Removal & Installation: Camshaft: Inspection

Check camshaft journals for out-of-round condition. If journals exceed .001" (.025 mm) out-of-round, replace camshaft and lifters. Check camshaft end play. Standard end play is .0040-.0012" (.038-.127 mm). If not to specification, check camshaft end cover for grooves or wear. Replace as necessary.
Check camshaft lobe lift. Attach dial indicator with a ball/socket attachment to camshaft carrier or "V" block. Measure lobe lift. See CAMSHAFT SPECIFICATIONS under ENGINE SPECIFICATIONS. If lobe lift loss is more than .002" (.05 mm), replace camshaft. Check camshaft journal-to-bearing clearance. Standard clearance is .0010-.0040" (.025-.101 mm).

NOTE: Camshaft lobes are ground, hardened and tapered with high side of lobe toward rear of engine. This causes valve lifters to rotate.
