Checking Drive BeltsINFOID:0000000009460529
WARNING:
Inspect and check the drive belts with the engine off.
1. Inspect belt for cracks, fraying, wear or o il adhesion. If necessary, replace with a new one.
2. Rotate the crankshaft pulley two times then ensure t he drive belt auto-tensioner is within the possible use
range.
NOTE:
Inspect drive belt tension when engine is cold.
Tension AdjustmentINFOID:0000000009460530
Belt tension is not manually adjustable, it is aut omatically adjusted by the drive belt auto-tensioner.
Removal and InstallationINFOID:0000000009460531
REMOVAL
1. Remove the front RH wheel and tire. Refer to WT-55, "Adjustment".
2. Remove the fender protector side cover RH. Refer to EXT-26, "FENDER PROTECTOR : Removal and
Installation".

3. While securely holding the hexagonal part in pulley center of
drive belt auto-tensioner, move in the direction of arrow (loosen-
ing direction of drive belt auto-tensioner) using suitable tool.
WARNING:
Avoid placing hand in a locat ion where pinching may occur
if the holding tool accidentally comes off.
CAUTION:
Do not loosen the drive belt auto-tensioner pulley bolt. (do
not turn it counterclockwise. ) If turned counterclockwise,
the complete drive belt auto-t ensioner must be replaced as
a unit, including pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter through the rear of drive belt auto-tensioner into retain ing boss to lock drive belt auto-tensioner pulley.
NOTE:
Leave drive belt auto-tensioner pulley arm locked until belt is installed again.
5. Loosen drive belt and then remove it from the other pulleys.
INSTALLATION
1. Install the drive belt onto all of the pulleys.
CAUTION:
Confirm belts are completely set on the pulleys.
2. Release drive belt auto-tensioner, and apply tension to belt. WARNING:
Avoid placing hand in a location wh ere pinching may occur if the holding tool accidentally comes
off.
CAUTION:
Do not loosen the auto-te nsioner pulley bolt. (Don't turn it counterclockwise. If turned counter-
clockwise, the complete auto-tensioner mu st be replaced as a unit, including pulley.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of belt at indicator is within the possible use range. Refer to EM-19, "Checking Drive
Belts".
5. Install the fender protector side cover RH. Refer to EXT-26, "FENDER PROTECTOR : Removal and
Installation".
6. Install the front RH wheel and tire. Refer to WT-55, "Adjustment"
.

CHECKING
• Perform inspection as follows after removal, installation or replace-
ment of camshaft or valve related parts, or if there is unusual
engine conditions regarding valve clearance.
Check valve clearance while engine is cold and not running.
1. Remove the intake manifold collector. Refer to EM-146,
"Removal and Installation".
2. Remove the ignition coils and spark plugs. Refer to EM-132,
"Removal and Installation".
3. Remove the rocker covers. Refer to EM-168, "Removal and
Installation LH" (LH), EM-169, "Removal and Installation RH"
(RH).
4. Set No.1 cylinder at TDC on its compression stroke. • Align pointer with TDC mark on crankshaft pulley.
• Check that the valve lifters on No.1 cylinder are loose and valve lifters on No.4 are tight. If not, turn the crankshaft one full
revolution (360 °) and align as shown.SEM713A

5. Check only the valves as shown.
• Using a feeler gauge, measure the clear ance between the valve lifter and camshaft.
• Record any valve clearance measurements which are out of specification. They will be used later to
determine the required replacement lifter size.
