When your Allis Chalmers is losing power or running rough, worn intake valves are often the culprit. These valves take a beating from constant opening and closing—thousands of times per minute when you’re working. A bent valve or one that doesn’t seal properly can cost you horsepower and fuel economy, leaving you short on power when you need it most. This replacement intake valve gets your engine breathing right again.
What You’re Getting
- Precision-machined valve designed specifically for 301 CID 6-cylinder diesel engines
- Heat-treated construction handles the high temperatures and pressures of diesel combustion
- Proper stem diameter and length ensures correct timing and valve train operation
- OEM specifications mean it fits and functions just like the original factory part
Built for Real Farm Work
This valve is engineered for the 301 cubic inch diesel engine found in various Allis Chalmers tractors from the era when these orange machines were workhorses on farms across America. These 6-cylinder diesels were known for their reliability and torque, perfect for heavy field work like plowing, disking, and pulling implements through tough conditions.
Made to Last
Diesel engines run hot and work hard, so this valve is built from quality materials that can handle the punishment. The valve face is designed to seal properly against the seat, maintaining compression while standing up to the carbon buildup and heat cycling that comes with diesel operation.
Good to Know
Each 301 CID engine uses 6 intake valves total. When replacing valves, it’s smart to check your valve guides and seats at the same time—if one valve went bad, the others might not be far behind. A valve spring compressor makes the job much easier, and don’t forget to set your valve lash properly after installation.
