Crankshaft belt wheel
, Crankshaft pulley is consisted
of
two
A - type V - belt
to
drive
water
pump
pulley
and
alternator pulley. Dfferent
of
V - belts are used because
of
the different position
of
water
pump
and alternator. V- belt is tensioned by alternator adjustment mecha-
nism.
When
press
the
center
of
V - belt by finger,
10
-15mm
depth should
be
availa-
ble.
Crankshaft timing gear drives idling gear,idling gear drives camshaft timing gear,fuel

7. 1 Air filter
When
the
diesel
engine
is working,clean and fresh air is required
to

cylinder liner,piston t piston rings,
valve and other parts.
For
the
air filter equipped
with
R series diesel engine, besides
one
or
two
types are
equipped by
OEM,
the
common
two
structure styles
are
as

7. 2 Silencer
In order
to
reduce
the
