Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Ensure that the inside of the cylinder block is clean. Inspect the camshaft bore for metal burrs. Put a thin film of clean engine oil on the inside of the camshaft bearing bores and on each camshaft bearing prior to installation.Note: Two different camshaft bearings are used. Install the wider camshaft bearings in the front and rear camshaft bores. Install the narrow camshaft bearings in the inner bores.
