A turbocharger bearing housing bracket is available.

Using the bracket prevents the turbocharger housing from rotating.

Remove the oil drain tube and the optional bearing housing bracket.

Remove the oil supply tube from the turbocharger.

Remove the intake and the exhaust pipes from the turbocharger.

Remove the charge air cooler piping from the discharge elbow.

NOTE: If the turbocharger mounting nuts do not loosen freely, split the nuts to avoid breaking a mounting stud.

Remove the four turbocharger mounting nuts.

Remove the turbocharger, and discard the gasket.

Inspect the turbocharger casings and replace if through cracks are found in the outer walls.

Cracks on the turbocharger mounting flange longer than 15 mm [0.6 in] are not acceptable.

Cracks on the turbocharger mounting flange must not reach the mounting holes.

Two cracks on the turbocharger mounting flange must be separated by 6.4 mm [0.25 in].

Through cracks at the dividing wall are acceptable and can be any length.

They must be separated by at least 12.5 mm [0.5 in].

Inspect the exhaust manifold gasket surfaces and the mounting studs for cracks or damage.

Replace any cracked manifolds or damaged mounting studs.

Inspect the turbocharger compressor V-band outlet and the discharge elbow V-band connection for dents or fretting.

Replace the turbocharger or discharge elbow if damaged so that the compressed air will not leak.

Apply a film of high-temperature anti-seize compound, Part Number 3823097, or equivalent, onto the turbocharger mounting studs.

Install a new mounting gasket, the turbocharger, and the four mounting nuts.

Tighten the mounting nuts.

Install the discharge elbow and clamp onto the charge air cooler pipe connection.

NOTE: Do not tighten the clamp until the elbow is installed on the turbocharger.

Install a new o-ring seal, the clamp, and the discharge elbow to the turbocharger.

Tighten the clamps.

Install a new gasket, oil drain tube, optional bracket and capscrews.

Tighten the capscrews.

Pour 50 to 60 cc [2.0 to 3.0 oz] of clean engine oil into the turbocharger oil supply opening.

CAUTION  Proper routing of the turbocharger oil supply tube is critical to avoid failure. Avoid any tube-to-metal contact. The inlet supply fitting must be oriented slightly off-vertical to allow proper alignment.

If installing a new turbocharger, install the male union elbow.

Install the turbocharger oil supply tube on the elbow.

Install the intake and exhaust pipes to the turbocharger, and tighten the clamps.

Operate the engine, and check for air and oil leaks.
