Measure the camshaft bearing in the engine block [Figure 70-100-35].
Measure the camshaft journal [Figure 70-100-36].
Calculate the oil clearance. If the clearance exceeds the allowable limit, replace the camshaft.
Measure the cam lobes at their highest point [Figure 70-100-37].
If the measurement is less than the allowable limit, replace the camshaft.
Put the camshaft in V-blocks. Install a dial indicator [Figure 70-100-38] on the camshaft bearing surface.
Turn the camshaft at a slow rate. If the misalignment exceeds the allowable limit, replace the camshaft.
