Description
When your Allis Chalmers starts losing power or won’t hold a good idle, weak valve springs might be the culprit. These little coil springs don’t look like much, but they’re working overtime—opening and closing your intake and exhaust valves thousands of times per minute. When they start to sag or lose their tension, your engine can’t breathe properly, and you’ll notice it right away in how the tractor runs.
What You’re Getting
- Set of valve springs that fit both intake and exhaust valves on your gas engine
- Proper spring tension to ensure valves seat completely for good compression
- Heat-treated steel construction that handles the constant cycling without fatigue
- Direct replacement for original equipment—no modifications needed
Built for Real Farm Work
These springs are designed for the gas engines found in a wide range of Allis Chalmers tractors from the vintage iron days. Whether you’re running an older utility tractor for general farm chores, hay work, or keeping a classic machine alive for parades and shows, proper valve spring tension is critical for reliable operation and good performance.
Made to Last
Valve springs take a beating—they’re constantly flexing under heat and pressure. These replacements are built with the right steel alloy and heat treatment to maintain their tension over thousands of hours of operation. They’ll keep your valves seating properly so your engine maintains good compression and runs like it should.
Good to Know
This is definitely a job for someone comfortable with engine work, as you’ll need to remove the valve cover and work with valve train components. If you’re doing a valve job or rebuilding the top end, now’s the perfect time to replace all the springs while everything’s apart. Always check valve clearances after installation.
