3. In case of not rotating smoothly, remove the fuel high
pressure hose and insert it to the delivery pipe again
after checking damage of the O-ring since there is a
possibility of O-ring engagement.
4. Tighten fuel high pressure hose mounting bolts to the
specified torque.
Tightening Torque: 5.0 ± 1.0 N·m

REMOVAL SERVICE POINTS
A
A" TIMING BELT REMOVAL
1. Rotate the crankshaft clockwise and mate timing marks
with each other to position No.1 cylinder at compression
TDC.
Caution
Ensure that the crankshaft always rotates clockwise.
2. Loosen the mounting bolt of the tensioner pulley and
remove the timing belt.
Caution
When the timing belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.

INSTALLATION SERVICE POINTS
"
AA TIMING BELT B/TIMING BELT B TENSIONER
INSTALLATION
1. Check that timing marks of crankshaft sprocket B and
balancer shaft sprocket are aligned with each other.
2. Install timing belt B to crankshaft sprocket B and balancer
shaft sprocket. Prevent the tension side of the belt from
sagging.
3. Position the center of the timing belt tensioner B at the
center or upper left of the mounting bolt and flange pulley
at the engine front to assemble and fix them temporarily.
4. Adjust the tension of timing belt B.
"
BA TIMING BELT B TENSION ADJUSTMENT
1. Apply force to the timing belt B tensioner in the direction
indicated by the arrow to give tension torque (3.0 ± 0.4
N·m) to the timing belt B so that the tension side of the
timing belt B can become tense. Maintaining the condition,
tighten the mounting bolt to the specified torque for fixing.
Tightening Torque: 19 ± 3 N·m
Caution
Be careful not to let the tensioner rotate together when
tightening the mounting bolt. If the tensioner rotates
together, belt tension becomes too much.
2. Measure the tension of timing belt B by following
procedures.
