(2) Mount the intake camshaft on the air inlet side
a. Place the exhaust camshaft in a position so that dowel pin rotates to a level that is slightly higher than the top surface of
cylinder head (Fig. 134).
b. Smear multi-purpose lubricating grease onto thrust position of intake camshaft.
c. Engage the gears of intake camshaft with the gears of exhaust camshaft following the mounting mark on each gear.
Make sure not to confuse mounting mark with timing mark. (Fig. 135)
