Valve Clearance: Adjustments
1. Remove the adjusting shim.
-
Turn the crankshaft to position the cam lobe of the camshaft on the adjusting valve upward.
-
Position the notch of the valve lifter toward the spark plug side.
-
Using Special Service Tool (SST) Valve Clearance Adjust Tool Set # 09248 - 55040 or (A) (Valve Lifter Press # 09248 - 05410), press down
the valve lifter and place SST (B) (Valve Lifter Stopper # 09248 - 05420) or equivalents between the camshaft and valve lifter flange. Remove

2. Determine the replacement adjusting shim size by these.
Formula or Charts:
-
Using a micrometer, measure the thickness of the removed shim.
-
Calculate the thickness of a new shim so that the valve clearance comes within the specified value.
T = Thickness of removed shim.
A = Measured valve clearance.
N = Thickness of new shim.
