Two inside exhaust manifold
studs (43), adapter (44), fuse
plug (38), three expansion
plugs (45), gasket (42), cover
(39), and two bolts (40) must be
in place to pressure check
cylinder head.
Install fabricated tapped blocking plate
(60), gasket (61), and two screws over
hole at end of cylinder head. Tighten bolts
securely.
Install four fabricated blocking plates (62),
four gaskets (63), eight bolts, sixteen flat
washers, and eight nuts over eight water
holes on fire deck, Tighten nuts securely.
Install scrap or dummy injectors to
properly seal injector tubes. Torque
injector clamp screws to 20-25 Ib-ft (27-34
N-m).
Connect an air supply line with regulator
to fabricated end plate (60). Pressurize
cyIinder head water jacket to 40 PSI (276
P
k a).
Immerse cylinder head in a tank of water
heated to 180-200°F (82-93°C) for twenty
minutes to heat head, observe water in
tank for bubbles which indicate a leak or
crack. Check for leaks at top and bottom
of injector tubes, oil gallery, exhaust
ports, fuel galleries, and at top and
bottom of cylinder head.
Relieve air pressure and remove cylinder
head from water tank. Remove air supply
line, regulator, end plate, scrap injectors,
