is over the hole. The adjustment knob can be held against the wood block allowing the roll pin to be driven into the 1/4” hole.

5)Remove the adjustment knob, the washer and O- ring.

NOTE: If the spacer and the spring set are stuck, this could indicate corrosion or possible saltwater intrusion into the adjustment tube and assembly, or that the adjustment tube is bent. The demand regulator should be removed from the helmet and cleaned and inspected, per this Chapter..

6)Carefully inspect all parts for corrosion, paying particular attention to threaded surfaces and the spring set. Clean and lightly lubricate parts per the instructions in this chapter.

NOTE: Carefully inspect the adjustment shaft to ensure it is straight, Check for damaged threads. Replace the adjustment shaft if any damage is found. Replace the O-ring.

7)Replace washer.

8)Replace the O-ring.

Inspect the washer and o-ring.

9)Inspect the inside of the adjustment tube on the regulator body to be sure there is no corrosion and the adjustment assembly can travel freely. Ensure the alignment tube is not bent or misaligned from impact, and that the threads are clean.

NOTE: If the inside of the adjustment tube is cor- roded, this indicates saltwater intrusion into the adjustment tube and assembly. The demand regula- tor requires removal from the helmet and cleaning per this Chapter.

7.7.5Reassembly of the SuperFlow 350 Regulator Adjustment System

Tools Required:

3/4 inch Open-end Wrench Attachment on Torque Wrench

Silicone grease, or oxygen compatible grease if used for oxygen service.

1)Lightly lubricate the piston and spacer and place the piston back in the regulator adjustment tube, fol- lowed by the spring set, and spacer.

2)Lightly lubricate the adjustment shaft end and threads, install the washer and the lightly lubricated O-ring on the adjustment shaft.

3)Slip the packing nut over the adjustment shaft fol- lowed by the adjustment knob.

4)Hold the shaft and rotate the knob until the pin holes line up. Use the inlet valve holder from the regulator tool kit to accurately align these holes. Us- ing a small hammer drive the retaining pin back into place, until it is flush with the surface of the adjust- ment knob.

5)Screw the adjustment knob assembly clockwise back into the regulator body leaving enough packing nut exposed to get the wrench on it.
