Key Features

• Adjustable Bore Range: Designed to effectively remove piston ridges from cylinder bores measuring 3 to 5 inches (77 to 127mm) in diameter.
• Tungsten Carbide Cutters: Equipped with resilient tungsten carbide cutting blades for precise and consistent ridge removal.
• Fine-Thread Feed-Up: Features a fine-thread adjustment system that allows for smooth, incremental advancement of the cutting blades, ensuring a controlled and clean cut.
• No Readjustment Between Cylinders: A unique design allows technicians to transition between cylinders without the need for extensive readjustment, saving valuable time during engine overhaul procedures.

Applications

The GearWrench 2389 Engine Cylinder Ridge Reamer is an essential cylinder reamer tool for various automotive service tasks. It is primarily used during engine rebuilding and overhauls to remove the wear ridge that forms at the top of engine cylinders. This piston ridge remover prepares cylinder walls for new pistons and rings, ensuring proper fit and function. It is crucial to use this tool to eliminate the carbon ridge in cylinder bores before extracting pistons, preventing potential damage to piston ring grooves and piston lands. This specialized automotive cylinder ridge removal tool is suitable for both professional mechanics and experienced DIY enthusiasts engaged in engine reconditioning projects.

Benefits

• Protects New Components: Effectively removing the cylinder ridge prevents damage to new piston rings and piston ring groove lands during piston removal and installation, extending the lifespan of engine components.
• Enhances Engine Performance: Ensures that new piston rings seat correctly against a smooth cylinder wall, which is vital for optimal compression, reduced oil consumption, and improved overall engine performance post-rebuild.
• Streamlined Rebuilding Process: The tool’s efficient design and smooth cutting action facilitate a faster and more effective engine overhaul, minimizing frustration and labor time.
• Accurate and Consistent Results: Provides a precise and even cut, eliminating chatter and ensuring a uniform cylinder bore surface, which is critical for a successful engine reconditioning.
• Durable and Reliable: Constructed for resilience in demanding workshop environments, offering a professional-grade solution for consistent use in engine repair.
