Replace spring if free length or force required to com- press it is not as specified above. Check that free length of spring (28) is 1.47 inches. Use spring gage and check that force required to compress spring to 1.250 inches is 45 to 55 pounds. Check that force required to compress spring to 1.125 inches is 70.2 to 85.8 pounds. Replace spring if free length or force required to compress it is not as specified above. Check that free length of spring (34) is 1.86 inches.
