NOTE: Refer to Fig. 9 for steps 17 to 22.
17. Lubricate the housing (18), spring (17), and guide
(16) with light, water-proof grease. Assemble the
housing and spring into the guide. Lubricate the
pin (19) and slide it into the housing. Slide these
assembled parts into the air manifold (20). Be sure
the pin (19) is aligned with the slot (C, Fig. 8) of
the air valve housing (5) before assembling the
rest of the air valve. Repeat for the other side.
18. Install the o-ring (15) on the retainer (14). Screw
the retainers into both sides of the manifold (20);
they should readily screw all the way into the
manifold by hand. If they do not, the parts are not
assembled correctly; inspect, and correct any
misalignment. Now firmly tighten the retainers
(14).
19. Place the gasket (30*), cap (29), and gasket (53)
on the air manifold (20). Check the parts list for
your model for the correct gasket (30*) to use. Be
sure these parts are oriented as shown in the parts
drawing for your model.
