Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after this step. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

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-12, "
RECOMMENDED 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
leakage 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.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, 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:
* Transmission/transaxle/CVT fluid. power steering fluid, brake fluid, etc.

CAUTION:
Rotating crankshaft slowly because lifter stopper hits and damages journal portion by rotating
crankshaft quickly.
5. Blow air into the round hole to separate adjusting shim from valve lifter.
CAUTION:
When blowing, use goggles to protect your eye.
6. Remove adjusting shim with magnetic hand.
7. Use the equation below to calculate adjusting shim thickness for replacement.

Using micrometer determine thickness of removed shim with
measured at center.

Calculate thickness of new adjusting shim so valve clearance comes within specified values.
Shims are available in 64 sizes from 2.32 mm (0.0913 in) to 2.95 mm (0.1161 in) in steps of 0.01
mm (0.0004 in). Refer to EM-274, "

How to Select Piston and Bearing ABS00E9Q
DESCRIPTION
*: For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only “0” grade is a vailable.) The
information at the shipment from the plant is described as a reference.

The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.

For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.

For details of the measurement method of each part, the reuse standards, and the selection method of the
selective fitting parts, refer to the text.
HOW TO SELECT PISTON
When New Cylinder Block is Used:
Check the cylinder bore grade (“1”, “2” or “3”) on the rear upper side
between cylinder block banks, and select piston of the same grade.
NOTE:
Piston is available with piston pin as a set for the service part. (Only
“0” grade piston pin is available.)
