Question

Quizplus · Accepted Answer

The correct action when an injector cam profile on a camshaft shows visible deterioration of the hard surfacing is to replace the camshaft. This is because the hard surfacing is critical for the camshaft's performance and durability, and once it's deteriorated, polishing, machining, or repairing by metalizing won't restore the original integrity or performance levels.
