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.
Install the lever on the main tube. Note the bearing clip fastens on the opposite side of the 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 inlet valve in the main 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).
