Removal & Installation: Camshaft: Inspection
If journal runout, lobe lift or oil clearance is not within specification, replace camshaft. See CAMSHAFT table under ENGINE SPECIFICATIONS. If necessary, remove camshaft bearings using Remover/Installer (J-33049).
CAUTION:
If camshaft bearings were removed, ensure oil holes are aligned during installation. Front and rear camshaft bearings have a different outside diameter than inner bearings. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS. If replacing camshaft, coat lobes with Prelube (1052365) prior to installation.
