CAMSHAFT VALVE CLEARANCE
Inspection and AdjustmentINFOID:0000000005930930
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-46, "
Exploded View".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (2) clockwise and align TDC mark(without paint mark) (A) to timing indicator (1) on front cover.
• At the same time, make sure that both intake and exhaust cam noses of No. 1 cylinder face inside as shown.
• If they do not face inside, rotate crankshaft pulley once more (360 degrees) and align as shown.
b. Use a feeler gauge, measure the clearance between valve lifter and camshaft.
• Measure the valve clearances at locations marked “× ” as
shown in the table below [locations indicated with black arrow
( ) as shown] with a feeler gauge.

c. Rotate crankshaft pulley (2) one revolution (360 degrees) and
align TDC mark (without paint mark) (A) to timing indicator (1) on
front cover.
• Measure the valve clearance at locations marked “ ×” as shown
in the table below [locations indicated with black arrow ( ) as
shown] with a feeler gauge.
3. If out of standard, perform adjustment procedure.
ADJUSTMENT
• Perform adjustment depending on selected head thickness of valve lifter.
1. Remove camshaft. Refer to EM-59, "
Exploded View".
2. Remove valve lifters at the locations that are out of the standard.
3. Measure the center thickness of the removed valve lifters with a micrometer (A).
4. Use the equation below to calculate valve lifter thickness for replacement.
