18. Apply Teflon tape to the threads of the lubrica -
tion line fittings (Figure 32). Install the fittings
onto the stuffing boxes.
19. Apply a light coating of petroleum jelly or
Anti-Seize to the mounting face of the power
end. This will greatly reduce the buildup of
corrosion.
20. Lift the new manifold onto the manifold
mounting studs (Figure 33).
21. Install and adjust the trunnion rod as follows:
Manifold Trunnion Adjustment
The trunnions in the manifold must be adjusted
such that the hinge rod supports the manifold to
allow the capscrews to be screwed in or out by
hand. The manifold holes need to be centered over
the tapped holes in the powerframe (or adapter
plate). This configuration will put the hinge rod in
a substantial bind and it will be bent down slightly
at the ends since it will be supporting the weight of
the manifold block. This centered position of the
manifold will also ensure proper operation of the
valves and seals at all pressures.
a. Remove two manifold bolts and install two
manifold mounting studs. Remove remaining
manifold bolts.
4200 / 3600 - p/n 54261
3000 - p/n 56742
b. Slide the manifold away from the powerframe
(or adapter plate) a few inches (Figure 34,
A). This will allow room to adjust the threaded
trunnions in the bottom of the manifold.
c. Screw both manifold trunnions (Figure 34, B)
in completely and then back them out approx-
imately 2-1/2 turns. Slide the manifold back
against the powerframe (or adapter plate).

CAUTION
Use two people to lift the manifold. The mani-
fold is heavy and failure to use two people may
cause serious injury.
