Description

When your International Harvester 806 or 2806 starts showing signs of tired engine performance—maybe it’s burning oil, down on power, or hard to start on cold mornings—it’s time to consider an overhaul. These 361 cubic inch diesel engines were the workhorses of many farm operations, and with the right parts, they can be brought back to reliable service for years to come.

What You’re Getting

Complete cylinder sleeves and seals for a tight, leak-free rebuild
New pistons with rings, pins, and retainers for proper compression and oil control
Pin bushings to eliminate wear and ensure smooth piston operation
Valve-grind gasket set plus oil pan gasket for a complete seal job
Front and rear crankshaft seals to stop oil leaks at both ends

Built for Real Farm Work

This kit is designed for the 6-cylinder diesel engines found in International Harvester’s 806 and 2806 series tractors. These machines handled everything from heavy tillage work to grain harvest, and many are still earning their keep on farms today. The 361 CID engine with its 4-1/8 inch bore was known for its durability and torque.

Made to Last

This Tru-Power kit includes quality components that meet original specifications. The cupped-head pistons and precision-fit sleeves are built to handle the demands of diesel operation and farm work. While this is a basic kit without bearings, it covers the essential wear items that typically need replacement during an overhaul.

Good to Know

This is a basic overhaul kit, so you’ll need to source main and rod bearings separately based on your crankshaft measurements. It’s a good idea to have your machine shop check the crank for wear and determine what bearing sizes you’ll need. Most folks tackle this job during winter downtime when the tractor can be out of service for a few weeks.
