RE-ASSEMBLY PROCEDURE
1. Refit the protective housing (24) onto the body (1). Make
sure that all the ports and orifices in the body are aligned
with the holes in the protector.
2. Fit new lubricated O-rings to all the plugs (27 et 28).
Screw the plugs into all the ports except one HP port,
and tighten them using a 4mm Allen key.
3. Fit a new lubricated O-ring (16) on to the seat (15). Slide
the seat onto the tool (116236), with the sealing crown of
the seat against the plastic part of the tool. Push the
seat into the body to position it. Push on the plastic part
behind the tool to make sure that it is in contact.
Note : Before continuing, closely examine the
anti-extrusion washer (21). You will note that
it has a flat side and a concave side. For
correct assembly the concave side should be
against the O-ring, as shown in the picture
below.

4. Position the anti extrusion
washer (21) in the plug (20)
with its concave side facing
out. Lubricate the new
washer (22) well and fit it
into the plug, against the
washer (21). Visually check
that the O-ring is correctly
in contact. Lubricate the O-
ring again after it is in
place.
5. Fit a new lubricated O-ring (23) onto the plug (20)
6. Fit a new HP seat (18), with its blue face toward the
interior of the body. Check that the seat sits upright
inside the body. Position the spring (19) around the
seat.
7. Fit an 8mm Allen key into the plug (20). Engage the
plug into the regulator body. Push on the plug to
compress the spring, at the same time screwing the
plug into the body until it blocks. Using a torque wrench,
tighten the plug to 0.5 m.Kg.
