6. Using the 5/16 Allen wrench, loosen and
remove the stem seat (9), then using the pick
remove the O-ring (10), and body seat (11).
7. Discard the three old O-rings, then clean all
the parts and blow or air dry. After drying,
carefully inspect all components, for signs of
damage and contamination. Re-clean as
necessary.
Reassembly
1. Lightly lubricate the three new O-rings (10, 7,
6), and set aside.
2. Install the body seat (11), O-ring (10), then
using the blunt end of the dowel, press down
on the O-ring, and body seat to fully seat the
O-ring around the body seat.
NOTICE
The relief valve can be overhauled in place,
however for best results it is easiest to remove
the relief valve from the manifold if performing
an overhaul, so that the valve can be properly
cleaned.
NOTICE
The O-ring can be difficult to remove and
requires manipulation with the O-ring pick and
the 6/32” Allen wrench from the bottom end of
the bonnet.
