Unscrew and remove the lock screw (pos 23) and
o-ring (pos 78) from the swivel sleeve.
Tool: Hexagon wrench No. 5
Put a small container underneath the coupling and
start twisting the svivel sleeve, so the balls drop
out, into the container. Placing a tank unit in the
hose unit will make it easier to twist. Save the 48
balls for reassembling later.
Remove the swivel sleeve by pulling out the hose
unit body with the inner package. If the swivel
sleeve cant be removed, there might be some balls
left inside. Try turning back and forth again to get
out the remaining balls.
Remove the shaft and rollers (pos 15 & 44) for
piston guide, by applying slight pressure to the
driving plate package so that it moves down, until
the driving plate package is released from the
rollers.
The ring surface on the top of the driving
plate is a sealing surface. Press down the
piston only, the driving plate will follow.
Turn the driving plate to the position where the driving
plate heels are coming free from the rollers. It could
be necessary to release the package from the press
force.
Remove the driving plate package from the hose unit
body.
(There are different ways to remove the driving plate
package. If yours is not possible to remove, ask your
sales representative for an updated instruction)
