Engine News SEBD9397, May 2006, "New Inner Shields Protect the Exhaust Bellows". Disregard this article. Refer to the following article.Description of Change: New inner shields for the exhaust manifold are used. The new inner shields prevent wear on the bellows of the exhaust manifold. The new inner shields create a barrier between the exhaust bellows and the exhaust manifold shield.Adaptable To:
Illustration 1 g01250377
Typical exampleTwo inner shields are needed for each engine. One inner shield is used for each exhaust manifold. The new inner shields are used with the existing exhaust manifold shield. Table 1 lists the new part numbers.

(1) Existing exhaust manifold shield
Remove the soft shields from the exhaust manifold that is connected to the turbocharger inlet. Remove existing exhaust manifold shield (1) from the exhaust manifold.
Illustration 3 g01250376
(2) New inner shield
Install new inner shield (2) on the exhaust manifold.The new inner shields include locating tabs on each end in order to assist with locating the shield during installation. The locating tabs prevent the inner shields from sliding during normal operation.Note: Fasteners are not necessary for use with the new inner shields.
Install exhaust manifold shield (1) over new inner shield (2).
Reinstall the soft shields to the turbocharger inlet.
Reinstall the shields for the exhaust manifold to the exhaust manifold.
