The filter regulator is re-assembled in reverse order.
First the components of the lower assembly are
replaced in the housing. The upper assembly is then
put back together.
If new seals are used during re-assembly,
thoroughly grease them prior to installation.
Assembling the bottom part
Insert the O-ring Ø 31x2 [9] in the housing.
Insert the valve piston [10] and the pressure spring [11]
in the housing.
Set the insert [12] in the housing [8] using needle-nose
pliers (while doing this, make sure that the pressure
spring [11] is centered; lock the insert in place by
turning it to the right).
Insert the filter element [13] into the mount for the baffle
in the receptacle [14].
Screw the receptacle [14] back into the housing [8];
while doing this, center the filter element and tighten the
receptacle [14] by hand.
Assembling the top part
Insert the seal [7] in the hole of the housing so that the
sealing lip points in the direction of the housing bottom
(carefully insert it so that the sealing lip is not
damaged).
Center the valve piston [10] (already mounted in place).
Pull the piston [6] out of the housing [8]. While doing
this, make sure that the valve piston [10] and the piston
[6] are properly centered.
Insert the spring [5] onto the centering spigot of the
piston [6].
Screw the upper assembly [3] onto the housing [8]
(while doing this, secure the set screw) and securely
tighten the upper assembly [3].
