The Cummins K19 / KTA19 / QSK19 camshaft (OEM: 3066877) is a precision-engineered component for the legendary K-Series heavy-duty engine.
It features deep induction hardening to withstand the extreme stresses of mining and marine applications.
In stock for global export.
Our manufacturing process focuses on critical surface hardness. By using high-strength steel with induction-hardened lobes and journals, we mitigate common issues like surface pitting (spalling) that often plague overworked K19 engines. Choosing our aftermarket camshaft ensures that your heavy-duty equipment maintains optimal fuel efficiency and power delivery during its next major rebuild.

The K19 is a high-output engine. The most common issues are lobe pitting due to oil contamination and bearing journal damage caused by oil pressure loss. Routine oil analysis is highly recommended to monitor metal content and prevent camshaft failure.
Our 3066877 camshafts are manufactured to meet or exceed OEM steel metallurgical standards. By utilizing deep induction hardening on the lobes, we provide the surface hardness necessary to prevent early surface degradation, making them an excellent cost-effective alternative for engine rebuilds.
Yes. Because the K19 engine is massive and carries heavy tolerances, always check the camshaft bushing clearances before final installation. Use high-quality assembly lube on all lobes and journals to prevent “dry starts,” which can cause immediate, irreversible damage to new camshaft surfaces.
