11. Carefully place the bottom cover (201) on the cylin-
der (211), sliding the rod (206) through the bearing
(202). The manifold surfaces of the top and bottom
covers must align. Be sure the shield (212) is in the
groove on both the top and bottom covers.
12. Install the tie bolts (210) hand tight.
13. Install two gaskets (214) on the manifold (215), and
install the manifold. Torque bolts to 95-105 in-lb
(11-12 N•m). (The manifold is reversible for ease of
placement of the muffler or the remote exhaust.)
14. Align the pneumatic valve gasket (216) on the mani-
fold (215), then attach the pneumatic valve (217).
15. Tighten the bolts (210) halfway. Work in a
criss-cross pattern while tightening the tie bolts.
Check that the shield remains in the grooves on
both covers. Continue tightening the bolts in pattern
and torque to 25-30 ft-lb (34-40 N•m).
16. Lubricate and install the pilot valves (219) in the top
and bottom covers. Torque to 5-105 in-lb (11-12
N•m).
17. Reinstall the mufflers (18).
