Using Special Service Tool (SST) 09248 - 55040 (09248 - 05410, 09248 - 05420) or equivalent, (A), press down the valve lifter and
place (SST) (B) between the camshaft and valve lifter. Remove (SST) (A).
HINT:
-
Apply (SST) (B) at a slight angle on the side marked with "9" or "7", at the position shown in the illustration.
-
When (SST) (B) is inserted too deeply, it will get pinched by the shim. To prevent it from being stuck, insert it gently from the intake
side, at a slight angle.
-
Using a small screwdriver and magnetic finger, remove the adjusting shim.
b. Determine the replacement adjusting shim size according to this Formula or the Selection Charts:
-
Using a micrometer, measure the thickness of the removed shim.
-
Calculate the thickness of a new shim so the valve clearance comes within the specified value.
T......Thickness of used shim
A......Measured valve clearance
N......Thickness of new shim
Intake: N = T + (A - 0.20 mm (0.008 inch))
Exhaust: N = T + (A - 0.30 mm (0.012 inch))
-
Select a new shim with a thickness as close as possible to the calculated values.
HINT: Shims are available in 17 sizes in increments of 0.050 mm (0.0020 inch), from 2.500 mm (0.0984 inch) to 3.300 mm (0.1299 inch).
