6) Install the o-ring on the main tube. Lubricate with

Christo-Lube.

7) Install the o-ring on the adjustment nipple. Lubri-

cate with Christo-Lube.

8) Install the o-ring on the balance spacer. Lubricate

with Christo-Lube.

9) Install the bearing clip on the main tube. Note that

there is a locating pin on the clip that must engage the

correct hole on the main tube. The clip is correctly

positioned when it is on the side opposite of the de-

pression for the lever on the main tube.

10) Spread the arms of the lever just enough to install

it on the main tube.

11) Study the features of the inlet valve assembly.

There are four “wings” towards one end of the as-

sembly and a bore that creates the balance chamber on

the opposite end. The wings that align with the lever

arm are the two that have an additional wall for the

lever arm to bear on. The valve assembly should be

inserted into the main tube with these walls toward

the bottom of the regulator tube.

12) Using a clean wooden dowel rod, that has been

sharpened in a pencil sharpener and inserted in the

open end of the inlet valve, properly align and insert

the inlet valve into the main tube. If this is done

properly, the lever should lift up. If it does not, the

valve has not been inserted correctly.

13) While holding the inlet valve in position, pull

each arm of the lever outward just slightly until the

inlet valves moves further into the main tube, ap-

proximately 1/4 inch. The dowel rod should move in

a bit further to indicate that this has happened.

Install the o-ring on the main tube.

Install the o-ring on the inlet nipple.

Install the lever on the main tube. Note the bearing

clip fastens on the opposite side of the tube.

14) Release your pressure on the dowel rod. The

lever should fall back to its normal position against

the main tube. Push in gently on the dowel and the

lever should rise again. If this does not happen, the

inlet valve is not installed correctly and must be

reinstalled.

15) Remove the dowel rod and insert the spring and

balance spacer into the main tube. Make sure the

balance spacer is properly aligned inside the main

tube by pushing in on the end of the space to see

that it move inward (i.e., it engages the hole in the

inlet valve).

Install the inlet valve in the main tube.
