4. Remove exhaust pipe to manifold attachments.
5. Remove manifold to cylinder head bolts and nuts.
6. Remove intake and exhaust manifold assembly.
NOTE: It may be necessary to remove the generator rear
bracket to remove manifold assembly.
To separate intake and exhaust manifolds, disconnect
E.G.R. pipe and remove the four (4) bolts at the center of
the manifold.
NOTE: Whenever manifolds are separated, a new gasket
must be installed between the two sections. Install the
gasket with the perforated side toward intake manifold.

:
When assembling the manifolds
together, install the four bolts loosely. Place the
manifolds on a straight, flat surface and hold
securely during tightening and final torque. This
will assure the proper mating o f surfaces when
installing the manifold assembly on the head.
Failure to assemble manifolds in this manner could
result in failure o f manifolds fiom stress cracking
(torque bolts to 35 lb.
fi.)
When replacing exhaust manifold be sure insulator
gasket is in place between E.F.E. bracket and manifold (Fig.
6A2-11).
Replace
1. Install manifold assembly on cylinder head being sure
guides are in place.
