3. Inspect the poppet, spring, and guide for wear. Replace the spring and
guide if worn.
4. Apply a thin film of High Purity Goop to the sealing face of the gland
nut. Install the guide, spring, and ball into the gland nut. Apply a
coating of food grade grease to the check poppet to hold it in place
when installing gland nut in sealing head.
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 crowfoot/torque wrench combination, torque the gland nut to
176 Nm (130 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
