Description

Universal Clutch Alignment Tool Set – Professional Clutch Installation Solution

Brief Overview

This universal clutch alignment tool set delivers the precision and versatility required for efficient clutch installations across most passenger cars and light commercial vehicles. The kit includes a 147 mm centering shaft with two complete adapter sets—eight conical clutch plate adapters and eight pilot bearing adapters—covering the bore ranges you encounter daily on the shop floor. Whether you're servicing European, Asian, or domestic vehicles, this single kit eliminates the need for multiple specialized tools. Pair this with complementary camshaft alignment equipment to streamline your transmission and driveline service capabilities.

Key Features

  • 147 mm Centering Shaft: Threaded stud design for secure engagement with clutch assembly components; handles for stable control during alignment
  • 8 Conical Clutch Plate Adapters: Range from 12.6 mm to 21.6 mm bore diameters, precisely matching clutch disc hub bores (14–26 mm specification range)
  • 8 Pilot Bearing Adapters: Sizes 10.7 mm to 20.0 mm, ensuring accurate crankshaft pilot bearing alignment
  • Knurled Grip Surfaces: Non-slip edges on larger adapters for safe, controlled hand operation
  • Stamped Size Markings: Clear numerical identification on each adapter for quick selection and inventory management
  • Precision Machining: Smooth bores and internal threads for reliable seating and alignment
  • Blue Molded Carrying Case: Custom-fitted compartments protect each piece and organize the full set for transport and storage

Why This Kit Drives Shop Profitability

Operational Efficiency: Technicians spend less time searching for the right tool size—the complete range is organized and ready. One investment replaces three or four specialty kits, reducing capital tied up in redundant inventory.

Universal Coverage: The 16-adapter design covers the vast majority of clutch jobs your shop encounters, minimizing callbacks for "tool not in stock" scenarios and improving first-visit closure rates.

Professional Presentation: Customers perceive clutch work as more precise and controlled when technicians use dedicated alignment tools. This justifies labor rates and builds confidence in your service quality.

Compact, Portable Design: The molded case fits in service carts and technician toolboxes, enabling shop floor mobility and reducing lost-time searching through fixed tool cabinets.
