DRIVE BELT INSPECTION [ZM]

A3U011015800W03

Drive Belt Deflection Inspection

Note

•

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

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

midway between the specified pulleys.

•

If the deflection exceeds the limit, adjust it.
(See 01–10A–4 DRIVE BELT ADJUSTMENT
[ZM].)

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 exceeds the limit, adjust it. (See
01–10A–4 DRIVE BELT ADJUSTMENT
[ZM].)

DRIVE BELT ADJUSTMENT [ZM]

A3U011015800W04

1. Loosen mounting bolt A, B, and C.

2. Adjust the belt deflection or tension by turning the

adjusting bolt D.

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. Then
warm up the engine, allow it to cool, and
adjust deflection or tension to “Used”
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 [ZM]

A3U011012010W03

1. Remove the cylinder head cover. (See 01–10A–9 TIMING BELT REMOVAL/INSTALLATION [ZM].)
2. Verify that the engine is cold.
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.
