Description
When your Allis Chalmers starts losing power or running rough, the intake valves are often the culprit. These valves open and close thousands of times per minute, letting the fuel-air mixture into each cylinder. After years of heat cycles and combustion deposits, they can get burnt, warped, or just worn out. A bad intake valve means poor compression and weak performance when you need power most.
What You’re Getting
- Precision-machined valve designed specifically for 226 CID 4-cylinder gas engines
- Heat-treated steel construction that handles combustion temperatures and pressure cycles
- Proper seating angle ensures tight seal against the valve seat for maximum compression
- Direct replacement part that installs with standard valve train components
Built for Real Farm Work
This intake valve fits Allis Chalmers tractors equipped with the 226 cubic inch 4-cylinder gas engine. These engines were workhorses in their day, powering everything from cultivating and planting to loader work and hay operations. Whether you’re restoring a vintage AC or keeping a reliable old machine running, proper valve function is critical for the power and fuel economy you expect.
Made to Last
Engine valves take tremendous abuse from constant opening and closing while exposed to combustion heat and corrosive gases. This valve is manufactured from quality steel with the proper metallurgy to resist burning and wear. The stem is precision-ground for smooth operation in the valve guide, while the head is built to maintain its sealing surface through thousands of operating hours.
Good to Know
Valve replacement requires removing the cylinder head and disassembling the valve train – it’s a job for someone comfortable with engine work. You’ll need four of these valves for a complete set since the 226 CID engine uses one intake valve per cylinder. While you’re in there, it’s smart to check valve guides, springs, and seats, and consider having the head professionally serviced for best results.
