The Benefits of Using Automotive Timing Belts

Timing Belt - Advantages

• Precision registration and timing with no loss of high torque carrying capability
• Minimal vibration and chordal effect
• Positive slip proof engagement
• Wide speed range, especially important when the entire speed range is developed from a single source
• Virtually no elongation (stretching) due to wear
• High mechanical efficiency, as much as 98% when properly maintained. By contrast, chain drives are in the 91-98% efficiency range, while V-Belts average in the 93-98% range.
• Power transmission efficiency is not lost with use
• Clean operation, no need for lubrication
• Reduced noise
• Long, dependable trouble-free service
• Excellent abrasion resistance
• Rust resistant
• Resists chemicals and contaminants
• Increased drive design options
• Weight savings
• Safety issues
• Economical operations:
  • No need for expensive drive enclosures
  • No need for lubrication systems
  • No need for tensioning devices
  • No adjustment needed due to stretch or wear
  • No cost for lubricant or disposal fees
  • No worn sprocket replacement
  • No ongoing maintenance costs for roller chain
  • Energy savings
  • Reduced costs associated with "downtime" on top of lost productivity

Timing Belt - Disadvantages

Our own experience has shown that the timing belt is not perfect in every situation when comparing it against a chain drive. Being able to recognize timing belt limitations helps us to educate our customers in making the right decisions on their particular applications needs.

• Availability of numerous chain sizes allows for the use of smaller pitch diameters and/or number of teeth while achieving the desired ratio
• Higher speeds and power capacities
• Detachable chain links make installation easier in some instances
• Need for accurate initial alignment of drive components
• No slippage
• Higher drive ratios at shorter center distances
• Lower bearing loads
• Less affected by temperature or humidity
• Less affected by oil and grease

This topic has been beaten to death, and the consensus is that if there is an advantage, it really isn&#;t worth it.

I think I am the only person to make a case for the advantages of a belt, and even I realize calling these items &#;advantages&#; is a stretch. In the end, the only real advantage is that replacing your water pump at the same time as the timing belt means your water pump will never get a chance to fail, and if you&#;re lucky, your mechanic might find and repair other items that might otherwise fail or cost you more money as a separate job, like a leaky gasket or seal inside the timing belt housing.

BTW, if you can really find someone who will do a full timing belt job for $300 (with the whole kit, not just replacing the belt), take advantage of that opportunity and thank your lucky stars. On many vehicles, timing belt jobs range from $450 (on my Civic) to $900 (on some minivans). You really should get the whole kit, which includes the tensioner pulley and sometimes other important items, depending on the model.
