Description
When you’re overhauling that Allis Chalmers diesel or dealing with a valve that’s been knocked around by years of hard work, you need parts that’ll get you back in the field fast. These exhaust valves are what came in your tractor originally—built to handle the heat and pressure of diesel combustion without giving up on you during busy season.
What You’re Getting
- Precise fit for the 426 cubic inch 6-cylinder diesel found in classic Allis tractors
- Heat-treated steel construction that stands up to diesel exhaust temperatures
- Proper sealing surfaces that keep compression where it belongs
- Set of 6 valves—exactly what you need for a complete engine rebuild
Built for Real Farm Work
This valve set fits the 426 CID diesel engines that powered some of Allis Chalmers’ most dependable tractors. These were the workhorses that pulled plows, ran balers, and handled loader work day in and day out. The 6-cylinder diesel gave these machines plenty of torque for heavy pulling while staying fuel-efficient enough to make sense on the farm.
Made to Last
Exhaust valves take the worst beating in any engine—they’re opening and closing thousands of times per hour while dealing with 1200-degree exhaust gases. These valves are manufactured to OEM specs with the right metallurgy to handle that punishment without warping or burning.
Good to Know
If you’re doing a valve job, now’s the time to check your valve guides and seats too. A good machine shop can tell you what needs attention. Don’t forget new valve springs while you’re at it—they’re cheap insurance for keeping these valves sealing properly for years to come.
