Drive Belts
General Information
Belt and pulley replacement guidelines:
• During belt assembly, do NOT force belt into pulley grooves by prying with a
screwdriver, pry bar or similar. This will damage belt side cords, which will cause belt
to turn over in pulley grooves, and result in complete destruction of belt.
• Do NOT use belt dressing.
• Always check condition of remaining belts. Replace belt if worn, cracked,
grease-soaked or oil-soaked.
• When replacing belt and pulley, pulley alignment must be checked under tensioned
condition (brackets securely clamped). A misalignment that can be detected by
visual inspection is detrimental to belt performance.
• Except for belts controlled by an automatic tensioner, if a belt is disturbed for any
reason, it must be tensioned to the correct tension.
• Replace pulleys if worn or clean if still suitable for service.
• On some engines it may be necessary to remove other drive belts to gain access to
a particular belt during replacement. Refer to appropriate sections for information
concerning individual drive belts and proceed accordingly.
