3. Inspect the poppet, spring, and guide for wear. Replace the spring and
guide if worn. Replace the poppet ball if it has dull appearance.
4. Apply a thin film of High Purity Goop to the sealing face of the gland nut.
Install the guide, spring, and poppet into the gland nut. These parts should
be installed dry, ie, without grease.
5. Apply High Purity Goop to the gland nut threads. Install the gland nut into
the sealing head. The gland nut should be hand tightened until there is a
gap of 5mm (0.20”) between the gland nut and sealing head. No threads
should show. If the gap exceeds 5mm (0.20”), then the poppet has slipped
out of place, and the parts must be removed, inspected and reassembled.
6. Using a 30mm (1-3/16”) crowfoot/torque wrench combination, torque the
gland nut to 88 Nm (65 ft-lbs.).
7. Reconnect high pressure and low pressure piping, collar and quick
disconnects per Section 7.2.1. Operate waterjet pump to verify HP fittings
do not leak, and that the HP water signal is normal (indicative of normal
check valve operation).
