paint) (B) to timing indicator (A) on front cover.

• At the same time, make sure that both intake and exhaust cam

noses of No. 1 cylinder face inside (

) as shown in the figure.

• If they do not face inside, rotate crankshaft pulley once more

(360 degrees) and align as shown in the figure.

b.

Use a feeler gauge, measure the clearance between valve lifter
and camshaft.

• By referring to the figure, measure the valve clearances at

locations marked “
