Valve Guide Cleaning Reamers for Continental and Lycoming Engines

McFarlane offers special reamers in the necessary sizes to clean your Continental and Lycoming engine exhaust valves. Standard reamers manufactured for aircraft valve guides are designed to perfect the guide hole size when reaming new guides.

The patented McFarlane cleaning reamers have a pilot the same size as the valve stem. This properly sized pilot forces the reamer cutter to start straight and follow the correct valve stem path through the guide hole. Finally, a tool that is designed for the job!

While using standard reamers to clean valve guides, you probably have noticed that you have some valve guide metal in the reamer flutes afterwards. This metal is cut from the sides of the guide when hard carbon deposits displace the unguided reamer from the original guide hole, or the reamer was not started in alignment with the guide hole. Wavy or gouged guide holes cause premature carbon buildup, poor heat transfer, and early guide hole wear. Prevent damage to your valve guides by using McFarlane Cleaning Reamers!
