Mechanical pressure from the primary piston
Mechanical pressure from the primary piston
For measuring the flow of hydraulic fluid.
Various valves are used. 1 - hydraulic flow. 2 - adjustable hydraulic pressure. 3 - control of hydraulic flow.
Put a high pressure gauge within the range of circuit pressure in the pump circuit. Lock the final drive sprocket against the frame so that it can't move. Actuate the travel lever and record the reading on the gauge.
Is a closed circuit hydraulic system.
To send more pressure to the front wheels, where it is needed.
