Installation

S6JB0A1436051

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.
