1.
Insert the top two fluid cover nuts (18), threaded
end first.
2.
Thread the manifold bolts (29) a few turns into
the nuts (18), just to keep the nuts from rotating.
Repeat for the bottom two screws and nuts.
3.
Repeat steps 1 and 2 for the other fluid cover.
4.
Install the fluid covers with the top checks toward
the air inlet.
5.
Place two belleville washers (27), with the
washer closest to the nut having the rounded
side toward the nut and the other washer with the
rounded side away from the nut, then a washer
(26) on each tie bolt (24). Thread the tie bolts
(24) through the fluid cover retainer (9).
6.
Thread a fluid cover (6), the center section
assembly, the other fluid cover (6) and the other
