Rotate the fishneck so that the locking tab of the lock ring engages with the nearest groove on the flow tube.
Thread the jam nut down until it touches the lock ring. Tighten the chain vise and use a spanner wrench and cheater
bar to tighten the jam nut to 250 ft-lb.
Recheck the poppet spacing.
Install the spring lock clip onto the jam nut/wear sleeve retainer joint.
Install two 235 O-rings into the grooves on the OD of the fishneck and protect with electrical tape.

Apply DC 111 grease to all O-rings before installation, except where noted.
Apply anti-seize lubricant to all threads, except where noted.
Use the split clamp to clamp the OD of the shrouded stator in the chain vise.
a. Install a 032 O-ring into the groove on the upper bearing sleeve.
b. Thread the upper bearing sleeve assembly into the shrouded stator (left-hand threads).
c. Use a chain vise grip around the flats on the bearing surface to tighten the upper bearing sleeve assembly to 25 ft-lb.
Wrap a rag around the 2-inch case of the pulser and lightly clamp in the chain vise.
a. Install a 125 O-ring into the groove on the pulser’s intermediate case.
b. Slide the impeller (unshrouded) onto the pulser, vane-end last.
