Description
When you’re rebuilding one of those reliable Allis Chalmers diesel engines, worn valve guides can turn a good motor into a smoky disappointment. If you’re seeing blue smoke or oil consumption has gone up, there’s a good chance your valve guides are letting oil sneak past where it shouldn’t be. These precision guides get your valves seated properly again so your engine runs clean and strong.

Built for Real Farm Work
These guides fit the dependable 6-cylinder diesel engines that powered many Allis Chalmers tractors through their most productive years. Whether it’s a D17 or D19 that’s been your workhorse for decades, these engines were built to handle long days and heavy loads. When it’s time for a rebuild, you want guides that’ll keep working as hard as you do.
Made to Last
Valve guides take a beating from constant heat cycles and valve movement. These are made from durable materials that resist wear and maintain their dimensions even after thousands of hours of operation. They’re built to handle the thermal expansion and contraction that comes with diesel engine work.
Installation Notes
Installing valve guides requires the right tools and a bit of know-how—you’ll need a valve guide driver and possibly some machine work to get them seated properly. Most folks take this job to a machine shop unless they’ve got the equipment to do it right. Make sure to check valve stem clearances after installation.
