Checking Drive BeltsEBS01EJ4
lBefore inspecting engine, make sure engine has cooled down; wait approximately 30 minutes after engine
has been stopped.
lVisually inspect all belts for wear, damage or cracks on contacting surfaces and edge areas.
lMeasure deflection at the marked point ( ).
CAUTION:
lWhen checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid varia-
tion in deflection between pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.

Deflection AdjustmentEBS01EJ5
lAdjust belts with the parts shown below.
CAUTION:
lWhen a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.
lIf the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
lWhen 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.
lMake sure the belts are fully fitted into the pulley grooves during installation.
lHandle with care to avoid smearing the belts with engine oil or engine coolant.
lDo not twist or bend the belts with strong force.
