Description

When your trusty 4010 starts burning a little oil, losing compression, or just doesn’t have the power it used to, it’s time for an overhaul—and this kit gets you back to factory performance without breaking the bank. This basic in-frame kit includes all the major wear items you need to rebuild the top end of your 6-cylinder gas engine: sleeves, sleeve seals, pistons with 5 rings, pins, retainers, and a complete valve-grind gasket set plus oil pan gasket.

What You’re Getting

Standard 4-inch bore sleeves with 4-3/16 inch overbore also supplied for flexibility with different wear conditions
5-ring pistons designed for the 301 cubic inch displacement that provide excellent sealing and long life
Complete valve-grind gasket set covers all the sealing surfaces during your rebuild
Quality Tru-Power components engineered to meet or exceed original specifications

Built for Real Farm Work

This kit fits the John Deere 4010 series tractors that were the backbone of farming operations through the 1960s and beyond. These 6-cylinder gas engines were known for their reliability and smooth power delivery, whether you were pulling a 4-bottom plow, running a PTO baler, or handling loader work around the farmyard. Even decades later, many of these tractors are still earning their keep on farms across the country.

Made to Last

Tru-Power has been rebuilding agricultural engines for decades, and their components are built to handle the demanding conditions of farm work. The sleeves are precision-manufactured to restore proper cylinder bore dimensions, while the pistons and rings provide the compression and oil control your engine needs for thousands more hours of reliable service.

Good to Know

This is a basic in-frame kit, which means you’ll be working from the top of the engine without pulling it completely apart. It’s a great option when the bottom end is still in good shape but the cylinders and pistons need attention. You’ll want to have your machine shop check the sleeves for proper fit and finish, and consider having the head worked while you’re at it. Take your time with assembly—proper ring gap and torque specs are critical for a successful rebuild.
