Set the tool aside.Indexed FeatureNOTE: The valve body and box bottom are both indexedwith four flat surfaces where their inlet portions mate.Closely examine the features of each part to become familiarwith their correct orientation before performing the next step.16. Insert the inlet end of the valve body through the roundopening in the adjustment side of the box bottom. Rotate thevalve body until the large hole in the center of the tube isfacing towards the vane inside the outlet boss, and the indexed(squared) shoulder is correctly aligned with the indexedopening of the box bottom (see Fig. 16). Gently press thevalve body into place, until it is securely seated and theindexed shoulder is flush with the surrounding outer surfaceof the box bottom.Indexed FeatureFig. 16 - Valve Body / Box Bottom AlignmentCAUTION: Do not apply undue force to press the valve bodyinto place. Doing so may cause the O-ring(20) to bind upand become unseated, which may allow water to leak intothe box bottom (see Fig. 17). If bind up occurs, remove thevalve body and check to ensure that the O-ring has beendressed with a sufficient amount of silicone grease.17. Thread the hex nut(13) clockwise by hand onto the inlet ofthe valve body, with the shoulder side facing in towards thebox bottom. While holding the box bottom secure, apply atorque wrench with w' crow-foot to tighten the hex nut snugto a torque measurement of 45-55 inch-lb.’s.18. Before proceeding, it is important to become completelyfamiliar with the relationship of the lever(5) and the leverretaining sleeve(27). Closely read the instructions given insteps a-c before performing any further assembly. Carefullyfollow each step, and refer to the corresponding illustrationsfor further clarification.a. Stand the retaining sleeve vertical, so that the slotted endfaces up. Closely examine the sides of the lever retainingsleeve(27) to identify the four open channels which areoffset from each other by 90 degrees. Locate the widestchannel, and then the channel which faces opposite of it by180 degrees. Closely examine the inner barrel of thesleeve around this channel to see that it contains a steppedrail which engages with the lever (see Fig. 18a).b. Closely examine the lever to see that it contains a smallgroove beside the notch. Position this groove above therailed channel of the retaining sleeve, and lower the leverinto place as shown in Fig. 18b. This will illustrate howthe railed channel of the sleeve rides back and forth overthe grooved feature of the lever as the adjustment knob isturned in and out.c. Examine the other two opposing pin guides to see thatthey are narrower and uniform in size.PinGuideFig. 17 - Valve Body O-ring Bind-UpNotchGrooveRailFig. 18a - Lever Retaining Sleeve FeaturesFig. 18b - Retaining Sleeve/ Lever Engagement© 1997 U.S. Divers Co., Inc.
