Precious Metals In-frame Overhaul Kits are engineered to deliver a reliable and high-quality rebuild that meets Caterpillar’s recommended overhaul practices. They include all parts necessary for a variety of repair options, from a basic repair to a complete in-frame overhaul. Kits can be purchased over-the-counter at any NMC Cat Machinery Parts Department location and come with a factory-backed, one-year parts warranty that covers Cat parts needed to correct the failure, including Cat parts damaged by the failure and labor needed to correct the failure (when work is performed at NMC Cat or an authorized Cat dealer).

In addition to being engineered to deliver a reliable and high-quality rebuild, these self-contained kits offer improved pricing; pre-packaged, genuine Cat parts for your convenience; ease of ordering and handling; and minimized selection errors.

We’re Ready with OptionsWith four cost-effective and simple-to-order overhaul options, Precious Metals In-frame Overhaul Kits cover 3306 as well as most heavy-duty Cat engines with serial number prefixes, and come in four levels: Bronze, Silver, Gold, and Platinum. Each succeeding level offers more value.

  • The BRONZE overhaul kit is your low-cost repair option and includes value-added components like Cat oil filters and fuel filters and components you might not think of replacing, such as exhaust sleeves and exhaust manifold studs. There is no core charge with the bronze overhaul kit.
  • The SILVER overhaul kit is suitable for a basic in-frame overhaul and is similar to competitive in-frame overhaul kits. It builds on the Bronze overhaul kit and also has no core charge.
  • The GOLD overhaul kit is suitable for a basic in-frame overhaul and includes the core parts from the Bronze kit and the added bonus of Cat Reman cylinder pack assemblies. Reman cylinder packs are beneficial because the rods, pistons, rings, and liners come preassembled, saving four to six hours of labor when compared to the Silver overhaul kit.
  • The PLATINUM overhaul kit includes all the components from the Gold kit plus a Cat Reman cylinder head assembly, Cat Reman fuel injectors, a Cat Reman water pump, and a Cat Reman oil pump. The Platinum overhaul kit optimizes engine performance and fuel economy and maximizes the built-in second or third life of your engine.
