The foot valve adopts a manually controlled reversing valve. The function of the valve is divided into two-position three-way and two-position five-way. It has a small size, beautiful appearance, and panel installation.

Failures such as traveling sideways and traveling unilaterally have always been the most difficult problem for the owner of the excavator. In many cases, the root cause of the problem cannot be found and the inspection can only be stopped. In fact, many excavator working problems are caused by the failure of the foot valve. As long as you check carefully, you can find the root cause of the failure.

Fortunately, if the root cause of the failure is the foot valve, then the operator can handle the failure through disassembly and inspection, which can save a lot of money and make the excavator normal in the shortest time. Construction, the brick house will explain the disassembly steps for everyone.

Disassembly and assembly of walking foot valve

Breakdown essentials

Remove the protective rubber sleeve and remove the fixing bolts of the two foot valves.

Use a hammer and punch to remove the foot valve fixing pin and remove the cam.

Remove the fixing bolts of the two covers and remove the covers.

Remove the cover presser (similar to a plunger) and O-ring.

Record the position of the foot valve valve hole and the valve stem (check if there is no problem to reinstall the original position), and then remove the valve stem spring and O-ring.

After removing the gasket on the valve stem, fix the valve stem on the vise to remove the fixing bolts, and then disassemble the valve stem.

(Note that when fixing the valve post on the vise, a copper pad should be installed to prevent the valve post from being damaged, and the vise should not be tightened too tightly, otherwise the valve post will be deformed)

After removing the cam plug on the valve body, use a magnet to remove the steel ball.

Installation essentials

Place the steel ball into the valve body, and then apply thread glue to the nut to tighten. (Tightening torque is 2.5KGF.M)

When assembling the valve column, please pay attention to the installation sequence. After assembling, apply the threaded glue on the fixing bolts and tighten, then install the gasket. (Tightening torque is 0.5KGF.M) Install the O-ring and spring to place the valve stem into the valve body. After installing the cover on the valve body, apply a small amount of butter to the contact surface. (Tightening torque is 2.3KGF.M) After installing and fixing the foot valve fixing pin, install the protective cover. (Tightening torque is 1.0KGF.M)
