Description

When your diesel engine starts blowing smoke, losing power, or drinking more fuel than it should, you’re likely looking at valve problems. Worn valve seats, damaged guides, or weak springs can turn a reliable workhorse into a headache. This complete overhaul kit has everything you need to get your 3.9L back to running like it should—strong, clean, and dependable.

Complete intake and exhaust valve set engineered to handle diesel pressures and temperatures
Heavy-duty valve springs that maintain proper compression through thousands of hours
Precision valve guides for smooth operation and proper sealing
Valve keepers that lock everything in place and stay put under stress
One kit handles your entire 4-cylinder CDC-B series engine—no hunting for individual parts

Built for Real Farm Work

This kit is designed specifically for CDC-B series non-emission 3.9L diesel engines found in various agricultural and construction equipment. These engines power everything from compact tractors to utility equipment, handling daily chores like loader work, mowing, and pulling implements. Whether you’re running equipment season after season or putting in long days during harvest, this overhaul kit gets you back to reliable operation.

Made to Last

Farm equipment engines take a beating from dust, temperature swings, and heavy loads. These valves are built to handle the punishment with hardened stems and precision-machined faces that seal tight even after thousands of cycles. The springs maintain proper tension longer than cheaper alternatives, keeping your compression where it needs to be.

Good to Know

A valve job is serious engine work—plan on having the head checked for warpage and the valve seats professionally cut if needed. Clean everything meticulously, follow proper torque specs, and don’t skip the break-in period. If you’re doing the work yourself, take your time and measure twice. A good valve job can add years to your engine’s life.
