Testing Valve Spring For Compressed Length
Whenever valves have been removed for inspection, reconditioning or replacement, valve springs should be tested. As an example the compression
length of the spring to be tested is 1-5/16 inch. Turn table of Universal Valve Spring Tester Tool until surface is in line with the 1-5/16 inch mark on the
threaded stud. Be sure the zero mark is to the front. Place spring over stud on the table and lift compressing lever to set tone device. Pull on torque
wrench until ping is heard. Take reading on torque wrench at this instant. Multiply this reading by 2. This will give the spring load at test length.
Fractional measurements are indicated on the table for finer adjustments. Refer to specifications to obtain specified height and allowable tensions.
Discard the springs that do not meet specifications.
