Removal and Installation
INFOID:0000000001844926
CAUTION:
The rotating direction indicated in the text indicates all directions seen from the engine front.
REMOVAL
1. Remove front RH wheel. Refer to WT-6, &#34;Rotation&#34;.
2. Remove front fender protector (RH). Refer to EI-23, &#34;
Removal and Installation&#34;.
3. Drain engine oil. Refer to LU-7, &#34;
Changing Engine Oil&#34;.
NOTE:
Perform this step when engine is cold.
4. Remove the following parts.
• Rocker cover: Refer to EM-30, &#34;
Component&#34;.
• Drive belt: Refer to EM-13, &#34;
Removal and Installation&#34;.
• Water pump pulley: Refer to CO-16, &#34;
Component&#34;.
• Ground cable (between engine bracket (RH) and radiator core support)
5. Support the bottom surface of engine using a transmission jack, and then remove the engine bracket and
insulator (RH). Refer to EM-72, &#34;
Component&#34;.
6. Set No. 1 cylinder at TDC on its compression stroke with the following procedure:
a. Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front
cover.
b. At the same time, make sure that the cam noses of the No.1 cyl-
inder are located ( ) as shown.
• If not, rotate crankshaft pulley one revolution (360 degrees)
and align as shown.

7. Hold crankshaft pulley (1) using suitable tool (A) loosen crank-
shaft pulley bolt, and locate bolt seating surface at 10 mm (0.39
in) from its original position.
CAUTION:
Never remove the crankshaft pulley bolt as it will be used as
a supporting point for the pulley puller.
8. Attach a pulley puller (A) in the M6 thread hole on crankshaft
pulley (1), and remove crankshaft pulley.
9. Remove oil pan (lower). Refer to EM-24, &#34;
Component&#34;.
NOTE:
When crankshaft sprocket, oil pump sprocket and other related parts are not removed, this step is unnec-
essary.
10. Remove intake valve timing control solenoid valve.
11. Remove drive belt auto-tensioner.
12. Loosen bolts in reverse order as shown.

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator,
and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-72, &#34;
Component&#34;.
6. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End crank after checking.
• Check engine oil leakage by oil amount adhered to the waste inserted into the oil hole.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
• Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engine oil contamination.
• Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid
valve oil hole of the cylinder head.
• Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-76, &#34;
Component&#34;.
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-5
.
8. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-5
.
9. Installation of the remaining components is in the reverse order of removal
Valve ClearanceINFOID:0000000001702497
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-30
.
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke.
• Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front
cover.
