Description
When your diesel tractor starts losing power, running rough, or blowing smoke at startup, it’s often telling you the valves need attention. After thousands of hours opening and closing to control airflow and combustion, valve springs weaken, valve seats wear, and everything gets out of spec. This complete valve overhaul kit gives you everything needed to restore proper valve operation and get your engine running like it should.
What You’re Getting
- Complete valve set including both intake and exhaust valves for all four cylinders
- Heavy-duty valve springs that maintain proper tension for reliable valve sealing
- Valve keys (keepers) that secure everything in place under constant engine vibration
- TISCO quality components built to meet or exceed original equipment specifications
Built for Real Farm Work
This kit works on Ford New Holland 4-cylinder diesel engines found in utility tractors, compact tractors, and mid-size workhorses used across American farms. Whether you’re running a loader around the barn, cultivating fields, or powering a hay baler, these engines depend on precise valve timing to deliver the torque you need when the work gets tough.
Made to Last
These valve components are built from quality steel with proper heat treatment to handle the constant stress of opening and closing thousands of times per hour, with hardened contact surfaces that resist wear. Farm engines work in dusty conditions with long hours during busy seasons, and this kit is designed to handle that punishment.
Installation Notes
This is a job for someone comfortable with engine work, as you’ll need to remove the cylinder head and work with valve timing. Take your time setting valve clearances—too tight and you’ll burn valves, too loose and you’ll lose power and create noise. A good machine shop can handle the valve seat work if needed while you’re doing the overhaul.
