RAM 1500 Truck 2WD V8-4.7L (2008)
NOTE: Whenever the valves are removed from the cylinder head it is recommended that the valve springs be inspected and tested for reuse.
Inspect the valve springs for physical signs of wear or damage. Turn table of tool C-647 (1) until surface is in line with the 40.12 mm (1.579 in.) mark on
the threaded stud and the zero mark on the front. Place spring over the stud on the table and lift compressing lever to set tone device. Pull on torque
wrench until a 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 Specifications to obtain specified height and allowable tensions.
Replace any springs that do not meet specifications.
