●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 contacting surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the ▼ marked point.
CAUTION:
When measuring belt tension immediately after belt is installed, first set the tension to the standard.
Then, rotate crankshaft for more than two turns in order to eliminate variance in belt deflection
between the pulleys. Re-measure and adjust the tension to the standard.

CAUTION:
●When belt is replaced with a new one, tighten it a little
stronger than current one to accommodate for insufficient
