Caterpillar C12 Camshaft Problems, Symptoms, and Replacement

If your Caterpillar C12 is losing power, running rough, or showing signs of valve train issues, the camshaft may be part of the problem. A worn camshaft can affect valve timing, engine efficiency, fuel economy, and overall performance. Left too long, what starts as a drivability issue can turn into a much larger repair.

Because the camshaft plays such a major role in how the engine breathes and performs, wear in this area should never be ignored. If you are already narrowing down the repair, our Caterpillar C12 Camshaft is a good place to start, and you can also browse more Caterpillar Engine Parts if the repair involves other related components.
