Loosen the nuts of V-band clamp (6) and V-band clamp (8) enough to allow the housings to rotate.Note: Excessive loosening of the housings will cause contact. Possible damage to the wheel may occur.Note: Before assembly, apply Loctite# 51008 C5A CO BSE A/S on the washer face and to the four threads of the exhaust manifold studs.
Mount the gasket (2) over the studs in the exhaust manifold.
Mount the turbocharger onto the exhaust manifold.
Tighten the four nuts (3) to 70 5 N m (52 4 lb ft).Use the following procedure to tighten the V-band clamp assembly.
