See, in this article, CAMSHAFT LOBE SPECIFICATIONS table.NOTE: For additional camshaft specifications, see CAMSHAFT SPECIFICATIONS table under ENGINE SPECIFICATIONS.NOTE: Camshaft bearings are NOT replaceable. If not within specification, replace cylinder head and/or camshaft.
- Measure camshaft bearing journals and cylinder head bores. See Figure. Subtract camshaft bearing journal O.D. from cylinder head bore I.D. to obtain oil clearance. If clearance is not within specification, replace head and/or camshaft. See, in this article, CAMSHAFT SPECIFICATIONS table under ENGINE SPECIFICATIONS.
