TURBOCHARGER REPLACEMENT - CONTINUED
INSPECTION - CONTINUED
Inspect compressor impeller blades and turbine wheel for damage. If damage is found, replace turbocharger.
Visually check turbine and compressor housings for cracks. If cracks exist on outer walls, replace turbocharger.
Visually check turbocharger intake and discharge for oil. If noted on turbine side, and oil discharge line is not restricted,
replace turbocharger. If oil is on intake side and no restriction is found, replace turbocharger.
Mounting flanges must be inspected after removal of turbocharger from engine.
Visually check mounting flange surfaces for cracks. Cracks longer than 0.6 in. (15.2 mm) or cracks which extend to
mounting holes are not acceptable. Cracks of any length, which extend through divider, are acceptable only if separated
by at least 0.5 in. (12.7 mm).
Ensure mounting flanges on exhaust manifold and turbocharger are clean and free of old gasket material.
Apply a thin coat of antiseize compound to exhaust manifold (16) mounting studs.
With assistance, install new gasket (17) and turbocharger (5) on exhaust manifold (16). Secure with four nuts (18).
Tighten nuts to 45 lb-ft (61 Nm).
