1. Check the springs for cracks or other damage.
2. Use a ruler to measure the height of each spring at 4 different locations. A bent spring must be replaced. You can also check the spring for squareness using a steel square and a flat surface. Stand the spring and square on end on a flat surface. Slide the spring up to the square, revolve the spring slowly and observe the space between the top coil of the spring and the square. If the space exceeds 0.10 in. (2.5mm), replace the spring.
3. Measure the free length of the spring using calipers or a suitable service tool. The free length should be approximately 1.61 in. (40.84mm).
4. Check the springs for proper pressure at the specified spring lengths using a valve spring tester. First completely compress the spring 3 times, then measure the tension at 2 different heights. The pressure should be 63 lbs. (280 N) @ 1.34 in. (34mm) and 157 lbs. (700 N) @ 0.984 in. (25mm).
Replace springs with insufficient tension.
