The Cummins V28 / VTA28 camshaft (OEM: 4073134) is a heavy-duty precision component designed for the V12 engine platform.
It features hardened journals to resist extreme loading in mining and marine applications.
In stock for global export.
We manufacture these camshafts using induction-hardened steel to ensure exceptional wear resistance on the cam lobes and journals. In the high-stress environment of a V12 engine, mechanical stability is paramount. Our precision-ground profiles ensure smooth valvetrain operation, helping your equipment maintain rated power output and fuel efficiency under constant load.

Failure often manifests as valve train noise, decreased power, or inconsistent timing. Since the VTA28 is a high-displacement V12, any wear on the camshaft lobes significantly affects combustion efficiency across all 12 cylinders. We recommend inspecting lobes for pitting or scoring during every major engine overhaul.
Our 4073134 camshafts are manufactured to match the original OEM material specifications and lobe profiles. By using induction-hardened steel, we ensure the unit maintains the same hardness and fatigue resistance as the original factory-supplied component, providing a reliable alternative for maintenance and repairs.
Always lubricate the cam journals and lobes with high-pressure assembly lube. Ensure the timing marks are aligned correctly with the crankshaft gear. We also highly recommend replacing the tappets (lifters) and inspecting the camshaft bearings to ensure the new shaft has a pristine environment in which to operate.
