Cleaning and Inspection
CLEANING
1. Remove camshaft sprocket from camshaft.
2. Clean the camshaft in an appropriate solvent and wipe it dry.
3. Remove light scuffs, scores, or nicks from the camshaft machined surfaces with an oil stone.
INSPECTION
Inspect the camshaft journals and lobes for scoring and signs of abnormal wear.
Lobe pitting, except in the general area of the lobe toe, is not detrimental to the operation of the camshaft. The camshaft should not be replaced unless
cam lobe lift loss has exceeded the specifications or pitting has occurred in the cam lobe lift area.
