Internal Spring Compressor, short, Size 1 + 2 - Klann Tools

Specifications

The Klann Tools KL-0025-20E Internal Spring Compressor is engineered for demanding automotive suspension work. It weighs 10.32 lbs. With dimensions of approximately 14.57 x 9.09 x 3.54 inches, this compact tool set includes two pairs of spring retainers, sized 1 and 2, to accommodate various coil spring diameters. It features a 19mm hex drive for efficient operation and is built to withstand a maximum load of 30,000 N (approximately 3 tons). The tool offers a clamping width range from 110mm to 287mm, suitable for inner spring diameters down to 75mm and outer spring diameters up to 140mm.

Key Features

• Internal Coil Spring Design: This compressor operates within the coil spring, making it ideal for applications with limited access where external compressors cannot fit.
• Compact "Short" Form Factor: Specifically designed to navigate confined spaces, such as those encountered when working on rear axle springs without requiring the removal of the entire axle beam.
• Interchangeable Pressure Plates: Includes size 1 and size 2 pressure plates (spring retainers) to ensure compatibility with a broad range of spring diameters and configurations.
• Enhanced Safety Mechanisms: Equipped with a 3-point safety interlock system, an automatic free-wheel function, and integrated spindle overload protection for secure and reliable operation.
• Anti-Rotation Profile: Features a corrugated profile that actively prevents distortion of the pressure plates during the compression process, maintaining tool integrity and stability.
• Durable German Engineering: Manufactured in Germany, this tool boasts heavy-duty construction from high-strength steel, ensuring longevity and robust performance.

Applications

This internal spring compressor is an essential tool for automotive technicians and enthusiasts involved in suspension system maintenance and repair. It is particularly effective for:

• Coil Spring Removal and Installation: Facilitates the safe and efficient removal and re-installation of coil springs on various vehicle types.
• Rear Axle Spring Service: Optimally suited for accessing and compressing rear axle springs in tight spaces without the need to lower the entire rear axle assembly.
• Independent Suspension Systems: Ideal for vehicles featuring wishbone and multi-link independent suspension designs where conventional external compressors may not be viable.
• Shock Absorber and Strut Maintenance: Supports the disassembly and assembly of shock absorbers and struts.
• Broad Vehicle Compatibility: Applicable for various models, including specific Mercedes-Benz chassis (e.g., W202, W208, W210, W211, W140, W123, W124, W126, W201), Chrysler vehicles, and certain BMW 1 Series (E87) and 3 Series (E90) models when used with specific pressure plates.

Benefits

• Increased Safety: The internal design, coupled with a 3-point safety lock and spindle overload protection, significantly reduces the risk of slippage and accidents during spring compression, providing peace of mind for the user.
• Enhanced Efficiency: Enables technicians to perform spring service quickly without the time-consuming process of dismantling surrounding axle or suspension components.
• Access in Confined Spaces: Its short, internal configuration allows it to operate effectively in tight areas where larger, external compressors cannot reach, making complex jobs more manageable.
• Precise Control: Applies direct and even compression to the inside of the spring, which helps prevent spring distortion and ensures proper seating during reassembly.
• Versatile Usage: The inclusion of multiple size pressure plates makes this tool adaptable for a wide array of coil spring dimensions, reducing the need for multiple specialized tools.
