5.14 Changing the valve seals on the lifting ram

Figure 5.25

NOTE!

When servicing the hydraulic system, the side sections and the seed drill should be low-

ered, with zero pressure in the respective hydraulic circuit

A

Remove hose (F), with care if there is any pressure left in the system.

B

Remove the seat (E), the guide (C) and the piston (A).

C

If leaking externally, change the O-ring (B) part no. 407021. If leaking internally change the
seal in the seat (E): First put the O-ring in place in the groove. Put the seal in hot water first,
and press it into a kidney shape to fit it.

NOTE!

The edge side of the seal should be turned to-

wards the piston. Use a blunt object to move the seal into place. Carefully insert the piston to
help restore the seal to its round shape.

D

Reassemble the valve. Do not forget the two rubber/steel washers.

The valve on the bottom of the lifting ram shuts off the oil flow from the ram after lowering to the
preset working depth.

Working depth is set with the depth stop (A), which actuates the valve via valve rod (D). If the
stop moves along the piston rod so that the working depth gradually increases, the valve is prob-
ably leaky.
