Piston Packs

To help reduce overhaul time and costs, Caterpillar has developed remanufactured piston packs for 3116 and 3126 engines. Reman piston packs feature an assembled connecting rod, piston, and piston rings (rings are compressed inside an installation tool). Plus, Cat Reman piston packs feature performance-matched, genuine Caterpillar parts to help you get the most out of your engine.


Cat Reman piston pack components for 3116 and 3126 engines are remanufactured to same-as-new quality for superior performance and reliability. The connecting rod at the heart of a Cat Reman piston pack is checked for cracks, bend and twist, and all other critical features. The crank end is resized to new part specifications. Each Cat Reman piston pack also features:

  • Rebushed or replaced pistons (depending on design)
  • New piston rings
  • New or remanufactured piston pin
  • New piston retainers
  • Installation tool hardware


Exchanging Cat Reman piston packs is simple and requires no special tools. To receive a full refund, a Cat piston pack core must:

  • Have an acceptable Caterpillar part number
  • Be fully assembled and complete
  • Have a matched rod and end cap
  • Have an unbent, unbroken connecting rod

>Remember to return your Cat piston pack core in its original carton.
