CAUTION:
Do not loosen the hexagonal part in center of drive belt auto-tensioner pulley (Do not turn it counter-
clockwise). If turned counterclockwise, the complete drive belt auto-tensioner must be replaced as a
unit, including the pulley.
INSTALLATION

DRIVE BELTS

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00LRA

Before inspecting engine, make sure engine has cooled down;
wait approximately 30 minutes after engine has been stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB

Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant.

Do not twist or bend the belts with strong force.
