partial assembly of previous article above until
centered over the peg. Lower partial assembly
down onto peg until weight is resting on peg.
Place spacers near outside diameter of bonnet
(2) 180° across to stabilize partial assembly
from tipping over. See Fig ure 4. 48. Remove temporary eyenut.
49. Place wrench back onto stem nut (15). While
grasping anti-stem rotation tool, hammer rap
nut (15) tightly. Re move anti-rotation tool.
50. Place temporary eyenut back onto threaded
end of plug-stem assembly (7). Re-rig to
over head hoist.
51. Lift the internals subassembly (IS) and cyl in der
(3). Place a suitable thread sealant in three or
four places along the bottom shoulder of the
bonnet (2) where the bonnet (2)-to-body (1)
ring gasket (13) is located. Push the ring gasket
(13) into the sealant expecting the sealant to
hold the gasket (13) for fi nal as sem bly and
alignment; apply additional sealant if neces-
sary.
52. Swing lifted internals subassembly (IS) and
cyl in der (3) over the body (1) in its vise. Align
match marks and lower the internals sub as -
sem bly (IS) down wards into the body (1) cavity,
tak ing care to not damage the bonnet (2)-to-
body (1) ring gas ket (13). Remove over head
rig ging and tem po rary eyenut.
53. Prepare cylinder head (4) for its ring gas ket
(13) similar to ring gasket (13) for bonnet (2)
of previous article 33. , this subsection.
54. Align match marks and lower cylinder head (4)
down onto cyl in der (3) upper shoulder, taking
care to not damage cylinder (3)-to-cyl in der
head (4) ring gasket (13). Align the fl at edges
of the cylinder head (4) to be in the same plane
as the fl ange of the body (1) below by rotating
the head (4) as necessary.
55. Insert the four elongated cylinder bolts (16)
through the bolt hole of the cylinder head (4)
and downwards through the bolt hole of the
body (1) fl ange. Install nuts (17) on the bolts
(16) by rotating nuts (17) CCW (viewed from
above). Finger tighten all nuts (17).

41. Remove overhead support from eyenut. Re-
move eyenut.
42. Engage stem nut (15) with stem (7) end and
rotate nut (15) CW (viewed from above) about
two revolutions while restraining with tool to
prevent stem (7) rotation.
43. Remove the duct tape applied in previous ar-
ticle 32., this subsection. Grasp the cyl in der
(3) near its upper edge, and gently wiggle the
stacked internals sub as sem bly (IS) parts from
several directions.
44. Continue to wrench-tighten stem nut (15).
45. Place duct tape 360° around the cylinder (3)-
to-bonnet (2) joint.
46. Install temporary eyenut onto protruding
threads of plug-stem assembly (7). Install
cable, rope, etc., to over head hoist.
47. Raise internals subassembly (IS) with cyl in der
(3) above wooden peg. Remove peg. Lower
internals sub as sem bly (IS) and cyl in der (3)
down onto the fl at work surface.
WARNING
Never replace bolting (17, 18) with just any bolting if lost.
Bolt heads and nuts are marked with spec i fi ca tion iden-
tifi cation markings. Use only proper grades as replace-
ments.
56. Using a torque wrench, tighten the bolting
(16, 17) to the levels indicated in the follow-
ing table in an al ter nat ing, crossing pat tern in
1/4 revolution in cre ments.
