Timing Belt and Belt Tensioner Removal and
Installation
S5JB0B1406051
CAUTION
!
• Never turn injection pump pulley
counterclockwise. It may cause damage of
injection pump.
• After timing belt is removed, never turn
crankshaft and camshafts independently. If
turned, interference may occur between
piston and valves and valves themselves,
and parts related to piston and valves may
be damaged.
• Do not bend or twist timing belt.
• Do not allow timing belt to come into
contact with oil, water, etc. It may be
adversely affect belt life.
• When replacing a timing belt, be sure to
replace timing belt pulley and crankshaft
pulley bolt.
Removal
1) Remove accessory drive belt referring to “Accessory
Drive Belt and Idler Pulley Removal and Installation
in Section 1J”.
2) Remove timing belt cover No.1 (1) and timing belt
cover No.2 (2).
3) Turn crankshaft pulley clockwise, and stop turning
crankshaft pulley immediately before mark (2) of
camshaft pulley (3) matches with mark (1) of belt
inner cover.
4) Remove TDC pin cap, and insert special tool (A) into
TDC pin hole as shown in figure.
