Description

If your Allis Chalmers is starting to sound a little rough or you’re noticing smoke at startup, worn exhaust valves might be the culprit. These valves take a beating from the constant heat and pressure of diesel combustion, and when they start to wear, your engine loses power and efficiency. This replacement exhaust valve gets your 301 CID diesel engine breathing properly again.

What You’re Getting

Precision-manufactured valve with proper 30-degree face angle for optimal sealing
Built to handle the extreme temperatures and pressures of diesel operation
Direct replacement that fits right into your existing valve guides
Quality construction that meets or exceeds original specifications

Built for Diesel Power

This valve is engineered specifically for the 301 cubic inch, 6-cylinder diesel engines found in various Allis Chalmers tractors. These were solid, dependable power plants that could run all day in the field, and they deserve quality replacement parts when it’s time for an overhaul or valve job.

Made to Last

Diesel engines are hard on valves, especially the exhaust side where temperatures can reach over 1,500 degrees. This valve is manufactured from heat-treated steel that can handle those extreme conditions without warping or burning. The precision-ground seating surface ensures a tight seal against the valve seat.

Good to Know

Your 301 CID engine uses 6 of these exhaust valves, so if you’re doing a complete valve job, you’ll want to replace all of them at the same time. While you’ve got the head apart, it’s a good time to check valve guides and springs too—they all work together to keep your engine running smooth.
