Description

When your engine starts burning oil or you’ve lost compression, it’s usually time for new sleeves and pistons. If you’re seeing blue smoke on startup or the old girl just doesn’t have the power she used to, this complete kit gets you back to running strong. Nothing beats the satisfaction of a fresh rebuild that fires right up and runs smooth as silk.

What You’re Getting

  • Complete set with everything you need—sleeves, pistons, rings, pins, and retainers all in one box
  • Precision-bored sleeves that restore proper compression and oil control
  • Quality rings that seat properly and last through hard work seasons
  • Wrist pins and retainers built to handle the loads these engines put out
  • Standard 4-1/8 inch bore size for engines that haven’t been overbored before

Built for Real Farm Work

This kit fits a variety of agricultural diesel engines with the 4-1/8 inch bore specification. These are typically found in mid-range utility tractors that handle everything from loader work and hay operations to field cultivation and transport duties. Whether you’re running daily chores or putting in long hours during harvest, these engines need to deliver reliable power when you need it most.

Made to Last

Farm engines work harder than most folks realize—constant load changes, long hours, and conditions that would kill a car engine. This kit uses materials designed for agricultural use, with rings that handle the heat cycling and sleeves that maintain their finish even with extended oil change intervals. The precision manufacturing ensures proper fitment and long service life.

Good to Know

This is a complete teardown job that requires machine shop work for proper cleaning, inspection, and assembly. You’ll want to check bore condition, crankshaft journals, and deck surface before installing. Most rebuilders recommend replacing the oil pump and checking the cooling system while you’re this deep into the engine.
