Both poly-vee belts have five ribs and a polyester cord as a tension
member. Both belt tensioners are friction-damped. The complete
belt drive is designed for lifetime operation.
Belt drive
For reasons of space, the belt drive for driving the refrigerant com-
pressor, alternator and coolant pump is of two-stage construc-
tion. The torsion vibration damper on the crankshaft drives the
refrigerant compressor via the first pinion gear. The refrigerant
compressor has twin belt pulleys. They transmit drive to the sec-
ond belt drive, which, in turn, drives the alternator with freewheel
and the coolant pump.
