Inspection

1. Place camshaft in "V" blocks. Measure bend. Bend limit is .001" (.025 mm). Check cam face condition. Remove minor burrs by grinding using oil stone. Check cam height and journal for damage or wear.
2. Measure outside diameter of camshaft journal and inside diameter of cylinder head journal to determine camshaft oil clearance. If clearance is not within specification, replace camshaft or cylinder head as necessary. See «CAMSHAFT»(ref-49461-S27686672992001011500000) under ENGINE SPECIFICATIONS.
3. Measure camshaft end play. If end play is not within specification, replace camshaft support.
