Engine Drive Belts
The proper operation of engine belt-driven components such
as the alternator, fan clutch, and water pump depend on the
proper condition and tension of the engine drive belts.
NOTE: Belt tension is maintained with an automatic belt
tension device.
The engine drive belt should be inspected visually
(Figure 7-3) on a daily basis. The drive belt should be
inspected for cracks, frayed areas, and glazed or shiny
surfaces. A drive belt that is glazed or shiny indicates belt
slippage.
Engine drive belt damage can be caused by various factors
such as incorrect tension, incorrect belt size, misaligned
engine pulleys, incorrectly installed belts, or by oil, grease, or
hydraulic fluid on the belt.
Refer to the engine manufacturer’s manual for any special
tools or belt tension specifications.
