Camshaft Bushings for Cummins ISM

Bushing for Driver Support

The driver support bushing provides stability and reduces friction for the rotating camshaft. A worn or damaged bushing can cause misalignment, increased wear, or even premature failure of the camshaft itself. Replacing this component is essential during an overhaul or whenever signs of wear appear.

• Designed for Cummins ISM engines and compatible with related series like N14, QSM, and K19.

• Precision machined for a secure fit.

• Helps extend the service life of the camshaft and bearings.

Camshaft Bushing Set (Complete Engine)

For full overhauls, a complete camshaft bushing set ensures proper fit and balance throughout the entire camshaft system. This set includes all necessary bushings for the ISM, providing even wear distribution and smoother engine operation.

• Covers every camshaft bushing point for the ISM engine.

• Also compatible with L10, M11, and QSM engine families.

• Ideal for preventative maintenance during a rebuild.

Seals and Gaskets for the ISM Camshaft Assembly

Rocker Cover Housing Gasket

The rocker cover housing gasket prevents oil leaks around the camshaft’s rocker housing area. Over time, heat cycles and vibration can break down the gasket, leading to oil seepage and contamination.

• Designed for a perfect seal in Cummins ISM engines.

• Manufactured from high-temperature resistant materials.

• Maintains engine cleanliness and prevents costly oil loss.

Front Cover Seal Ring

Located at the camshaft front cover, this seal ring is critical to preventing oil leakage at the rotating shaft interface. A worn front seal can quickly lead to oil starvation and damage to other internal components.

• Precision fit for Cummins ISM engines.

• Built to withstand extreme pressure and temperature conditions.

• Recommended for replacement during camshaft servicing.

Rectangular Ring Seal

The rectangular ring seal provides additional sealing support in smaller camshaft assembly areas. Though compact, it plays an important role in maintaining oil control and system pressure.

• Designed to handle high compression sealing points.

• Perfect for Cummins ISM and select QSM engine applications.

• Prevents small leaks that can become larger over time.

Why Replace ISM Camshaft Components Proactively?

The camshaft system directly controls valve timing, fuel injection, and combustion efficiency. Even minor wear in bushings, seals, or gaskets can reduce performance, fuel economy, and reliability. Proactive replacement of these parts helps:

• Maintain consistent valve timing.

• Reduce friction and extend camshaft service life.

• Prevent oil leaks and contamination.

• Protect against catastrophic failures in marine and industrial applications.
