This valve spring compressor set provides a safe, adaptable solution for mounting and compressing valve springs on most cylinder heads. It includes multiple adapters, a sturdy C clamp jaw, and organized packaging for easy storage and transport. Key benefits - Versatile fit: Includes 5 adapters in different sizes to match a range of spring diameters on most cylinder heads. - Safe and controlled compression: Assists proper spring mounting and uses a reliable compressor for removal and installation. - Durable construction: Built with a strong 1.7 mm thick heat treated steel C clamp jaw with a black oxide finish, designed to resist bending and deformation during use. - Organized storage: 10 pieces are neatly packaged and sorted in a box for safe storage and easy transport. What’s included and compatibility - Adapters: 5 adapters for different spring diameters to ensure proper seating and safe compression. - Packaging: 10 pieces total are well packaged and sorted in a box for storage and transportation. - Compatibility: Suitable for use with most cylinder heads and their valve springs. How to use - Close the coil spring compressor until it touches the center bar, then insert the compressor into the coil spring. - Compress the spring for removal or installation, and release the compression only when the spring is set for installation. - Handle the compressed spring with care, as it stores significant energy that must be decompressed safely. Materials and performance - C Clamp Jaw: Made from 1.7 mm thick heat treated steel with a black oxide treatment, offering strength and resistance to bending or deformation during compression. - Alignment: The two ends of the C clamp are aligned in a straight standard line to minimize slip during use. Use scenarios - Automotive valve service: Replacing or inspecting valve springs during engine maintenance or rebuilds. - Small engines and motorcycles: Servicing valve springs on motorcycles, lawn equipment, or other small engines where compatible adapters are available. - Cylinder head refurbishment: Safe installation and removal of valve springs during cylinder head work or head gasket jobs. Safety and handling - Always be mindful of the stored energy in compressed springs. - Decompress carefully and follow proper procedures during removal and installation. - Use the appropriate adapter to ensure a secure, stable setup before compression.
