• Free Length: 46.5 mm (1.831 in)
• Valve Closed: 38.7 mm at 23.9 kg (1.524 in at 52.7 lb)
• Valve Open: 30.2 mm at 58.5 kg (1.19 in at 129 lb)

1. Measure the free length and the tension of each spring. If the measured value exceeds the specified limit, replace the spring.
2. Check each spring for deformation with a square. Any springs with a deflection of 1.6 mm (0.0630 in) or more must be replaced.
