Description
If you’ve noticed your Case IH tractor’s engine running rougher than usual, misfiring, or just not pulling like it used to, worn valve springs could be the culprit. These hardworking little components operate thousands of times per minute, controlling the precise timing of your engine’s intake and exhaust valves. When they start to lose tension, your engine can’t breathe properly, and you’ll feel it in reduced power and fuel economy.
What You’re Getting
- TISCO quality construction built to handle the constant cycling and stress that comes with real farm work
- Direct replacement springs that match factory specifications for proper valve timing and sealing
- Premium steel construction that maintains proper tension through thousands of operating hours
- Set includes enough springs for your specific engine rebuild or maintenance needs
Built for Real Farm Work
This valve spring fits Case IH tractors equipped with CDC-B series engines – the reliable 4-cylinder 3.9L and 6-cylinder 5.9L non-emission diesels found in many utility and mid-range tractors. Whether you’re running loader work around the farmyard, handling cultivation tasks, or putting in long days during planting and harvest, these are the tractors that handle the daily grind of farm operations. The CDC-B engines are known for their durability and straightforward maintenance, making them popular choices for farmers who need dependable power without complexity.
Made to Last
These springs are built to handle thousands of cycles and resist the temperature extremes and vibration that come with diesel engine operation. The steel construction maintains proper spring tension season after season, ensuring your valves seal correctly and operate at the right timing. Quality materials mean you won’t be doing this job again anytime soon.
Good to Know
Installation requires basic mechanical skills and proper valve spring tools – if you’ve got experience with engine work, this is a straightforward repair. Always replace valve springs as a complete set to ensure even performance across all cylinders. While you have the valve cover off, it’s a great time to check valve clearances and inspect other valve train components. Keep the springs organized by cylinder and position to avoid mix-ups during reassembly.
