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.
