.
CAUTION:
Oil filter must be inserted to the end of O-ring installation
part.
c.
Tighten mounting bolts to the specified torque in the order from
1 to 8 as shown in the figure.
CAUTION:
After tightening mounting bolts, wipe out extra liquid gas-
ket.
NOTE:

by 6.
13. Install crankshaft pulley with the following procedure:
a.
When inserting crankshaft pulley with a plastic hammer, tap on its center portion (not circumference).
CAUTION:

pulley bolt.
d.
Tighten crankshaft pulley bolt.
e.
Put a paint mark
on crankshaft pulley
, matching with any
one of six easy to recognize angle marks
on crankshaft pulley
bolt
flange.
f.
Turn another 60 degrees clockwise (angle tightening).
• Check the tightening angle with movement of one angle mark.
g.
Check that crankshaft rotates clockwise smoothly.

Check for cracks
and any excessive wear
at link plates and
roller links of timing chain. Replace timing chain if necessary.
INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-23, "Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
• Warm up engine thoroughly to check there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*: Power steering fluid, brake fluid, etc.
