(a) Using SSTs, press down the valve lifter with SST A and hold the valve lifter down with SST B.
SST: 09248-55010
NOTE: Before pressing down the valve lifter, position the notch as shown in the figure.
(b) Remove the adjusting shim with a small screwdriver and magnetic finger.
NOTE: For easy removal of the shim, when setting SST B, set it on the lifter so there is a wide space in the removal direction.
(c) Determine the replacement shim size by using the following Formula or Charts.
^
Using a micrometer, measure the thickness of the shim which was removed.
^
Calculate the thickness of the new shim so the valve clearance comes within specified value.
T = Thickness of shim used
A = Valve clearance measured
N = Thickness of shim new
Intake side: N = T + (A - 0.20 mm (0.008 in.))
Exhaust side: N = T + (A - 0.25 mm (0.010 in.))
^ Select a shim with a thickness as close as possible to the calculated values.
NOTE: Shims are available in 17 sizes, in increments of 0.050 mm (0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299 in.).
(d) Install a new adjusting shim.
^ Place a new adjusting shim on the valve lifter.
^ Using SST A, press down the valve lifter and remove SST B.
