ribs), which drives an alternat or and a water
pump
.
An ignition timing mark (notch) is st amp ed on the
flang
e of the pulley .
The crankshaft pulley is equipped with a to rsio nal
damp
e r to minimize the torsional vibratio n of th e
cranksha
f t as well as sub s t antia lly redu ce no ise and
vib
