4 . Belt Cover
The belt cover is made of synthetic resin molding which
is lightweight and heat resistant . It has a totally enclosed
design that utilizes rubber packing at the mating surface
of the cylinder block. This eliminates the chance of dust
and water from entering the interior .
A floating design is utilized by placing rubber mounting
between the cylinder block and belt cover to prevent
the transmission of noise and vibration .
The front belt cover has a graduated line for ignition-
timing confirmation .

5. Camshaft
The DOHC engine uses four camshafts in all ; intake and
exhaust camshafts on the RH bank and intake and
exhaust camshafts on the LH bank.
Each camshaft has a gear which allows the exhaust
camshaft to drive the intake camshaft . The intake cam-
shaft also has a sub gear for eliminating gear backlash,
thereby reducing gear noise.
The cam nose part is finished with "chill" treatment to
increase wear resistance and anti-scuffing properties .
Each camshaft is supported by four journals with three
camshaft caps and a front camshaft cap . Each camshaft
flange is supported by a groove provided in the cylinder
head to receive thrust force.
