position beforehand.

6.

Install camshaft.

• Distinction between camshaft (INT and EXH) is performed with

the different shapes of rear end.

• Install camshafts to the cylinder head so that knock pins (A) on

front end are positioned as shown in the figure.

NOTE:
Though camshaft does not stop at the portion as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
