Description

When your trusty 4030 or 2840 starts showing signs of wear—low compression, oil consumption, or just doesn’t pull like it used to—it’s time for a complete engine rebuild. This comprehensive overhaul kit gives you everything you need to bring that reliable John Deere power back to life, so you’re not stuck borrowing the neighbor’s tractor during planting or harvest season.

Built for Real Farm Work

This kit is designed specifically for the 329 CID diesel engines found in John Deere 4030 series row-crop tractors and 2840 utility tractors. Whether you’re using your 4030 for heavy tillage work, running a corn planter, or putting long hours on your 2840 for loader work and general farm chores, this engine rebuild will restore the power and reliability you need.

Made to Last

Tru-Power builds their engine kits to handle the demands of agricultural service. The pistons are designed with the correct compression ratio for your engine, and all components meet or exceed original equipment specifications. This isn’t a quick patch job—it’s a complete restoration of your engine’s performance.

Good to Know

This is a major overhaul kit, so you’ll want to plan for some downtime and have a good workspace. Make sure to check your connecting rod length before ordering rod bolts—they come in different sizes depending on your engine. Take your time during assembly and follow proper torque specifications. A thorough rebuild now means years of reliable service ahead.
