Inspection
INSPECTION
CAUTION / NOTICE / HINT
NOTICE:
- Make sure the contact surface of the cam timing control motor with EDU
assembly (the surface that contacts the No. 2 timing chain cover
assembly) is free of foreign matter.
- If the cam timing control motor with EDU assembly has been struck or dropped, replace it.
- Do not disassemble the cam timing control motor with EDU assembly. If disassembled, replace it.
PROCEDURE
1. INSPECT CAM TIMING CONTROL MOTOR WITH EDU ASSEMBLY
| (a) Rotate the joint of the cam timing control motor with EDU assembly by hand and check that it rotates smoothly.
Standard Condition: The joint rotates smoothly. HINT:
Due
to the magnetic force of the cam timing control motor with EDU assembly
the joint may feel as if it is sticking when turning it. If the result is not as specified, replace the cam timing control motor with EDU assembly. |
|
2. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY
NOTICE:
- If the camshaft timing gear assembly has been struck or dropped, replace it.
- Do not disassemble the camshaft timing gear assembly. If disassembled, replace it.
| (a) Rotate the camshaft timing gear assembly eccentric shaft by hand.
Standard Condition: The shaft rotates smoothly.
HINT:
- The eccentric shaft may feel difficult to rotate due to the spring inside the camshaft timing gear assembly.
- If the result is not as specified, replace the camshaft timing gear assembly.
| |
| (b) Inspect the joint clearance. (1) Using a vernier caliper, measure the width (A) of the cutout of the camshaft timing gear assembly eccentric shaft.
Standard Width: 5.98 to 6.05 mm (0.235 to 0.238 in.) (2) Using a vernier caliper, measure the width (B) of the joint of the cam timing control motor with EDU assembly.
Standard Width: 5.90 to 5.95 mm (0.232 to 0.234 in.) (3)
Calculate the clearance by subtracting the width (B) of the joint of
the cam timing control motor with EDU assembly from the width (A) of the
cutout of the camshaft timing gear assembly eccentric shaft. Standard Clearance:
0.03 to 0.15 mm (0.00118 to 0.00591 in.) Maximum Clearance:
0.7 mm (0.0276 in.) HINT: If
the clearance is more than the maximum, replace the camshaft timing
gear assembly or cam timing control motor with EDU assembly. | |
Installation
INSTALLATION
CAUTION / NOTICE / HINT
NOTICE:
This
procedure includes the installation of small-head bolts. Refer to
Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.

PROCEDURE
1. INSTALL CAM TIMING CONTROL MOTOR O-RING
| (a)
Install a new cam timing control motor O-ring to the No. 2 timing chain
cover assembly with the protrusion of the cam timing control motor
O-ring oriented as shown in the illustration. | |
2. INSTALL CAM TIMING CONTROL MOTOR WITH EDU ASSEMBLY
HINT:
Perform "Inspection After Repair" after removing and installing, or replacing the cam timing control motor with EDU assembly.
Click here
| (a)
Turn the cutout of the camshaft timing gear assembly eccentric shaft
counterclockwise by hand, and set it to the maximum retard angle
position.
HINT:
- If a camshaft lobe is opening a valve, the eccentric shaft will be difficult to turn.
- When the cutout of the camshaft timing gear assembly eccentric shaft
cannot be turned any farther, it is set to the maximum retard angle.
| |
| (b) Install the cam timing control motor with EDU assembly to the No. 2 timing chain cover assembly.
NOTICE:
- When installing, align the joints of the cam timing control motor with
EDU assembly with the cutouts of the camshaft timing gear assembly
eccentric shaft.
- Align the pin holes of the cam timing control motor with EDU assembly
with the knock pins of the No. 2 timing chain cover assembly when
installing the cam timing control motor with EDU assembly.
- Make sure the contact surface of the cam timing control motor with EDU
assembly (the surface that contacts the No. 2 timing chain cover
assembly) is free of foreign matter.
- When installing the cam timing control motor with EDU assembly, do not use excessive force.
- If the cam timing control motor with EDU assembly has been struck or dropped, replace it.
- Do not disassemble the cam timing control motor with EDU assembly. If disassembled, replace it.
