(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
