DRIVE BELT INSPECTION [FS]

A3U011015800W01

Inspect the drive belt tension or deflection, as necessary.

Drive Belt Deflection Inspection

Note

Inspect the drive belt deflection when the engine is cold, or at least 30 min after the engine has stopped.

1. Apply moderate pressure 98 N {10 kgf, 22 lbf} 

midway between the specified pulleys.

If the deflection is not within the specification, 
adjust it. (See 01–10B–4 DRIVE BELT 
ADJUSTMENT [FS].)

Drive Belt Tension Inspection

Note

Belt tension can be inspected in place of belt deflection. Inspect the drive belt tension when the engine is 
cold, or at least 30 min after the engine has been stopped.

1. Using the SST, inspect the belt tension between 

any two pulleys.

If the tension is not within the specification, 
adjust it. (See 01–10B–4 DRIVE BELT 
ADJUSTMENT [FS].)

1. Loosen mounting bolt A and B.

2. Adjust the belt deflection or tension by turning the 

adjusting bolt C.

Caution

••••

If the belt is replaced with a new one or 
the belt has been on a running engine for 
less than 5 minutes, adjust deflection or 
tension to “New” specification.

••••

If the belt has been on a running engine 
for more than 5 minutes, adjust 
deflection or tension to “Used” 
specification.

VALVE CLEARANCE INSPECTION [FS]

A3U011012010W01

1. Remove the cylinder head cover. (See 01–10B–10 Cylinder Head Cover Removal Note.)
2. Verify that the engine is in cold condition.
3. Measure the valve clearance.

(1) Turn the crankshaft clockwise so that the 

No.1 piston is at TDC of the compression 
stroke.

(2) Measure the valve clearance at A in the 

figure.

If the valve clearance exceeds the 
standard, replace the adjustment shim. 
(See 01–10B–6 VALVE CLEARANCE 
ADJUSTMENT [FS].)

 clockwise so that 

the No.4 piston is at TDC of the compression 
stroke.

(4) Measure the valve clearance at B in the figure.

If the valve clearance exceeds the standard, replace the adjustment shim. (See 01–10B–6 VALVE 
CLEARANCE ADJUSTMENT [FS].)

VALVE CLEARANCE ADJUSTMENT [FS]

A3U011012010W02

Perform this same procedure for all camshafts requiring valve clearance adjustment.

1. Turn the crankshaft clockwise so that the cams on the camshaft requiring valve clearance adjustment are 

positioned straight up.

2. Remove the camshaft cap bolts as necessary.

Note

Remove only one pair of cap bolts at a time.

Reinstall the cap bolts before removing the 
next pair.
— A: For EX side No.1, 2, 3 cylinder 

adjustment shim removal.

— B: For IN side No.1, 2, 3 cylinder 

adjustment shim removal.

— C: For EX side No.2, 3, 4 cylinder 

adjustment shim removal.

— D: For IN side No.2, 3, 4 cylinder 

adjustment shim removal.

Note

For EX side No.2, 3 cylinder adjustment shim removal, remove bolts either A or C.

For IN side No.2, 3 cylinder adjustment shim removal, remove bolts either B or D.

3. Install the SSTs on the camshaft using the 

camshaft cap bolt holes.

Tightening torque

11.3—14.2 N·m {115—145 kgf·cm, 100—125 

in·lbf}

4. Align the marks on the SSTs (shaft and shaft 

clamp).

5. Tighten bolts A to secure the SST (shaft).
