Frequently Asked Questions – Cummins ISX Valve Camshaft 4059331
What engines is the 4059331 valve camshaft compatible with?
The 4059331 valve camshaft is designed for Cummins ISX Series engines, specifically ISX15, QSX15, ISG12, and ISGe diesel engines. This camshaft is compatible with multiple OEM part numbers including 4298626, 3680779, 4059170, 3680799, and M-4298626. The camshaft features 42.68″ length, tapered design, M12 x 12.5 thread, 7 journals, 12 valve lobes, and 6 injector lobes, making it suitable for ISX Dual Cam (DOHC) configurations requiring valve camshaft replacement.
What are the key features of the 4059331 new valve camshaft?
These new camshafts are made from forged billet steel, not cast iron and is made to meet or exceed OEM Specifications for duration, lift, and hardness 55rc. Our new ISX camshaft will increase power and performance that was lost due to worn or damaged lobes. Each camshaft is engineered to exceed OEM specifications and is thoroughly inspected to insure proper fit & performance. The forged billet steel construction provides superior durability compared to cast iron OEM camshafts, ensuring longer service life for your Cummins ISX engine.
How does this new camshaft compare to remanufactured ISX camshafts?
A new 4059331 valve camshaft offers several advantages over remanufactured alternatives: brand new forged billet steel construction with no previous wear history, engineered to exceed OEM specifications for duration and lift, superior hardness rating of 55rc for extended wear resistance, and no core charge required since it’s a complete new part. While remanufactured camshafts can provide good value, the new camshaft ensures maximum reliability and performance restoration for critical ISX engine applications where dependable operation is essential.
What are the signs that my ISX valve camshaft needs replacement?
Common symptoms indicating your Cummins ISX valve camshaft needs replacement include loss of engine power, rough idle, poor fuel economy, unusual engine noise or knocking, misfiring cylinders, and reduced compression. Worn camshaft lobes can cause improper valve timing, leading to decreased performance and potential engine damage. If your ISX engine experiences reduced power output, erratic operation, or mechanical noise from the valve train area, inspecting the valve camshaft for wear on the lobes and journals is recommended to prevent further engine damage.
Does the 4059331 camshaft require special installation procedures?
Yes, installing the 4059331 valve camshaft requires proper timing procedures and specialized tools to ensure correct valve and injection timing. The camshaft goes through a detailed inspection process prior to packaging and is well packaged for safe, secure shipping. Professional installation is recommended due to the complexity of ISX dual cam timing procedures and the need for precise measurement of camshaft journal clearances. Proper installation includes checking bearing clearances, setting timing marks, and following Cummins torque specifications to ensure optimal performance and longevity of your ISX engine.
