Valve Spring: Procedures
INSPECTION
Whenever valves have been removed for inspection, reconditioning or replacement, valve springs should be tested. As an example; the compression
length of a spring to be tested is 38.00 mm (1.496 in.). Turn the table of Tool C-647 until surface is in line with the 38.00 mm (1.496 in.) mark on the
threaded stud and the zero mark on 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 two. This will give the spring load at test length. Fractional
measurements are indicated on the table for finer adjustments. Refer to Engine Specifications to obtain specified height and allowable tensions See:
Specifications/Engine Specifications. Replace any springs that do not meet specifications.
