Caterpillar C15 Out-of-Frame Engine Rebuild Kit (MCOH3466615), New

Complete Out-of-Frame Rebuild Kit for Caterpillar C15 Engines

When your Caterpillar C15 diesel engine shows advanced wear – such as low compression, excessive oil consumption, loss of power, or major internal wear – a full out-of-frame rebuild kit is the best solution to restore performance and maximize engine life. This new Caterpillar C15 out-of-frame engine rebuild kit includes only brand-new components engineered to meet or exceed OEM specifications, giving you a complete overhaul solution you can trust.

Out-of-frame kits are designed for complete engine teardown and rebuild, where the engine is removed from the frame for a thorough inspection and replacement of core parts – ideal for engines with major internal damage or wear.

Why Choose This Caterpillar C15 Rebuild Kit?

New Premium-Quality Components

Unlike some OEM kits that may include reused or remanufactured parts, this rebuild kit comes with 100% new components manufactured in an ISO 9001 certified facility. Each part is designed with precision to ensure reliability, strength, and longevity under heavy-duty diesel operating conditions.

Built to OEM Specifications

All parts in this out-of-frame rebuild kit follow strict OEM tolerances, ensuring precise fitment and dependable performance. This means easier installation, better sealing, and improved engine operation compared to worn or mismatched old components.

Extended Warranty and Support

This kit typically comes with a 2-year unlimited mileage parts and labor warranty, providing peace of mind and long-term protection for your engine rebuild investment. In addition, you’ll have access to ASE-certified technical support to assist you from purchase through installation.

What’s Included in the Kit

This comprehensive out-of-frame rebuild kit includes a full suite of new parts needed for a total engine overhaul. Typical contents include:

  • Multiple cylinder kits (liners, pistons, rings, pins & retainers)
  • Complete gasket and seal sets
  • Rod bearings and main bearings
  • Thrust plates
  • Cylinder liners and o-rings
  • Pistons, piston crowns, pins, and retainers
  • Water pump seal kits and oil cooler seals
  • Turbocharger gaskets and other essential sealing components

Every piece in this kit is crafted with high-quality materials to restore engine geometry, compression, and reliability – the foundation for smooth operation and long engine life.

Benefits of an Out-of-Frame Engine Rebuild

Restore Full Engine Performance

When internal wear reaches a critical level, a partial repair or in-frame rebuild may not be enough. An out-of-frame rebuild ensures worn or damaged core components are replaced, helping restore compression, smooth combustion, and optimal power output.

Extend Engine Life

Replacing key engine parts like bearings, liners, and pistons with new components reduces wear and friction, helping your engine run more efficiently and last longer under heavy use. 

Cost-Effective Alternative to New Engines

A complete out-of-frame rebuild using new parts often costs significantly less than purchasing a new engine while delivering similar performance and reliability – a major advantage for high-hour trucks or fleet vehicles.

Zero Core Charge

This rebuild kit comes with zero core charge, eliminating the hassle and cost of returning old parts – saving time and simplifying your purchase process.
