this item just might be over the forklifts capacity. If there is Water in the oil this can cause probs too.

Most simply, a small cylinder and piston, a larger cylinder and piston, and some tubing to connect the two.
