The Caterpillar 316-4262 Garter Spring is a precision-coiled extension spring designed to provide uniform, continuous radial force. It is primarily integrated into internal combustion engine sealing groups and ignition systems to maintain constant lip contact pressure for dynamic seals and to isolate mechanical vibrations.
1. Core Dimensions & Weight
- Free Length: 127.20 mm (5.01 in)
- Wire Diameter: 0.356 mm (0.014 in)
- Overall Spring Inside Diameter: 40.64 mm (1.60 in)
- Net Weight: 0.05 kg (0.10 lbs)
2. Material & Operational Specs
- Material Grade: High-tensile, corrosion-resistant tempered spring steel matrix.
- Functional Design: Interlocking ends forming a continuous circular loop to deliver uniform inward circumferential pressure.
- Environmental Thresholds: Engineered to sustain structural elasticity and resist tension loss under hot oil exposure and tight-clearance ignition compartment dynamics.
3. Equipment & Engine Compatibility
This garter spring serves as a dynamic hardware containment component across wide-bore Caterpillar gas engines and auxiliary modular power networks:
- Gas Engine Configurations: CAT G3408, G3408C, G3412, G3412C, G3508, G3508B, G3508J, G3512, G3512B, G3512J, G3512E, G3516, G3516B, G3516C, G3516E, G3516J, G3520B, G3520C, G3520E, and G3520J platforms.
- Power Generation Modules: Matched with heavy-duty Caterpillar SR4, SR4B, and SR4BHV alternator frameworks.
