BLOCK CYLINDER HONE 4 5/8" 118MM - Brush Research

Part #: GB45812

Precise Diameter: Specifically engineered for 4 5/8 inch (118 mm) bore sizes, ensuring accurate and consistent material removal.
Engine Block Compatibility: Designed as a block cylinder hone for effective resurfacing and conditioning of internal combustion engine cylinder walls.
Optimal Surface Preparation: Creates the ideal cross-hatch pattern on cylinder surfaces, crucial for proper piston ring seating and lubrication.
Controlled Abrasive Action: Delivers a uniform and controlled finish, preparing cylinders for rebuilds and extending component life.

Engine Rebuilding: Essential for reconditioning cylinder bores during complete engine overhauls.
Cylinder Wall Restoration: Used to remove glaze and minor imperfections from cylinder walls, restoring their integrity.
Piston Ring Seating: Prepares cylinder surfaces to ensure new piston rings achieve optimal sealing and performance.
Automotive and Industrial Maintenance: Applicable for maintenance and repair tasks in various engines matching the specified bore size.

Improved Engine Performance: Facilitates superior piston ring seating, which enhances compression and reduces power loss from blow-by.
Reduced Oil Consumption: A properly honed cylinder surface helps maintain an effective oil film, minimizing oil bypass and consumption.
Extended Engine Life: Contributes to improved longevity of engine components by promoting optimal wear patterns between piston rings and cylinder walls.
Professional Finish: Enables mechanics and engine builders to consistently achieve the precise surface finish required for reliable engine operation.
Accurate Bore Refinement: Delivers consistent results, ensuring cylinder bores are prepared to exact specifications for rebuilds.
