1. Remove the four or six relief valve cover bolts while holding
the cover down.
2. Lift the cover straight off. The stem and diaphragm assem-
bly will normally remain with the cover as it is removed. The
relief valve spring will be free inside the body at this point.
3. The relief valve seat is located at the bottom of the body
bore, and can be removed, if necessary, for cleaning. The
disc can be cleaned without disassembly of the relief valve
module. If it is determined that the relief valve diaphragm
and/or disc should be replaced, the relief valve module can
be readily disassembled without the use of special tools.
Note: The disc rubber is molded into the disc holder and is
supplied as a disc holder assembly.
4. To reassemble the relief valve, press the seat firmly into
place in the body, center the spring on the seat, and insert
the cover and relief valve module as a unit straight into the
bore. Press down on the cover to assure proper alignment.
Insert and tighten bolts.
Caution: If cover will not press flat against body, stem
assembly is crooked and damage can result. Realign stem
and cover before bolts are inserted.
NOTE: No special tools required to service Series 009 2
