Removal
Remove the cylinder head, camshaft chain sprocket and oil pan. Turn the engine over, placing it on the surface mating with the cylinder head. Turn the camshaft a few revolutions to disengage the tappets from the camshaft lobes.
Before removing the camshaft, check its axial play (see Fig. 4D.46).
Unscrew the two mounting bolts and remove the camshaft thrust plate. Remove the camshaft from the front end of the engine. Remove the tappets from the cylinder block and arrange them in the order of installation in the engine (see Fig. 4D.47).
Examination
Check the camshaft bearing journals and cams for wear or damage. Examine the inner surfaces of the camshaft bearings for damage or wear. If the camshaft bearings fail, they must be replaced at a service station. If the axial play of the camshaft exceeds the permissible values, the thrust plate must be replaced.
Check the condition of the tappets. If worn, they must be replaced.
Installation
To install the tappets and camshaft, turn the engine over. Lubricate and install the tappets in their places in the engine block.
Lubricate the camshaft bearings and thrust plate, then install the camshaft into the engine block.
Secure the camshaft with a thrust plate and tighten the mounting bolts to the specified torque. Check that the camshaft rotates easily and that the camshaft play is within acceptable limits.
