Required Tools:

1” Open end attachment on torque wrench

1/4 inch Flat Blade Attachment on Torque Screw- driver

3/8” Dowel Rod

1)Remove the screws and washers on either side of the regulator cover.

Remove the cover retaining ring and regulator cover.

Remove the lock clip from the interior of the regulator.

Unscrew the packing nut from the regulator body.

2)Unscrew the cover retaining ring.

3)Remove the cover and diaphragm. Inspect the diaphragm for holes or tears. If it torn or punctured it must be replaced. Inspect the interior of the regulator for foreign matter and remove if necessary.

4)Carefully insert the tip of a flat blade screwdriver in the slot at the top of the lock clip and slide the clip away from the regulator main tube.

5)Using the 1” open end wrench, loosen the pack- ing nut about 1 turn. While depressing the lever arm, grasp the flex knob and pull it straight away from the regulator body. This will remove all of the main components of the regulator valve mechanism as a single, easy to handle unit.

6)Unscrew the flex knob assembly from the main tube.

7)Loosen the packing nut on the flex knob and un- screw the packing nut. Hold the packing nut while turning the flex knob clockwise. You will notice the internal adjustment shaft will travel outward AWAY from the packing nut.

This shaft may not fall out so after about 10 revo- lutions of the knob. It will be possible to grab the chamfered tip of the shaft and pull it straight out from the assembly.
