Engine Cylinder Flex-Hone(R) - Heavy-Duty - 3-1/2In - GearWrench

Specifications

• Manufacturer: GearWrench, Apex Tool Group, LLC
• Model Number: 2491
• Product Type: Engine Cylinder Flex-Hone
• Diameter: 3-1/2 inches (88.9 mm)
• Duty Rating: Heavy-Duty

Key Features

• Advanced Flex-Hone Technology: Utilizes abrasive globules permanently bonded to flexible nylon filaments, ensuring the tool is self-centering and self-aligning within the bore.
• Heavy-Duty Construction: Engineered for durability and extended operational life, designed to withstand demanding engine reconditioning tasks.
• Precision Sizing: Specifically designed and manufactured for optimal performance on 3-1/2 inch (88.9 mm) diameter engine cylinders.
• Consistent Surface Finish: Creates a uniform cross-hatch pattern and a critical plateau finish essential for proper piston ring seating and oil retention.

Applications

• Engine Cylinder Reconditioning: Ideal for deglazing, honing, and surface finishing of engine cylinder walls during rebuilds and overhauls.
• Surface Preparation: Prepares cylinder bores to achieve the optimal surface texture required for effective piston ring sealing.
• Cross-Hatch Pattern Generation: Essential for establishing the required cross-hatch pattern that promotes proper lubrication and minimizes friction.
• Versatile Material Use: Suitable for application on various cylinder materials, including cast iron and other common engine block alloys.

Benefits

• Improved Engine Performance: Enhances the sealing capabilities of piston rings, contributing to increased compression and overall engine efficiency.
• Optimized Oil Retention: The generated plateau finish effectively retains lubricating oil, leading to better wear protection and extended component life.
• Reduced Oil Consumption: A precisely honed cylinder wall minimizes oil bypass, thereby reducing overall engine oil consumption.
• Extended Engine Longevity: Ensures a proper, long-lasting bore finish that contributes to the durability and reliability of engine components.
• User-Friendly Operation: The self-centering design simplifies the honing process, allowing for consistent and professional results with ease.
