Checking Drive BeltsEBS00LRA
●Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the 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 the 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 value specified 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 cooling water etc.
●Do not twist or bend the belts with strong force.
