Cummins ISX Single Cam Overhaul Kits

The Cummins ISX Single Cam engine is a heavy-duty workhorse used worldwide in both industrial and marine applications. Over time, every ISX engine requires maintenance or a complete rebuild to restore power, reliability, and efficiency. Diesel Pro Power supplies complete Cummins ISX Single Cam overhaul kits designed for precise fitment to specific CPL configurations, ensuring a professional-grade rebuild every time.

Our overhaul kits are engineered to extend the life of your ISX engine, helping you restore compression, eliminate oil consumption, and return performance to factory standards. With 40,000+ satisfied customers worldwide, Diesel Pro Power has become the trusted choice for ISX parts, rebuild kits, and service components.

What Is a Cummins ISX Single Cam Overhaul Kit?

An overhaul kit is a complete package of replacement components designed to rebuild an ISX engine from the ground up. Instead of sourcing individual parts piece by piece, an overhaul kit ensures you have every essential component in one convenient solution.

Each kit includes:

• Pistons (1-piece or 2-piece, depending on CPL)

• Piston rings

• Cylinder liners

• Connecting rod bearings

• Main bearings

• Thrust washers

• Gaskets and seals

• Additional supporting hardware

By replacing these wear-prone components during a rebuild, operators can restore the ISX to like-new condition, improving horsepower, torque, and fuel economy.

Choosing the Right Overhaul Kit for Your ISX Engine

The Cummins ISX family has many variations, and not every kit fits every CPL (Control Parts List). Selecting the right kit depends on:

• CPL Number – Ensures correct piston type, liner size, and compression ratio.

• Piston Style – Some ISX engines use 1-piece pistons while others use 2-piece pistons.

• Application – Industrial, power generation, or marine use may determine supporting components.

At Diesel Pro Power, overhaul kits are clearly organized by CPL coverage, so you can select the correct option with confidence.

One-Piece Piston Rebuild Kits for ISX

Certain ISX Single Cam engines are equipped with durable one-piece pistons designed for high-compression operation. Rebuild kits for these engines include matched piston and liner sets, ensuring proper fit and balance.

Benefits of One-Piece Pistons:

• Enhanced durability under continuous heavy load

• Simplified installation compared to multi-piece assemblies

• Reduced risk of piston crown separation

These kits are ideal for CPL ranges such as 1771, 2440, 2441, 2627, 2628, 2629, 2631, 2632, 2803, 2814, 2933, 2934, 8046, 8047, 8048, 8083, 8242, 8243, 8244, 8255, 8257, 8258, and others.

Two-Piece Piston Rebuild Kits for ISX

Other ISX engines utilize a two-piece piston design where the crown and skirt are manufactured separately. These pistons offer flexibility for engines requiring different compression ratios or replacement of just the crown.

Benefits of Two-Piece Pistons:

• Lower replacement cost for piston crown wear

• Excellent thermal resistance under high exhaust gas temperatures

• Precision fitment for CPLs engineered with this configuration

Our two-piece piston overhaul kits are available for ISX engines with CPLs such as 2825, 8081, 8142, 8469, 8571, 8587, and 8588.

Supporting Components for ISX Rebuilds

Alongside overhaul kits, Diesel Pro Power offers a full selection of supporting rebuild components to complete the job properly. These include:

Piston Cooling Nozzles

Designed to spray oil on the piston undersides, these cooling nozzles prevent overheating and piston seizure. ISX and QSX engines require six nozzles per rebuild.

Crankshaft Seal Kits

Both front and rear crankshaft seals are available, each including seal and sleeve for a leak-free installation.

Filtration Components

• Oil Filters – Spin-on filters designed for ISX engines.

• Fuel Filters – Protect injectors from contaminants.

• Fuel/Water Separators – Prevent water intrusion that can damage injectors and pumps.

Service Tools

• Feeler Gauge Sets – For calibrating valve lash precisely.

• Piston Ring Installation Tools – Ensures proper ring seating during assembly.

• Oil & Fuel Filter Wrenches – Make servicing large-diameter filters quick and efficient.

Cooling & Monitoring Accessories

• Radiator Cleaners – Maintain efficiency of the cooling system.

• Temperature Switches – Protect your ISX from overheating.

• Mechanical & Electrical Gauges – Monitor oil pressure, coolant temperature, and more.
