Engine Drive Belts
Proper operation of engine belt-driven components such as
alternator, fan and water pump depend on proper condition
and tension of the engine drive belt.
NOTE: Belt tension is maintained with an automatic belt
tension device.
The engine drive belt should be inspected visually on a daily
basis. Inspect drive belt should for cracks, frayed areas, and
glazed or shiny surfaces (see Figure 7-3). 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 belt, or by oil, grease, or
hydraulic fluid on the belt.
Refer to engine manufacturer’s manual for special tools or
belt tension specifications.
CAUTION
Do not apply sealant to inside of hydraulic suction hoses.
