Caution: If the inside diameter of the gear is damaged or has fretting in excess of a 3.175 mm [0.125-inch] wide
band, do not use the gear. Fretting or damage can result in gear movement on the camshaft nose which can cause
camshaft nose failure.
Visually inspect the camshaft gear for cracks, chipped, or broken teeth.
Inspect the bore of the gear for fretting or burrs.
NOTE: If the fretting, burrs, or raised material can not be removed with a fine crocus cloth, replace the gear.
Inspect the gear keyway for burrs.
Remove burrs with a fine crocus cloth.
NOTE: If the keyway is damaged or the burrs can not be removed with a fine crocus cloth, the gear must be replaced.
Measure the gear bore.
Replace the camshaft gear if it does not meet specifications.
Caution: If the area of fretting is longer than a 3.175 mm [0.125-inch] wide longitudinal band, do not use the cam-
shaft. Fretting or damage can result in gear movement on the camshaft nose and can cause camshaft nose
failure.
Visually inspect the camshaft nose in the gear fit area for fretting or burrs.
NOTE: If fretting or burrs can not be removed with a fine crocus cloth, replace the camshaft.
Measure the camshaft nose in the gear press fit area.
Replace the camshaft if it does not meet specification.
